The tight gas found in sand is considered one of the important unconventional resources that have been extensively discovered in the Great Sind Basin around the world, characterized by its specific complexities in terms of reservoir properties and the diversity of source materials. This type of sand faces significant challenges in exploration and development due to its unique geological characteristics, such as low permeability and porosity, as well as rapid changes in time and space. In this context, the current study provides a unique insight into the application of advanced methods in integrating well data and seismic data with the aim of creating a relative time framework for analyzing layers in the Penglaizhen formation. This article will discuss the steps of the process that contribute to improving the accuracy of geological information through the use of precise stratigraphic imaging techniques, and how this methodology can support future exploration and development in gas fields.
Introduction to Tight Gas Exploration Techniques in Sedimentary Basins
Tight gas is defined as an unconventional resource widely distributed in many sedimentary basins around the world. The tight gas reserves are characterized by a variety of properties, including low pore space and low permeability. Therefore, its exploration and development pose a significant challenge that requires innovation in exploration methods and techniques. Traditional geophysical methods for searching for these resources exert pressures in meeting exploration needs, necessitating the search for more effective alternatives.
The properties of tight gas require new strategies in seismic imaging that involve a precise understanding of subsurface layer structure. It is essential to utilize well-integrated seismic data to create a reliable relative time framework. This work involves accurately handling seismic data, which helps in predicting the presence of gas within tight sand layers by analyzing seismic characteristics. For example, in the Ludei gas field within the western Jurassic system, these methods were applied through three steps, starting with the creation of a preliminary time framework using defined layers, followed by building a relative time framework until precise time layers are allocated to achieve reliable results in tight gas exploration.
Data Integration Approach of Well and Seismic Data
The essence of advanced geological analysis lies in integrating well data with seismic data to improve the accuracy and reliability of subsurface layer analysis. The integration of well and seismic data is a critical step, as it helps illustrate the relationship between the well environment at depth and seismic data in the time domain. This process leads to a precise understanding of the temporal dimensions of sedimentary components and their interactions.
The approach used involves employing signal layers or geographical markers, relying on seismic data to infer the structure of sandy layers and analyze their properties. This method can enhance the scope of analysis, as precise coherence between seismic data and travel time for each reservoir needs to be achieved. Visual analysis of seismic and well information is an effective way to identify changes in sedimentary properties that influence gas distribution. From this perspective, previous studies have presented successful cases for these techniques, leading to exciting discoveries in the gas field.
Relative Time Framework: Patterns and Standards
The relative time framework serves as the foundation for understanding geological transformations and dealing with the seismic properties of tight gas. This framework integrates geological information from seismic maps and wells, playing a pivotal role in determining the structure and dynamics of deposits. Researchers classify the time layers according to observed features, which enhances the understanding of geological structures and applies predictions during gas exploration.
Using methods such as wedge analysis, specialists can identify precise seismic characteristics that reflect gas levels. The relative time model is also a crucial reference when compensating for seismic patterns and studying the multiple traits of sedimentary networks. This contributes to bridging the gap between outdated understanding and modern trends in the oil industry, enhancing scientists’ ability to make informed decisions during development and exploration operations.
Challenges
Opportunities in Tight Gas Exploration
The process of exploring tight gas involves facing numerous challenges, including rapid changes in geological properties and the difficulty of accurately imaging sand layers.

This represents a technical culture that drives specialists toward new research trends and the application of technological advancements, ultimately enhancing fields’ capacity to extract gas and fossil resources more effectively.
Classifying Indicated Layers and Their Features
Indicated layers are known to represent important elements in geological sciences, serving as benchmarks for dividing parallel geological time layers. These layers are classified based on their characteristics such as rock composition, visual features, and extent. For instance, the Penglaizhen formation in the western Sichuan province during the Jurassic period includes an interleaving of fine brown-grey sands and reddish-brown clay. These layers serve as distinctive temporal benchmarks that can be relied upon for determining geological time periods. These geological features form a foundation for understanding historical changes in the ancient environment, reflecting the diverse sedimentary characteristics and geological processes that occurred over time.
The layers included in the Penglaizhen section are significant due to their deposition periods and the extensive accumulations of non-proliferating sands in the Luodai gas field. This information provides insights into the environmental conditions that prevailed during those periods, including climatic changes and tectonic processes. The technical composition of the rock layers shows diversity attributed to different ecosystems in earth formation, where various time periods reflect the geological record, enhancing our understanding of the dynamics of our illuminated planet.
Seismic Characterization and Data Assessment
Seismic indicators significantly contribute to geological understanding by providing accurate data about the characteristics of different layers. Seismic data are a vital tool in geological interpretation, as they are used to understand the intersections between different rock layers. By using seismic data, scientists can study the transformations that occur in hydrogeological layers, which in turn contributes to assessing mineral and petroleum resources for a clearer view of the composition of the Earth’s crust.
Through the process of layering classification and capturing seismic waves, additional information such as layer thickness and significant changes can be inferred. The classification approach shows how seismic imaging can be utilized to identify geological infrastructure locations and accurately estimate the time periods of their formation, enhancing our capabilities to identify and manage natural hazards and plan infrastructure projects.
Integrated Merging of Rock and Seismic Data
Understanding comprehensive geological insight requires integrating rock data with seismic information to ensure greater accuracy in geological predictions. Scientists use information derived from exploration wells and seismic recordings to create an artificial seismic log based on temporal relationships and geological currency. This process transforms primary data into meaningful information, demonstrating how layer distribution occurs according to time.
Aspects such as reflection properties and wave compliance are employed to comprehensively understand the infrastructure of the layers. For example, if the accuracy of the relationship between seismic data and rock data is verified, locations can be pinpointed with more precision, assisting geologists in planning exploration projects and optimally utilizing geological resources. These technologies offer advanced methods for reaching new conclusions regarding our geological history.
Applications

These applications are vital, as they directly contribute to maintaining the national economy and providing energy.
Moreover, this integration provides new tools for studying environmental changes over time, such as climate change and its impacts on Earth’s environment. Geological studies can be used to predict future changes and plan to address the challenges of the future environment.
Analysis of Sand Gaps Between Wells
Sand gaps are a fundamental part of studying gas and oil fields. In this context, a set of wells like LS55D, LS15, and L84D was analyzed that follow the same sand layer (JP43). This sand belongs to the same river channel believed to have formed during the same time period, adding significant value to the analysis of the geological data extracted from these wells. Such comparisons between wells aid in understanding how materials are deposited and the areas of sand concentration, which helps identify the most promising future exploration areas. Figure 8 shows the comparison chart between wells, particularly between LS55D and LS84D, with important geological lines identified that may clarify the distribution of particles and the internal locations of sandy layers.
Seismic Signals and Geological Data Integration
Seismic data reveals much about the relationship between different layers and their geological history. By studying the seismic data between wells LS25D-3 and LS27, an overlap between the seismic axes of layers JP41-3 and JP42 occurs, assisting in determining the quality and arrangement of the layers. Seismic data facilitates the determination of the time period in which these layers formed, allowing for a better understanding of the environment in which these sandy layers concentrate and the mixing of clay deposits. This overlap is considered important evidence of geological continuity which can be accounted for when making predictions about gas and oil reserves.
Distribution and Mapping of Geological Layers Using Topographic Sections
Topographic sectioning technique is an important factor in analyzing sedimentary layers, especially in narrow sandy systems. This technique allows researchers to break layers into smaller parts, facilitating an understanding of the differences in sediment and sand distribution. Data shows that this technique is effectively used to improve the accuracy of geological structure and contain difficult geological information that is hard to track. Figure 12 displays a profile shape of the topographic section between layers, highlighting the appearance of notable sandy layers that influence the analysis method adopted.
Predictive Analysis of Heterogeneous Deposits
Presenting predictive analysis for heterogeneous deposits represents a significant step in exploring potential resources. It uses seismic attribute analysis, planting seismic data, and studying hydrocarbons to assess the effectiveness of sand gaps. The Lowde gas field is an example of exploring the basic requirements to enhance gas production. By applying attribute characteristics that differentiate between clay and sand, precise locations of rich deposits can be identified, as shown in Figure 14. This type of analysis enables decisions based on reliable data to advance exploration and development processes.
Challenges Facing Tight Reservoirs
The technology for discovering tight reservoirs relies on integrating seismic data with challenges associated with identifying thin layers. These reservoirs often appear with a thickness of less than 10 meters, which leads to difficulties in presenting them independently on seismic images. These challenges necessitate the use of advanced techniques to enhance the possibility of discovering deposits. Additionally, the quality of seismic visibility is closely linked to the accuracy of tangible geological data, where these facts contribute to recognizing the dimensions of gas fields and predicting them with greater accuracy.
ImprovementGeophysical Methods in Analyzing 3D Seismic Data
Seismic data is considered one of the essential tools in exploring and developing oil and gas fields. Many researchers are turning to improve geophysical methods to achieve higher accuracy in analyzing 3D seismic data. This enhancement is primarily achieved by increasing data accuracy and reducing interferences among seismic spectra. This development in technical methods reflects the importance of integrating multi-rapid data, such as drilling data and logging data, to provide a comprehensive picture of the depositional environment and its changes over time. Successful examples of these applications include what Harishidiath did, where he integrated seismic data with drilling data to study the river system during the late Middle Triassic period in the Hammerfest Basin, leading to a significant improvement in seismic interpretation.
Similarly, seismic reflection data were combined with drilling data to study the delta system of lakes in Sag Dong Ying, aiding in the recognition of several fourth-order sequences and the development of a relative temporal seismic model. This underscores the importance of enhanced interpretation techniques, which can help achieve more accurate divisions of research units and ensure consistency in sedimentary time interfaces. Studies show that good analysis and technological innovations play a vital role in improving the accuracy of geological predictions and fundamentally in developing the models used in exploration processes.
Understanding the Temporal Framework in Geological Methods
The high-resolution terminal structure created by integrating seismic and drilling data is an important factor in understanding the time corresponding to sandy formations. The theory relies on dividing time into precise and meticulous periods, reflecting slight changes in the ecosystem that may occur over a short time frame. This method represents a new way to map the interactions of various geological and environmental impacts on rock formations and their surroundings.
This advancement in technologies helps address the phenomenon of narrow sandy layers that are difficult to interpret. By developing an accurate temporal model, researchers can estimate the sub-distribution of sandy layers, opening the doors to improving the accuracy of predictions regarding the locations and sizes of oil reserves. However, it must be remembered that implementing these methods requires a network of high-density wells to adjust the accuracy of extracted seismic signals.
Integrated Data Analysis and Interpretation
The analysis of seismic data and the integration of interpretation techniques highlight the importance of harmonizing various information and variables. By linking well seismic data with other data, such as physical properties and hydrocarbon data, a comprehensive picture of the geological composition can be achieved. This work requires the combination of a diverse mix of geophysical methods for exploring and analyzing data, enhancing the accuracy and significance of the derived results.
One of the prominent studies that embodies this concept is the one carried out by Zing in block Vermilion. There, the research focused on analyzing seismic data horizontally and in a three-dimensional context instead of traditional analytical setups. This enabled a clearer and higher resolution view for analyzing oil and gas reservoirs, contributing to improved prediction accuracy.
Challenges and Future Technologies in Geophysical Fields
While there are many benefits from applying modern technologies, there are also certain limits that must be considered. Achieving a precise temporal framework is a significant challenge due to the need for accurate data collection and the application of complex analytical methods. As technology advances, the integration of geophysical methods with other new technologies should be anticipated to enhance the accuracy of seismic data. This will make the temporal frameworks more compatible with their structural periods.
Many future studies aim to explore new ways to enhance the accuracy of seismic data and ensure its relevance to reality. Building models based on current data and applying modern techniques such as artificial intelligence and machine learning can provide greater accuracy in this field. Thus, continuing research and growth in this area is a key factor in enhancing geological exploration and analysis.
Framework
Ischronous Time and Its Importance in the Geology of Gas Fields
The development of an ischronous time framework, which is considered the foundational layer for understanding the coherence of rock sequences and geological structures, represents a pivotal point in the study of gas fields such as the Luodai Field in the western Sichuan Basin. The main goal of establishing this framework is to improve the accuracy of identifying sedimentary microfacies, which plays a crucial role in enhancing exploration and production methods in resources-rich gas fields. The formation of this framework relies on a precise understanding of sedimentary events and temporal changes in buried layers, which allows for distinguishing the stratigraphic patterns of layers and their movement over time.
There are a number of challenges facing researchers in this field, including the interference of seismic waves that can lead to misinterpretations. Therefore, developing a time framework focused on isochrony could eliminate this problem by accurately linking seismic data with data from wells. The use of wave analysis as a tool for understanding data and its temporal levels has proven effective in achieving this goal. Through this method, researchers can extract temporal and sedimentary characteristics from data taken from wells, allowing for a precise characterization of geological structures and microfacial arrangements.
Moreover, this type of time framework is essential for understanding how sedimentary structures have evolved over time and how they influence the formation of gas resources in fields such as the Luodai Field. The varying opinions among scientists on how to define and utilize isochronous patterns in exploration reflect the scientific depth of this field, where many researchers conduct multiple experiments to test hypotheses regarding the relationship between seismic phases and the chronological sequencing of layers.
Geological Characteristics of the Luodai Field and Exploration Challenges
The Luodai Field is an excellent example of the challenges faced in exploring gas in scientifically complex fields. This field is characterized by fine sandstone deposits buried at great depths. The shallow deposits and clay model are a fundamental part of the field’s structure; however, the diminishing scale of these deposits makes it difficult to accurately discover and estimate the resources within them. What hinders the process the most is that the thickness of these deposits is often less than a quarter of the wavelength of seismic waves, which diminishes the accuracy of seismic analysis in providing correct information about the actual deposits.
Conversely, seismic interpretations based on current data are prone to errors due to the effects resulting from signal interference from different layers. This is attributed to the temporal distance between the resonant waves between upper and lower layers, which may lead to distortions in the translated values in the seismic data. Therefore, constructing an accurate isochronous framework is a vital component in providing significant value in determining the complex geological structure.
Studies have shown that the use of techniques such as spectral analysis and modern technological challenges has given a strong boost to understanding the relationship between environmental and geological changes and the chronological sequence. Understanding these relationships in the Luodai Field enhances geologists’ ability to identify when and how these deposits were formed, providing vital information for drilling strategies and resource exploration.
The Importance of Integrating Data from Wells and Seismology During the Exploration Process
Integrating well and seismic data is a crucial step in achieving a deeper understanding of sedimentary environments. This requires relying on advanced techniques such as wave signal processing and accurate seismic data analysis to execute each component of the isochronous framework. This process contributes to improving the connection between seismic information and well information, allowing researchers to provide accurate descriptions of sedimentary environments.
The techniques used involve merging depth data with time data to strengthen the temporal and geological relationships between these layers. Advanced drilling technology shows that the degree of accuracy of the information significantly increases when seismic data is combined with well data. This enables the development of precise three-dimensional models of gas fields such as the Luodai Field, thereby helping to enhance the efficiency of exploration and production.
In
The conclusion highlights that improving data integration from wells and earthquakes is a key driver in advancing geological research. By using these modern methods, researchers can conduct complex analyses that may contribute to the discovery of new deposits and enhance extraction methods. This research remains a vital part of technological and scientific progress in the field of gas resource geology, reflecting the necessity of continued research and development in this area to ensure the optimal use of these resources.
Introduction
The western Sichuan Valley is one of the important geological regions that hides beneath its surface mineral wealth and hydrocarbon resources, showing a complex composition of various rock layers according to geological studies. Based on the information gathered by researchers in recent years, especially the study by Hu et al. (2018) and Yang et al. (2018), the Penglai Formation has been divided into four main sections arranged from bottom to top: Peng 1, Peng 2, Peng 3, and Peng 4. These sections mainly consist of sands and clay rocks with significant variability in properties and compositions. The data emphasize the importance of these studies for understanding the Earth’s structure and contributing to the exploration of natural resources in the region.
Data and Methods Used
This study used three-dimensional seismic data covering approximately 200 square kilometers, including the total thickness of the Penglai Formation in the study area. The seismic waves have a primary frequency of 40 Hz with recording information from 40 selected wells, providing detailed insights into the stratigraphic distributions in the area. Through comprehensive analysis of the seismic data and its recordings, the position of the marker layers in the three-dimensional seismic data was identified, establishing a temporal framework for the layers. The synthetic records are a vital tool that combines seismic and geophysical information, facilitating the identification of precise geological details.
Marker Layer Division
Marker layers, characterized by stability and clear properties, form the basis for stratigraphic division. The Penglai Formation consists of interbedded layers of clayey sands, along with thicker layers of fine sands and feldspar, posing challenges in identifying the precise properties of these layers. Identifiers from the Shalha and Jinguiyan areas were used to review the marker layers, which undergo significant changes in properties. Experts deal with the division of the hydrological budget in these layers, enabling them to better understand the sedimentological cycle and geometric models in the region.
Determining Layer Boundaries
Technical analysis of the data identified the boundaries of the various layers in the Penglai Formation. For example, the boundaries between layers such as Peng 1 and Peng 2 exhibit specific characteristics identifiable through rock analysis and the use of seismic machinery. The boundary between Peng 1 and the Sweeney Formation is characterized by light sands and deep structures, while the boundary between Peng 2 and Peng 3 reveals detailed insights into ancient activities and sedimentary modeling. The seismic analysis shows stable interfaces, reflecting geological transformations and natural processes over time.
Synthetic Record Logging
Synthetic records are considered modern methods in geological exploration, where records are constructed based on removal and momentum data. These records are created by building resistance curves and reflection layers, representing geological features beneath the surface. In a study relying on the accuracy of the available data, synthetic records are enhanced based on water properties and seismic data, allowing for a deeper understanding of geological processes and environmental characteristics. The markers used in analyzing records assist in extracting important geological interpretations.
Study Results and Practical Applications
The results obtained from these studies demonstrate the importance of accuracy in layer division and the necessity of using sound data in understanding geological processes. By integrating seismic data and recordings, a high level of precision was achieved in identifying stratigraphic structures, which has profound implications for exploring natural resources in the region. The economic significance of these results is substantial, as the developed methods can be used to improve extraction strategies, contributing to the sustainable development of resources.
EstablishmentThe Stratigraphic Framework of Temporal Methodology through the Precise Integration of Well Data and Seismic Data
Establishing a methodical stratigraphic framework characterized by high accuracy is one of the essential elements in exploring subsurface resources. The inability to define the precise relationship between layers in seismic data makes it a sensitive subject. Through the integration of well data and seismic data, the accuracy of information derived from each source is enhanced. In this context, data can be divided into models based on specific time periods, which promotes accurate and reliable interpretation of geological data. A good example of this is seen through the analysis of data from adjacent wells, where sand layers can be accurately defined by matching results between wells considering the temporal differences. Using modern techniques, the distinctive characteristics of sand layers can be identified, progressing towards a better understanding of the geological model with precision.
For instance, when analyzing current well data, it can be concluded that the sand layers in the Louda gas field follow a consistent temporal pattern, indicating that deposition occurred during the same time period. Seismic data provides rich information about layer thickness, aiding in understanding the precise distribution of sands in fluvial deposit settings. The correlation between well data and seismic data facilitates achieving a reliable temporal agreement, representing a qualitative leap in resource exploration processes.
Analysis of Seismic Data and Correlation with Well Data
Every seismic analysis should consider the strengths and weaknesses in both seismic and well data. For example, analyses related to wells such as LS55D-3, LS15, and L84D show that the commonalities in sand layers can be better understood through detailed study of seismic phenomena. Seismic analyses assist in identifying grain size systems, determining the parallelism and pattern of layers, contributing to improvement in understanding how these layers are aggregated.
When considering seismic conditions such as fusion or separation between seismic horizons, such data indicates the importance of accurately tracking layers to avoid errors. For instance, it is known that studying seismic sections shows homogeneity between sand layers in certain areas, which facilitates understanding how sand particles relate to each other in a specific deposition system. Analyzing this data with precision enhances the possibility of accurate predictions regarding the locations of subsurface deposits.
The Series of Stratigraphic Cuts and Their Applications in Identifying Sedimentary Characteristics
The series of stratigraphic cuts gains increasing importance in the context of sedimentary analysis, especially in narrow or thin sand systems. This series allows for a precise analysis of sedimentary joints, contributing to an understanding of the temporal sequence of layers and their differences. By using techniques such as seismic layer cuts, a precise temporal framework based on data can be obtained, demonstrating changes in sedimentary composition and heterogeneity between layers.
When using this technique, examples such as data analysis for the layers between JP31 and JP33−1 serve as strong evidence of its effectiveness in clarifying sedimentation dynamics. With the help of layer cuts, geologists can clearly identify the geological characteristics of the layers and their distribution. This approach analyzes small detail levels, such as thickness, location, and distribution, improving predictions regarding narrow sand locations within the broader sedimentary system.
Analysis of Surface Water Predictions Under the Methodical Temporal Stratigraphic Framework
Accurate predictions for water resources, especially in narrow sand systems, require a meticulous approach based on specific data. This analysis demands a deep understanding of how both seismic and well data are interconnected. The hypothesis is that chronic methodical data enhances the effectiveness of predictions. By utilizing seismic analysis and variance characteristics to allow for accurate extraction of information regarding depth and composition, it becomes clear how to export that data to more accurately define water deposit systems.
This aligns
using methods such as physical capacity analysis and examining the effects of changes in component variability with this effort. These patterns can be used to predict locations of gas emissions and highlight the relationship between sedimentary behavior and accumulation timings. With multiple methods, accuracy and reliability in estimating resources based on geological data can be enhanced.
Characteristics of Seismic Waves and Their Impact on Oil and Gas Storage
Seismic waves play a critical role in understanding the distribution and storage of oil and gas within rock reservoirs. When solid and liquid particles are in a stable state, the attenuation of seismic waves is minimal, leading to an increase in wave intensity. This phenomenon is known as “resonance,” which often occurs at certain low frequencies of seismic waves. As frequency increases, inertial effects amplify, resulting in increased relative velocity between the liquid and solid, reaching a maximum level of attenuation at a specific frequency point. These phenomena are particularly pronounced in oil and gas reservoirs, where seismic records exhibit notable dynamic characteristics of “low-frequency resonance” and “high-frequency attenuation.”
When analyzing seismic data extracted from specific reservoirs, such as lead reservoirs, distinctive acoustic properties emerge that can guide the process of oil and gas exploration. Although the individual thickness of layers may be thin, making it difficult to image them independently, the use of advanced seismic techniques can enhance the accuracy of predicting oil and gas location. For example, seismic measurement data can be used alongside drilling data to create a more precise image of reservoir conditions.
Integration of Seismic Data and Drilling Operations
The integration between drilling data and seismic data is a fundamental aspect in studying clogged sand reservoirs. This process requires the use of a sequential time frame and extensive analyses to ensure data compatibility. In the drilling direction area, results from actual drilling are compared with theoretical models based on seismic data. This facilitated comparison leads to corrections in predictions regarding oil and gas locations, thereby increasing the reliability of the results.
The data extracted from the Luda area indicate that acoustic analyses and inversion results, along with the seismic distribution based on a robust accuracy model, align well with the wells actually drilled, enhancing the credibility of predictions for clogged sand reservoirs. The data also reveal surrounding geological conditions and help pinpoint where oil and gas springs might exist.
Strategies for Developing Hard Rock Reservoirs
During the study of tight sand reservoirs, challenges emerge that affect the rest of the research, such as limited layer thickness and low permeability. Individual layer thicknesses often do not exceed 10 meters, necessitating the use of advanced analytical techniques to improve discovery and development efficiency. Dividing layers into smaller and more precise units can ensure compliance with the sedimentation time interface, contributing to an enhanced overall view of the depositional environment.
With the advancement of technology, enhanced 3D seismic techniques can be used to improve data accuracy and reduce interference between seismic waves. Global studies can also contribute to the development of new methods for understanding and predicting reservoir rocks, such as analyzing different areas and then using the results to improve interpretative accuracy. Processes like system charting describe how sedimentary basins operate, indicating the infrastructure of hydraulic processes and the location of oil and gas reservoirs.
Challenges in Developing Geological Time Frames
One of the significant challenges in developing a time frame is the absence of a fully documented concept of “synchronous time frames.” Despite the difficulty in achieving a true geological timeframe, researchers have come up with various methods to move forward. Improving seismic accuracy should consider geological features and seismic data, which may also ensure the presence of precise sedimentary systems.
Representing
Geological network constraints in the areas under study present an additional challenge. In many cases, adequate facilities are not available to improve the accuracy of the concurrent timescale. In drilling activities, a weak network of wells can lead to significant difficulties in geological interpretation. Therefore, prior success relies on the continuity of increasing data and the improvement of seismic technology to achieve a stronger understanding of geological times.
Fields for “resumption” will therefore be essential to ensure accurate assessment of new fields and to guide upcoming activities toward locations of extractable resources.
Flow System in the Late Triassic of the Eastern Hammerfest Basin
This section addresses the flow system in the Late Triassic of the Eastern Hammerfest Basin in the Barents Sea. This system is considered one of the vital geological systems reflecting the environmental and climatic changes that occurred during that era. The Hammerfest Basin is classified as one of the important basins in the interpretation of oil and gas reservoirs from a sociological perspective. The Triassic era was characterized by many sedimentary systems that contributed to the formation of conditions favorable for hydrocarbon accumulation.
When studying the sedimentary characteristics related to the Hammerfest Basin, it was noted that tectonic influences significantly contributed to the formation of aquatic areas and sedimentary environments. The sedimentary patterns and the shape of the rivers present in the area reveal the extent of the erosion and deposition forces that prevailed at that time. The sedimentary layers also indicate regular changes in the environment, reflecting periods of decrease and increase in marine activity.
The effects of these geological conditions are evident in the Hammerfest Basin’s ability to contain rich hydrocarbon deposits. This makes studying the flow system particularly important for oil researchers in marine areas. Advanced geological analysis methods allow for a better understanding of the relationships between tectonic processes and the sedimentary environment that contributed to the formation of the oil reservoir.
Additional Examples: The presence of pieces of sedimentary rock during drilling can reflect indicators of the quality of the existing deposits and how they are distributed within the geological framework of the basin. Many studies refer to how seismic patterns align with the deposits discovered in the area.
Understanding seismic evidence provides a range of information useful in linking specific settings to geological layer movements and their impacts on natural resource formations.

A group of geology specialists oversees these studies, analyzing the mechanical characteristics of the deposits and identifying the specific environmental patterns that led to the development of these materials. Through these analyses, the factors affecting the hydraulic conductivity of the deposits can be understood, thereby influencing the potential for gas containment.
One of the key criteria studied in this context is the distribution of water gaps and sandy deposits in the observed formation, where studies conducted on this formation confirm that it provides a resource-rich environment. By gathering data from various drilling sites, the depth of the reservoir and the distribution of its contents were accurately determined, facilitating the exploration and production of gas.
A Study Model: Some studies applied advanced techniques to measure the distribution of elements in the sandy rocks of the Pinglaichun Formation, and the results of laboratory tests supported their hypotheses regarding the effectiveness of this formation as a reservoir. This genetic understanding is of great importance in developing more effective strategies for the sustainable exploitation of hydrocarbon resources in the region.
EstablishmentHigh-Precision Strategic Timescale

The strategic timescale is fundamental to understanding different geological periods and their impacts on the formation of hydrocarbon resources.
This research is based on advanced analysis strategies tailored to different depths of rocks and layers. It also includes analysis of membranes and small structures in the rocks to define time periods and understand their effects on geological properties. These studies follow modern techniques such as three-dimensional modeling, allowing for precise identification of temporal and spatial transformations.
Through a proper understanding of this timescale, we can in turn provide accurate assessments of the feasibility of gas and oil exploitation. The conceptual techniques used here may include detailed analysis of seismic waves and monitoring changes in the chemical components of hydrocarbon formations.
Evidence of Effectiveness: There are many practical implications that have shown how these strategic approaches can lead to significant improvements in exploration and development processes.
