Oil and Gas (Hydrocarbon) Exploration and Prospecting (oil prospecting) using Remote Sensing Methods - auxiliary solutions for exploration work before conducting 3D seismic surveys and drilling wells.

Thanks to the LANDSAT satellite and SAR (Synthetic Aperture Radar) systems, remote sensing methods for oil and gas exploration have been actively developed since the late 1990s. The application of remote sensing in geological exploration for hydrocarbons has proven to be a mandatory (!) tool for operations related to oil and gas processing and extraction. It aids in infrastructure assessment for well planning and regional reconnaissance during exploration. Hydrocarbon exploration can be broadly divided into two classes: hydrocarbon seepage in water and offshore areas and areas focused on hydrocarbon reservoir content.

The relevance of aerial and space methods for geological tasks is increasing every year. This is due to the progressing development of imaging equipment, the availability of high and very high-resolution Earth images from space, and improved software for processing aerial and satellite images, significantly expanding the possibilities of geological interpretation.

To address hydrocarbon prospecting tasks, a combination of both traditional geophysical and geochemical methods and modern aerial and space methods is necessary. A substantial portion of classical tasks related to substance composition diagnostics, geological boundaries determination, and ore potential assessment can be solved using aerial and satellite imagery.

Implementing these innovative methods in the geological prospecting cycle allows reducing the scope of seismic surveys and drilling, thereby significantly reducing time and financial costs (reducing costs up to 5-15 times compared to traditional methods for unexplored areas and up to 3-5 times for previously well-explored areas) while significantly increasing the reliability of prospecting work.

The identification of prospective geological structures using aerial and satellite images is utilized by project and research organizations, construction companies, and institutions in the oil and gas industry, as well as other interested organizations, to enhance the efficiency of hydrocarbon exploration research.

Purpose of Oil and Gas Exploration (Oil prospecting)

Remote sensing methods help complement traditional geological prospecting work in oil and gas exploration by:

  • identifying zones of anomalous hydrocarbon seepage;
  • detecting increased thermal flow caused by active fluid-thermodynamic processes in reservoirs;
  • assessing the dynamic state of the reservoir and the impact of contemporary tectonic movements on it.

Space imagery and visual observation allow the evaluation of the structural features of shelves, identifying large-scale geological structures that may contain (hydrocarbon) gas and oil deposits.

Studying geological structures in basins, especially lineament anomalies, through remote sensing methods, enables us to find a more precise and reliable approach to discovering hydrocarbon deposits formed under the influence of underground geological pressure and plate tectonics.

The full set of channels provided, for example, by Landsat 8 - 9 (OLI), is the most effective basic data used for studying lineaments, with a focus on visible channels and the panchromatic channel due to their spatial accuracy (when combined, for instance, with high-resolution satellite imagery).

Statistical analysis of lineaments is carried out to understand points of surface pressure and the orientation of geological structures present in the basin.

Lineament maps, lineament density maps, and lineament orientation maps are created to visually comprehend the topography layout. Surface temperature profiles, vegetation trends through NDVI, development of drainage networks, and soil surface profiles serve as indicators for delineating hotspots for oil and gas exploration.

Digital Elevation Model (DEM), thermal range, infrared range, and visible range from Landsat 8 - 9 (OLI) provide essential results for hydrocarbon prospecting.

Objectives and Tasks of Oil and Gas Exploration (Oil prospecting):

Objective of hydrocarbon exploration using remote sensing (RS) methods: Providing reliable evidence and justification for traditional geologists to identify structures of oil and gas deposits (both onshore and offshore) and to pinpoint the locations for drilling exploratory wells.

In both the state and private contexts, the objective is to replenish oil and gas reserves for oil and gas companies.

Tasks of oil and gas exploration:

  • Gathering and preliminary processing of multispectral aerospace information;
  • Synthesis of rational space photoplans;
  • Analysis and investigation of topographic and geological information;
  • Comprehensive analysis of aerospace, geological, and topographic information;
  • Compilation of space-geological maps.

Performing these tasks reveals zones of anomalous hydrocarbon seepage, identifies increased thermal flow caused by active fluid-thermodynamic processes in deposits, and provides an assessment of the dynamic state of the reservoir.

Advantages of using RS data:

Reliability of results obtained in oil and gas exploration:
  • Traditional methods ≈ 25%
  • Systemic aerospace method ≥ 75%

Significant reduction in total costs for oil and gas exploration areas, from 3-5 to 10-15 times, including a reduction in time spent (aerospace methods are the most expedient).
Remote sensing technologies address existing geological issues in oil and gas exploration, including:
  • Studying geomechanical processes using radar interferometry, determining the modern mobility of structures and fault disruptions in sedimentary basins, and their impact on reservoir structure and, consequently, the efficiency of oil and gas field development;
  • Studying and analyzing thermodynamic processes using thermal infrared imaging, influencing the migration of hydrocarbons to the Earth's surface and causing contamination of soil and vegetation cover;
  • Studying biogeochemical factors using infrared imaging, determining changes in spectral characteristics of soil and vegetation cover under the influence of hydrocarbons;
  • In general, low-cost and efficient remote sensing methods provide evidence-based geological information for optimal placement of seismic profiles, exploratory, and production wells.

Thematic analysis of aerospace images for identifying oil and gas prospective areas:

The technology used by "GEO INNOTER" for forecast-prospecting works is based on thematic analysis, expert and automated decoding of aerospace images in all spectral ranges, and comprehensive interpretation of geological-geophysical materials. This technology is primarily aimed at refining the structure of oil and gas accumulation zones and identifying the most promising hydrocarbon traps within them by detecting local structures of various types and fault disruptions through structural analysis of images. Additionally, the technology includes the latest developments in spectral analysis of multispectral aerospace images.

Structural Analysis Method:

The structural analysis method involves visual decoding of aerospace images, as well as automated extraction of lineaments and circular structures capable of visualizing major tectonic disruptions and activations of varying depths. Materials with different levels of detail are subjected to analysis, allowing for information on the characteristics of these structures in different spectral ranges.

Each of these structures undergoes numerous shape recognition procedures, after which it can be determined whether the identified structure is prospective for oil and gas exploration, its depth and thickness of occurrence, as well as its volume and hydrocarbon saturation.

As a result of structural analysis of aerospace images, the following are created:

  • Medium-scale cartographic schemes for forecasting the evaluation of structures with hydrocarbon potential at a scale of 1:100,000;

  • Large-scale plans for forecasting the evaluation of structures with hydrocarbon potential at a scale of 1:10,000.

Spectral Analysis Method:

Multispectral data are essential for solving tasks related to both decoding and determining the real composition of rocks. When processing data, statistical processing methods and spectral analysis of images are employed. The degree of absorption and scattering of sunlight by any object is directly related to its wavelength. The spectral image is a measure of interaction between solar radiation and the Earth's surface, and each geological object has its individual reflective characteristic associated with its chemical composition, degree, and temperature of crystallization, and genesis.

The following spectral analysis methods have been studied and used by "GEO INNOTER":

  • Principal Component Analysis (PCA);
  • Spectral Angle Mapper (SAM);
  • Calculation of mineralogical indices (BR).

The success of remote sensing technology largely depends on the competence of remote sensing specialists and prospecting geologists, their ability to analyze and synthesize, knowledge of physical and chemical processes of hydrocarbon seepage. In general, their ability to select and process remote sensing materials, to compare geological and space information.

Seismic exploration is based on studying the characteristics of elastic wave propagation in the Earth's crust. Elastic vibrations (or seismic waves, as they are also called) are most commonly induced artificially. Seismic waves propagate in rock formations at speeds ranging from 2 to 8 km/s, depending on the density of the rock; the higher the density, the greater the wave propagation speed.

On different stages of the exploration process, a complex of specific activities and research is carried out using modern equipment and tools, including the use of computers and programming, decoding of aerial and satellite images, drilling of wells for various purposes, testing of reservoirs for oil and gas, and other methods.

High efficiency in the search and exploration of oil and gas accumulations is possible only with the conduct of scientifically justified research in specific prospective areas and regions in terms of oil and gas potential, taking into account the general laws of oil and gas formation and distribution in the Earth's crust. When searching for and exploring oil and gas, it is essential to consider economic knowledge, as well as the environment, industrial conditions, and transportation in the areas where exploration activities are planned.

The exploration process for oil and gas includes three consecutive stages: regional, exploration, and development, each of which is subdivided into two phases.

Regional Stage is conducted in unexplored and poorly explored regions or their parts, as well as when searching for hydrocarbon accumulations in deep-seated, poorly studied parts of the section, for example, under rock salt at depths exceeding 4 km, as in the Caspian region.

During the stage of forecasting oil and gas presence, the study of litho-stratigraphic complexes of the deposit section is carried out, structural layers are identified, the main stages of tectonic development of the investigated territory and tectonic zoning are studied. Thus, at this stage, the main features of the geological structure and geological history are established. Then, prospective oil and gas horizons and zones of potential hydrocarbon accumulation are identified. Further, qualitative and quantitative assessments of oil and gas potential are conducted, as well as the selection of main directions and priority objects for further research.

On the next stage of assessing oil and gas accumulation zones, the oil and gas geological zoning is refined, and the largest traps, such as dome structures, with which hydrocarbon accumulation zones may be associated, are identified. Quantitative assessment of hydrocarbon potential is carried out, and areas and priority objects (regional traps) are selected for exploration activities.

Exploration Stage begins when the regional stage is fully completed, and geological justification for exploration activities for oil and gas is done on the identified prospective regional trap. In such traps, a zone of oil and gas accumulation, including a number of oil and gas fields within separate areas - local uplifts or other local traps complicating the regional trap, can be discovered. The exploration stage is divided into two phases, with the first phase further divided into two sub-phases.

The stage of identification and preparation of objects for exploration drilling is divided into sub-phases: 1 - identification of objects, and sub-phase 2 - preparation of objects. During the first sub-phase, conditions and parameters of prospective reservoirs, as well as the most promising local traps (objects, areas), are identified, priority objects are selected, and their preparation for exploration drilling is conducted. For example, if a regional trap is a fold, the largest and well-prepared local structures (anticlines, domes) are selected, among which the order of their preparation for exploration drilling is planned. The most well-prepared structures are those that, according to field geophysical data, are clearly defined in size (length, width, amplitude), configuration, and structural complexities (faults, etc.), if a complex structure is identified.

Large traps cover areas of 50-100 km² and more, medium-sized traps - 10-50 km², small traps - up to 10 km². Priority is given to structures whose resources exceed the average reserves in the region of the deposit. In addition, economic indicators (proximity to deposits, pipelines, distance from deep drilling bases, depth of productive formations, quality of hydrocarbon-bearing rocks, etc.) influence the priority of introducing structures into exploration drilling. During the second sub-phase, detailed studies of identified prospective traps are conducted; objects are selected, and the order of their introduction into exploration drilling is determined; quantitative assessment of hydrocarbon resources on objects prepared for exploration drilling is carried out; and the locations for exploration wells on the prepared objects are selected.

During the exploration stage of the geological exploration process for oil and gas, the main goal is the discovery of hydrocarbon accumulations: either the discovery of a new oil or gas field or the identification of new reservoirs within the explored fields. The tasks to be accomplished at this stage include: identifying productive reservoirs covered by impermeable layers (caprocks), determining reservoir parameters, testing and logging productive horizons and wells, obtaining commercial oil and gas flows, assessing reservoir properties and the physicochemical properties of fluids (oil, gas, condensate, water), estimating the reserves of hydrocarbons in discovered reservoirs, and selecting objects for detailed and evaluative studies.

The development stage is the final stage in the geological exploration process for oil and gas. Exploration is conducted in areas where commercial oil and gas flows have been obtained. The purpose of exploration activities is to assess the discovered oil and gas accumulations and prepare them for development.

The structure of the field is studied, productive reservoirs are identified, and potential oil, gas, condensate, water flow rates, reservoir pressure, and other indicators are determined.

At the first stage of exploration (assessment of fields or reservoirs), the following tasks are carried out: determining the parameters of reservoirs and fields to establish their industrial significance, calculating the reserves of hydrocarbons in reservoirs and fields, selecting objects and stages of exploration, determining the sequence of pilot production and preparing objects for development.

Currently, four main geophysical methods of research are used: seismic, gravimetric, magnetic, and electrical.

The results of our analysis will help in choosing the best ways to lay routes, control spills, and assess damage. GEO INNOTER also performs infrastructure monitoring (including pipelines and oil pipelines), environmental monitoring (oil spill monitoring), construction monitoring, etc.
The purpose of prospecting and exploration processes is to identify, estimate reserves and prepare for development of commercial oil and gas deposits. Geological, geophysical, hydrogeochemical methods, as well as well drilling and exploration are used in the course of prospecting and exploration. Drilling of wells is used to delineate deposits, as well as to determine the depth and thickness of oil and gas bearing strata. While drilling, core-cylindrical samples of rocks occurring at different depths are taken. Analysis of the core allows to determine its oil and gas content. However, core samples are taken along the entire length of the well only in exceptional cases. Therefore, after drilling is completed, it is mandatory to test the well using geophysical methods
Oil prospecting is the process of detecting the presence of oil in the ground or under the seabed. It involves the study of geological structures that may contain oil, and the use of various technologies, such as seismic surveys, well drilling and geochemical analyses, to determine the presence of oil in a particular area. Prospecting activities begin with an assessment of the geological structures on which oil may be located. Then seismic studies are carried out to create a three-dimensional model of underground geological formations. This model can help geologists determine where oil is most likely to be located. After determining the location of the oil, drilling of wells begins to determine the exact quantity and quality of oil. This data is used to determine whether oil production will be economically profitable. Oil prospecting is a complex and expensive process that requires high-tech equipment and specialized knowledge.
Seismic exploration is a method of studying geological formations in the underground layers of the Earth, which is based on the use of seismic waves. This method is used to search for oil, gas, coal and other minerals, as well as to study geological structures associated with earthquakes and other natural disasters. Seismic exploration is carried out by creating artificial seismic waves on the surface of the earth or on the seabed, using explosions, pneumatic or hydraulic shocks, as well as special equipment called seismic sources. These waves propagate through various layers of soil and stone, are reflected from the boundaries of various geological formations and return to the surface, where they are recorded by seismic instruments - geophones. By analyzing the echo signals received from seismic waves, geophysicists can create three-dimensional models of geological formations that can help determine the location of oil and gas, as well as predict the possibility of earthquakes. Seismic prospecting is an important tool for geological research and mining.
Seismic exploration is an important method in the search for oil. To do this, seismic studies are carried out on a large area of the earth's surface, where oil may presumably be located. The research is carried out by creating artificial seismic waves that propagate through various geological layers, and are reflected from the boundaries of various geological formations, and then recorded on the surface using geophones. The results of the seismic survey are analyzed and processed to create a three-dimensional model of geological formations. This model can help geologists determine the location of oil and the extraction of minerals. Seismic exploration makes it possible to determine the size, shape and depth of oil deposits, as well as to assess the quality of oil-bearing rocks. This allows geologists to optimize well drilling and increase the probability of successful oil production.

There are several methods of oil exploration. Some of them include:

  1. Seismic survey: This method has been described above. It is used to create a three-dimensional model of geological formations and determine oil reservoirs.

  2. Gravity and magnetic survey: These methods are based on measuring the gravitational and magnetic fields of the earth in areas where oil is presumed to exist. The presence of oil can lead to changes in the gravitational and magnetic fields, which can help determine the location of the reservoir.

  3. Drilling: This method is used for direct detection of oil. Drilling allows obtaining rock samples and determining the presence of oil in them. However, this method can be costly and requires significant investment in equipment and personnel.

  4. Geochemical methods: This method is based on studying the chemical properties of rocks in areas where oil is presumed to exist. The presence of oil can lead to changes in the composition of rocks, which can be detected and analyzed.

  5. Hydrodynamic methods: This method is based on studying the movement of fluids in geological formations in areas where oil is presumed to exist. This method can help determine the presence of a reservoir and predict oil production volumes.

These methods can be used in various combinations to increase the likelihood of successful oil exploration.


Remote sensing (remote sensing of the Earth) can be used to search for oil in some cases. With the help of remote sensing, it is possible to obtain high-resolution images of the earth's surface, which allows you to detect some signs that may indicate the presence of oil. For example, some types of vegetation can grow in certain conditions that may be associated with the presence of oil underground. These plants can be detected by remote sensing, which can help geologists identify areas where more detailed studies should be carried out. In addition, the presence of certain signs on the surface of the earth, such as pits, cracks or changes in the color of the soil, may also indicate the presence of oil. These signs can be detected in images obtained using remote sensing.

Using Remote Sensing of the Earth (RS) in oil exploration offers several advantages:

  1. Time and cost savings: RS can be used to quickly scan large areas and detect potential oil reservoirs. This can help save time and money that are usually spent on more expensive surveys.

  2. Convenience and accessibility: RS is available in many regions and can be used to scan remote areas where drilling may be impractical or too costly.

  3. Safety and environmental benefits: Using RS for oil exploration can reduce the risks of environmental impact associated with drilling wells and using other oil exploration methods.

  4. Objectivity: RS allows obtaining high-precision and high-resolution surface images, reducing the likelihood of human error in oil exploration.

  5. Integration with other methods: RS can be used in combination with other oil exploration methods such as seismic surveys and gravity surveys to more accurately determine the presence and location of oil.

In summary, using RS in oil exploration provides several advantages that can enhance the efficiency of exploration and reduce research costs.


Distance Sensing of the Earth (RS) is an essential tool in the oil industry and can be used in various aspects of the oil complex, such as:

  1. Search for oil fields: RS can be used to search for oil fields by detecting surface features that may indicate the presence of oil underground. This can help companies identify areas that need further investigation.

  2. Monitoring the condition of oil fields: RS can be used to monitor the condition of oil fields, including changes in land structure, water levels, and vegetation. This can help companies predict potential issues and take precautionary measures.

  3. Evaluation of environmental impact: RS can be used to assess the environmental impact associated with oil extraction. For example, it can be used to detect oil leaks or other environmental pollutants.

  4. Monitoring pipelines and oil pipelines: RS can be used to monitor pipelines and oil pipelines to detect and prevent oil leaks and other hazardous substances.

  5. Determining the location of wells: RS can be used to determine the location of wells and the positioning of oil refineries. This can help companies optimize the placement of their facilities and improve efficiency.

In summary, RS has a wide range of applications in the oil industry and can help companies improve productivity and reduce environmental impact.


Oil is typically found in rock formations that have the capacity to store it within their pores and layers. The main types of rocks where oil is commonly found are sedimentary rocks, such as sandstones, limestones, shales, and clays.

Sandstones are the most common type of rocks where oil deposits form. They consist of quartz grains, clays, and other minerals that create a porous structure capable of holding oil.

Limestones are also frequent rocks where oil can accumulate. They consist of carbonate minerals and usually have cavities and pores where oil can be stored.

Shales and clays can also contain oil, but their porous structure is not as well-developed as in sandstones or limestones. Instead, oil may be present in microscopic voids, pores, or in the form of gas hydrates.

In addition, oil can be found in other types of rocks, such as volcanic rocks, for example, in tuffs and basalts, as well as in carbonate reef systems. However, the most common oil deposits are found in sedimentary rocks.


Oil is one of the most widespread and important natural resources that is used in various spheres of human activity. The main use of oil is fuel production. Gasoline, diesel fuel, aviation kerosene, fuel oil, gas and other fuels are obtained from oil. The fuel obtained from oil is used to drive the engines of cars, airplanes, ships, railway locomotives, etc. In addition to fuel, oil is used for the production of plastics, synthetic fibers, rubber, various chemicals and medicines. It is also a source of raw materials for the production of lubricants, such as motor oils and lubricants. Oil is also used to generate electricity in thermal power plants. In some countries, oil is used to produce coke, which is then used in steel production. In addition, oil is used in the production of bitumen for road surfaces, as well as in the production of paints, varnishes, solvents and other chemical products. Thus, oil has a wide range of applications and is one of the most important resources in the global economy.
The time required to search for oil can vary greatly depending on a number of factors. For example, it may depend on the availability of funds and equipment for exploration, the territory where the search will be conducted, and the geological conditions of this territory. In addition, various equipment and technologies are used in the search for oil, each of which has its own speed of operation. For example, seismic exploration may take from several weeks to several months, depending on the size of the territory and the complexity of geological conditions. Drilling of wells can take from several months to several years, depending on the depth and complexity of the geological structure. It is also necessary to take into account that the search for oil is a time-consuming and expensive process, which can include many stages, starting with exploration and ending with production. Therefore, the time to search for oil may take years or even decades.
Remote sensing data is utilized in oil and gas exploration to identify geological features indicative of hydrocarbon presence. This includes the detection of surface expressions such as seeps, geological structures like faults and folds, and alterations in vegetation that may suggest subsurface hydrocarbon deposits.
Common sensors used in oil prospecting include optical, thermal infrared, and radar sensors. Optical sensors capture visible and near-infrared light for geological mapping, while thermal infrared sensors detect temperature variations. Radar sensors penetrate clouds and vegetation, providing information on surface topography and structural features crucial for oil and gas exploration.
Satellite-based hyperspectral imaging captures a wide range of wavelengths, allowing for detailed analysis of mineral and hydrocarbon signatures. This technology aids in identifying specific minerals associated with hydrocarbon deposits, enhancing the precision of geological mapping during oil and gas exploration.
Remote sensing supports environmental monitoring by assessing changes in land cover, vegetation health, and water quality. It aids in minimizing ecological impacts by providing early detection of potential environmental disturbances, enabling companies to implement mitigation measures and adhere to environmental regulations.
Integrating satellite imagery with GIS technology enhances decision-making in oil prospecting by providing a spatial context for exploration data. This integration enables geospatial analysis, mapping of exploration targets, and planning of infrastructure. It supports a comprehensive understanding of the geological and environmental factors influencing oil and gas exploration, from initial prospecting to production planning.
