What Tasks Does Remote Sensing Solve in the Oil and Gas Industry?

Remote sensing and related technologies in the oil and gas industry are not new—they have existed for several decades. For many years, ground-based remote sensing analytics faced several limitations in the oil and gas sector. Twenty years ago, the low spatial and spectral resolution of many data sources made it difficult, for example, to quantify and delineate oil spills or identify hydrothermal minerals beyond a regional scale. These barriers were real, but they no longer exist. Modern remote sensing solutions using spaceborne and airborne sensors have practically eliminated most challenges in the oil and gas industry, not to mention the detailed mapping of infrastructure.

Assets, offices, sites, workers, and operations in the oil and gas industry are geographically dispersed. Thematic maps and models have proven to be the most effective way to visualize and communicate information. There is great potential for using geospatial technologies and developing software in the industry:

• Hydrocarbon Accumulation Potential Map — hydrological modeling; mapping subsurface secondary fluid migration networks; flow direction visualization – accumulation mapping using DEM; possible migration pathways, etc.

  

• Field Analysis — risk segmentation mapping for each oil field element; regional risk mapping; geological maps; ground verification or image verification through field surveys.
• Oil and Gas Area Analysis (incl. 3D UAV and LiDAR models) — rapid assessment and ranking of opportunities using interdisciplinary asset data with weighting and criteria assignment; ranking of sites, oil leases, blocks, and companies; exploration statistics in a visual platform, etc.
• Reserves or Hydrocarbon Volume Estimation — raster analysis based on deterministic prospective reservoir volumes; reserve estimation and spatial analysis of well data for unconventional hydrocarbons such as shale, etc.
• Seismic Planning — terrain analysis; seismic survey maps and data; satellite image processing and spatial analysis; etc.
• Well Planning — planning wells considering multiple drilling constraints; GIS tools used in workflows to optimize well layouts.
• Drilling — spatial analysis to optimize drilling patterns and efficient configurations.
• Production — geospatial technology allows the integration of data and visualization of production volumes, injection rates, and extraction efficiency almost in real time.
• Exploration (Onshore) — a visual framework for asset exploration; 3D modeling of geological, geophysical, and petrophysical hierarchical data.

  

• Bathymetric Mapping — seafloor research; navigation route maps with integrated data; 3D seismic analysis; satellite imagery processing for marine exploration and mapping.
• Field Operations — geospatial technology supports drilling around surface and geological constraints; enhancing extraction efficiency at the reservoir/basin level; integrating and visualizing data in real time for production dashboards; coordinated workflows and field personnel; dynamic hazard modeling for resource distribution; real-time asset tracking; updated DEMs to detect subsidence caused by extraction, and more.
• Facility Management — 3D GIS with UAV-based mapping enables precise tracking of relevant environmental changes almost in real time for health, safety, and environmental monitoring and emergency response (e.g., refineries, gas stations) during oil spills, leaks, explosions, or site fires.
• Transportation System Management — cost-effective route analysis for distribution networks; network analysis for environmentally safe and economical routes; pipeline monitoring for geological hazards and leaks; tracking inspections using remotely obtained data; real-time monitoring and spatial data analysis; seafloor surveying and asset management in offshore operations, etc.

  

  

• Pipeline Routing and Vehicle Tracking — the ecosystem supports tracking valuable assets in this capital-intensive sector. Precise location tracking of vehicles and vessels ensures timely delivery of goods and services as well as effective emergency response.
• Decommissioning — remote sensing data from earlier oil field life cycle stages, centralized in a corporate GIS, helps make optimal decisions regarding infrastructure decommissioning and land reclamation.

Advantages of Using Remote Sensing:

• Facilitates decision-making — determining which area or field to explore, how to optimize the workflow portfolio, how to plan the optimal pipeline route, integrate seismic survey results, plan emergency response, improve asset management, handle pipeline leaks, etc.
• Supports future actions and ongoing exploration — by standardizing processes and reducing technical uncertainty, it enhances exploration efficiency. The GIS platform models coordinated research processes for all company assets. This supports a consistent, verifiable corporate portfolio of potential leads for ongoing portfolio decisions.
• Increases efficiency — integrating interdisciplinary data for risk and uncertainty assessment, improving accessibility to reduce unnecessary downtime, optimizing maintenance schedules.

• Seamless management with real-time map visualization and remote/offshore site, operation, and asset analysis.

  

• Improved communication between spatially distributed locations.
• Data management — massive data sets uploaded into a centralized GIS provide a strong foundation for data governance with full transaction support and reporting tools.

Advantages of Remote Sensing Sensors:

• Synthetic Aperture Radar (InSAR) can be highly useful for assessing terrain stability. It enables enhanced monitoring and control of potential geological hazards in the oil and gas sector. This is an excellent way to improve pipeline safety and performance.

  

• Interferometry allows continuous satellite-based object monitoring. Additionally, ground-based images cannot provide as broad a field of view as satellite images.
• Satellites, global positioning systems, remote sensing devices, and 3D and 4D seismic exploration technologies help detect oil reserves with fewer exploratory wells.
• Environmental monitoring (satellite imagery analysis) — for instance, hydraulic fracturing requires significant water usage and employs potentially hazardous chemicals to release oil from rock formations. In some regions, excessive water use for oil extraction can impact water availability for other needs and potentially affect aquatic habitats. Improper well design or handling can lead to leaks and fluid spills during fracking. Oil contamination is one of the most critical risks to marine environments.
• Satellite SAR — detection of spills, hydrocarbon leak detection, spill assessment, oil and gas seeps.
• Satellites (e.g., MAXAR's WorldView-3) provide high spatial and spectral resolution in strategically located visible and near-infrared (VNIR) bands useful for vegetation analysis, as well as shortwave infrared (SWIR) wavelengths useful for mineral identification. For instance, underground hydrocarbon leaks alter soil chemistry, which manifests as changes in vegetation health.
• A satellite takes multiple images from space and then merges them into one. Exploration costs are reduced fivefold for unexplored areas and sevenfold for well-studied sites compared to traditional methods.

  

• UAVs provide detailed data for 3D seismic planning.

The oil and gas industry was relatively late in adopting remote sensing alongside GIS. However, it is rapidly evolving into the industry with the highest potential for remote sensing-GIS applications throughout the entire life cycle. Moreover, it enables seamless integration of geospatial technologies, such as UAVs, sensors, and existing computer systems, within the remote sensing-GIS framework. This helps companies compete in the global race for new energy sources and maximize the value of their assets.

Application Examples

Accurate and Intuitive Database Design – Fully Customizable Classification of Oil and Gas Infrastructure Maps Using Remote Sensing Data

Planimetric maps are essential for supporting planning and decision-making throughout the entire lifecycle of oil and gas operations, including exploration, infrastructure management, environmental planning, and spatial analysis. Advanced methodologies for extracting oil and gas-related objects ensure fully customizable maps with layers that can be grouped and classified for optimal data visualization and analysis. Extracted objects are also used to populate geographically coded databases that can be easily referenced in tabular formats.

Monitoring Oil Pollution in Vegetated Areas Using Optical Remote Sensing

Monitoring soil pollution caused by oil and gas industry activities remains challenging in vegetated regions. Over the past decade, optical remote sensing has proven useful for this purpose. By tracking biochemical changes in vegetation through its optical properties, multi- and hyperspectral remote sensing allows the detection and quantification of crude oil and petroleum products that have seeped into the environment due to accidental spills or improper site closure practices. Recent advancements in this field have led to the development of various methods that can be applied in the field using portable spectroradiometers or on a larger scale using aerial and satellite imagery. Experiments conducted in controlled environments have significantly contributed to understanding the key factors affecting oil detection (e.g., plant species, mixture composition, etc.). From an operational perspective, significant efforts are still required to make optical remote sensing a reliable tool for oil and gas companies. Current image-based methods need to expand their applicability to a broader range of contexts, and their integration with upcoming hyperspectral satellite sensors should be explored in future research.

Major sources of environmental pollution resulting from oil activities include: (a) oil sludge pits, (b-c) vegetation and soil contaminated by crude oil spills near refineries, (d) pipeline leaks, (e) crop contamination due to well blowouts, (f) oil leaks from damaged storage tanks after hurricanes, and (g) wastewater pollution near production sites.

Using Radar Remote Sensing for Offshore Oil and Gas Exploration and Environmental Protection: Detection and Interpretation of Oil Spills (Seeps and Spills)

Airborne and satellite-based radar remote sensing technologies are used for detecting oil spills in operational contexts. An oil layer on the sea surface dampens so-called "capillary waves," which are responsible for ocean surface roughness. Research results are presented as "field examples" along with R&D developments related to emerging detection methods. An evaluation of the most important polarimetric parameters for detecting and characterizing oil slicks is provided. Various radar frequencies (X, L bands, etc.) are utilized for detection, characterization, and relative thickness assessment. Finally, in the event of a significant spill, the "Spill Watch" procedure is activated to monitor and predict the oil slick's drift, helping response teams determine where anti-pollution efforts should be concentrated.

Oil Well Data Acquired Using Satellite Remote Sensing

Assessing the number and geographic locations of oil wells is crucial for policymakers due to their impact on energy resource planning. Thanks to recent advancements in optical remote sensing, it has become possible to identify oil wells using satellite imagery. Moreover, the latest developments in deep learning for object detection in remote sensing images make it possible to automatically detect oil wells from satellite data. In this study, a dataset named Northeast Petroleum University-Oil Well Object Detection Version 1.0 (NEPU-OWOD V1.0) was created based on high-resolution remote sensing images. It includes 1,192 oil wells across 432 images from Daqing, the largest oil field in China. This study compared nine different state-of-the-art deep learning models for object detection in optical remote sensing images. Experimental results show that modern deep learning models achieve high accuracy on this dataset, demonstrating significant potential for oil well detection using remote sensing.
