Closed-Loop Gas Capture

Minimizing Flaring from Downstream Interruptions Through Innovation and Collaboration

Temporary downstream market interruptions, such as the shutdown of facilities and pipelines for maintenance and repair, can affect the ability to transport gas to processing facilities and result in the need to shut in producing oil wells or flare associated gas. To minimize impacts from downstream market interruptions, EOG has invested in gas gathering and multi-outlet compression stations to allow for multiple takeaway options to provide redundancy in the event of downstream interruptions. We also have control centers in our most active areas designed to manage the flow of our natural gas in real time so that we can avoid flaring.

In 2020, a multi-disciplinary team of EOG employees developed a closed-loop gas capture (CLGC) process to provide an additional alternative to dealing with temporary downstream market interruptions. CLGC is an automated process that re-routes natural gas back into existing wells when a down-stream interruption occurs. After the interruption clears, the well is produced using existing production and measurement equipment.

We conducted a pilot test of CLGC in the Permian Basin in 2020. Results of this pilot test were successful and we are working on expanding our pilot project to additional wells and operating areas. By engaging with regulators and other industry stakeholders, we have also worked to make CLGC a solution that is available for others to use.

By further reducing the dependency on market runtime and using existing infrastructure, we believe CLGC will provide multiple benefits, including:

  • Minimizing Flaring Emissions – by providing a real-time, automated response to reduced market takeaway.
  • Improving Recovery of Resources – by enabling continued production of oil that might have been shut in and the recovery of gas that might otherwise need to be flared.
  • Limiting Surface Disturbance – by using existing compressors, wells and production facilities and requiring minimal additional pipeline infrastructure.

The CLGC Process

  • Producing Wells – oil and associated natural gas is produced.
  • Production Facilities – oil and natural gas is separated.
  • Natural Gas Compression – natural gas is compressed and transported by pipeline to a third-party company for processing and sales.
  • Closed-Loop Gas Capture – natural gas is redirected through an existing well and contained in an oil and natural gas reservoir when a market interruption occurs. When the interruption clears, the natural gas is produced and transported for processing and sale.

Automating LDAR

EOG utilizes proprietary information technology system applications built in-house to capture leak detection and repair (LDAR) data electronically, including a mobile application to capture data directly in the field, real-time. These applications improve the accuracy of our data, identify trends, eliminate paper processes and allow timely repairs throughout our LDAR program.

  • No repair needed – automatic future survey date generated
  • Minor repair made immediately and entered into a proprietary, in-house application for tracking


  • Repairs needed, barcode attached to component, scanned and repair assignment prioritized and automatically sent
  • Photo of component can also be uploaded into a proprietary, in-house application for more detailed repair instructions


  • Repair made, tag is scanned and email alert automatically sent to schedule resurvey


  • Repair surveyed for repair completion
  • Tag scanned and removed and repair recorded in a proprietary, in-house application


  • Repair and survey tickets stored electronically in a proprietary, in-house database for ease of review

Significantly Increasing Reuse in the Powder River Basin

A focus area for the strategic water resources team in 2020 was the continued build out of the water management system and infrastructure for our Powder River Basin operations, which are in early development. Supported by the sourcing, scenario planning and cost analysis tools in TridentSM, the team evaluated how to best apply the practices and technology from our operations in other basins to the unique conditions in the Powder River Basin.

Based on the team’s analysis, EOG implemented water distribution infrastructure utilizing a single reuse collection pond with dual-purpose lines for both sourcing and gathering. This structure allows for produced water to be cycled to and from well pads when needed for drilling or completion operations. In addition, we installed bidirectional pipelines connected to third-party operated commercial evaporation ponds to enhance our reuse capabilities.

Early infrastructure planning and installation of targeted water reuse infrastructure, combined with our Trident technology, has allowed us to source nearly all of our water for our Powder River Basin operations during 2020 from reuse water and minimize truck traffic.

Automating Spill Prevention and Management

To support our efforts to prevent and minimize oil and produced water spills in our operations, EOG has developed a proprietary leak detection software that we call iDetectSM. We began implementing iDetect in our operations in 2019 and continue to roll it out where technically feasible. iDetect uses sensors to detect leaks in real time on flow lines, gathering systems and lay flat lines for temporary water transfers, including reuse water systems.

If a potential leak is detected, iDetect sends a notification through an alarm system linked directly to the mobile devices of our field personnel, which includes a full description and quantification of the potential leak. We have integrated iDetect with our automation systems in our control rooms allowing for remote interventions in our most active areas and shut downs if a leak is detected. Data provided by iDetect also helps with spill prevention by allowing us to evaluate the origins of leaks and better plan our operations, including facility and pipeline designs.

By building iDetect in-house, we are able to regularly deploy new features and data enhancements. We are also able to integrate iDetect with our other applications, including our water management application TridentSM and our automated control systems, providing an efficient and comprehensive system for water and spill management that is adaptable to the unique conditions of our operating areas.

Drones and 3D Elevation Maps

In 2020, we began using drones and fixed wing aircraft to collect aerial imagery and Light Detection and Ranging (LiDar) remote sensing as part of our pre-development planning in the Permian Basin in New Mexico. By combining this high-resolution aerial information with environmental data from national and state government sources, we are able to create three-dimensional elevation maps that enhance our ability to visualize and adjust well pad and infrastructure locations and identify areas for targeted on-site surveys.

Leveraging Our Culture to Help Local Communities

Our community giving and volunteer philosophy reflects our decentralized structure. Our operating area offices and employees are empowered to focus on issues and causes that are relevant to their local communities.

In 2020, the COVID-19 pandemic led to a significant increase in demand for food banks. In response, EOG and its employees donated to more than 40 different food banks across our U.S. operating areas, raising a total of approximately $780,000 in the U.S. In addition, we donated over 2,000 meals to homeless families through the Star of Hope Mission as part of our Houston United Way campaign.

We also donated more than 3,400 masks, other personal protective equipment and meals to health care workers across our operating areas, and contributed financially to a local brewery to make hand sanitizer for first responders in North Dakota.

Our ability to respond to immediate needs across our operating areas at a local level reflects not only the strength of our decentralized culture, but also the collective spirit of giving at EOG.
