ExxonMobil has announced an enhanced programme to reduce methane emissions from its facilities across the US.
The programme prioritises actions at sites operated by its subsidiary, XTO Energy, and includes efforts to develop and deploy new, more efficient technologies to detect and reduce facility emissions.
The programme includes a commitment to phase out high-bleed pneumatic devices over three years, extensive personnel training, research, and facility design improvements for new operations.
XTO recently completed a pilot project in the Midland Basin that tested new low-emission designs that use compressed air instead of natural gas to operate pneumatic equipment that helps regulate conditions such as level, flow, pressure and temperature. The results successfully demonstrated the feasibility of using similar designs for new and existing central tank batteries and satellites, to reduce the potential for methane emissions.
XTO’s efforts also include research conducted with ExxonMobil Upstream Research Company and third-party equipment manufacturers to continue development of more efficient, state-of-the-art equipment to detect, quantify and reduce emissions at production sites. These research efforts build on an extensive portfolio of more than 24 existing methane research projects and pilots already under way.
As part of the company’s efforts to better understand the magnitude and characteristics of oil and gas industry-related methane emissions, ExxonMobil participated in studies conducted by the University of Texas and Environmental Defense Fund.
The company remains active in ongoing methane research, including participation in a methane measurement reconciliation study with the Department of Energy’s National Renewable Energy Laboratory, and in supporting research currently underway at Harvard, the University of Texas Energy Initiative, and Stanford University’s Natural Gas Initiative.
