Understanding and addressing methane emissions is an important step toward net zero, but traditional methodologies of reporting emissions at source level are under increasing scrutiny.
Chevron continues to grow its commitment to reducing emissions and established two equity-based performance measures to reduce greenhouse gas emissions intensity from 2016 to 2023: a 25-30% flaring intensity reduction and a 20-25% methane emissions intensity reduction.
Through its Leak Detection and Repair (LDAR) programme, Chevron uses prior experience to drive a continuous learning process. In some areas, Integrated Operations Centers are used with systems that remotely detect leaks and losses from equipment.
In addition, Chevron has removed or retrofitted all continuous high-bleed pneumatic controllers from its onshore US facilities and now uses low-emitting or non-continuous-bleed technologies to reduce emissions. Where electricity is available, electric and air-driven controllers and pumps are used, which do not emit methane when actuated.
Chevron has piloted several emerging technologies and remains encouraged that more effective and efficient tools will improve LDAR performance in the future. In addition to proprietary testing, Chevron serves on the Industrial Advisory Board of the Methane Emissions Technology Evaluation Center, which tests emerging methane-sensing technologies and evaluates their performance.
Chevron is leveraging its experience in methane emissions reduction to contribute to OGCI’s collective progress in its methane intensity target.
What OGCI member companies are doing to reduce methane emissions
Member companies are expanding leak detection and repair campaigns, removing high-emitting devices, and reducing both flaring and venting.
