Reducing methane emissions: Implementing data science informed operation and maintenance work practices using continuous monitoring technology

Executive Summary

• A privately held Permian Basin operator implemented continuous monitoring (CM) technology using point sensors and data science algorithms to detect, quantify, and localize methane emissions in real-time, replacing traditional semi-annual optical gas imaging (OGI) inspections.

• The new CM system dramatically reduced response time to methane emissions from an estimated 91 days (with semi-annual inspections) to less than 24 hours, representing a 99% improvement in detection and response time.

• Through implementation of improved workflows and operational practices enabled by the CM system, the operator achieved a 79% reduction in monthly methane emissions over one year, demonstrating that continuous monitoring combined with prompt response protocols can significantly improve methane emission management.
