Diagnosing Excessive Emissions From Faulty Valves at a Permian Central Tank Battery: 63% Emission Reduction

Executive Summary

In a successful collaboration between Qube Technologies and a Permian operator, continuous methane monitoring led to significant emissions reduction at a Central Tank Battery (CTB) in the Southern Midland Basin. The project, initiated in October 2023, utilized four strategically placed monitoring devices to establish baseline emission rates and detect anomalies. When emissions suddenly increased by 2.5 times in February 2024, Qube's alarm system prompted immediate investigation. Through OGI inspection, faulty Enardo valves were identified as the source, complicated by high gas sales line pressure. Following valve replacement, the site achieved a remarkable 63% reduction in emissions, demonstrating the effectiveness of continuous monitoring in identifying and resolving operational issues promptly.
