Repsol
In 2021, Repsol utilized cutting-edge aerial technology to detect and quantify methane emissions in the company’s Marcellus Business Unit. Methane flights and mapping can pinpoint leaking equipment and estimate emissions rates in a cost-effective manner to help improve overall safety. It also allows Repsol and other operators to make changes to reduce leaks, ultimately reducing methane emissions from upstream operations. The process creates a map that images each detected emissions plume.
Following an initial survey that detected emissions from one of Repsol’s well pads, leak detection and repair technicians visited the site and identified malfunctioning liquid level controllers. Operators rebuilt the units to ensure they were functioning properly, and a follow-up survey showed a decrease in emissions, keeping more gas in the pipe
