Our Leak Detection and Repair (LDAR) program, which we initiated voluntarily in 2009, brings together our commitments to ensure safe operations, protect the environment, reduce leaks and emissions and improve air quality in Texas and Colorado through the use of advanced technology.

In 2018, the number of components inspected for leak detection and repair decreased as we plugged over 500 facilities, eliminating the emission sources associated with these facilities.  Our LDAR technicians inspected 11,299,225 components across our onshore operations and found leaks in less than 1 percent of the components.  We rapidly began the process of repairing the leaks, with the majority of them repaired in an average of 3 days.

In just four years, the number of leaks we recorded from valves, pump seals and other components needing maintenance and repair have been reduced by more than 70 percent. This reduction is attributable to preventative maintenance, additional leak detection, repair efforts and other factors.

In the Texas Business Unit (Permian Basin and Eagle Ford Shale) we achieved a 25 percent leak reduction in 2018 compared to 2017.
