Our Leak Detection and Repair (LDAR) program brings strong air regulations and advanced technology together to help protect the environment and ensure the safety of our teams and communities.

Our LDAR program, which we initiated voluntarily to find and fix leaks in 2009, embodies our commitment to respect, protect and work together with our communities within the DJ Basin. We always strive to be better.  Through the combination of today’s advanced infrared technology, innovation and strong regulations, we have progressed our program for reducing leaks and delivering emissions reductions to help improve Colorado’s air quality.

What is LDAR?

In 2013, we worked together with the governor, regulators, the environmental community and peer companies to develop the nation’s most progressive air quality regulations for reducing emissions from oil and natural gas facilities. In 2015, after the Colorado Air Quality Control Commission adopted these rules, which incorporates the use of infrared cameras to aid in leak detection and repair – or LDAR – we advanced our program.

Cutting-edge technology for safety and efficiency

We have a team of trained technicians that monitor and inspect our production facilities and well sites with infrared cameras equipped with advanced thermal imaging technology to detect emissions leaks that cannot be seen with the naked eye. If leaks are detected, our skilled technicians are equipped to repair most of them on the spot.

Our LDAR staff reported more than 13 million components were inspected in 2017 with a leak rate of .04%. Repairs to 80 percent of leaks found were fixed on the spot by LDAR technicians. Leaks requiring equipment change out or major maintenance were completed in an average of 2.5 days.

Why monitor for leaks?

Monitoring for leaks and repairing them is good for the environment and good for business, too. And it is something the state has proactively addressed by adopting strong air regulations. By preventing leaks and improving efficiency, we are reducing emissions and delivering more locally produced, lower-cost energy to customers and communities in Colorado.

Leading the way to reduce emissions

These regulations are part of a much larger, comprehensive regulatory framework in Colorado governing every aspect of the oil and natural gas development process – from the use of completions technology (referred to as hydraulic fracturing or fracking) to rigorous inspection and monitoring requirements for producing wells.

Benefits of the LDAR program

LDAR goes beyond protecting the environment and ensuring the safety of our employees and communities.

By preventing leaks and improving efficiency, we are reducing emissions and delivering more locally produced, lower-cost energy to communities in Colorado.

Reduced leaks and emissions

Leaks from valves, pump seals and other components needing maintenance and repair across our operations have been reduced by more than 70 percent in just three years. And over the last four years in Weld County, VOC emissions decreased 45 percent as Colorado oil production increased 400 percent and natural gas production increased 266 percent (sources: COGCC production data; CDPHE APCD Modeling and Emission Inventory Unit).

Getting it right

For us, the LDAR program is about being a noble neighbor and getting the balance right. With innovation and technology, we can safely produce the energy we need under some of the strongest health, safety and environmental protections in the country.
