WPX Energy was recognized this week by the state for its commitment to reducing emissions and helping protect air quality.
One of the rigs WPX uses for drilling in the state’s Piceance Basin in western Colorado runs entirely on natural gas. WPX deployed the new rig last year.
“Using natural gas as a fuel source is better for the environment and helps reduce costs,” said Jeff Cutler, Piceance Basin drilling manager. “Compared to diesel fuel, there’s a 24 percent reduction in overall total emissions and an 80 percent reduction of ozone compounds.”
During initial operations in 2013, the rig saved WPX Energy more than $7,000 in daily fuel costs, and reduced fuel consumption by 85 percent. With less fuel required, truck traffic was also reduced — resulting in less dust, noise and impact to roadways, which benefits neighbors and the local community.
WPX supplies natural gas to the new rig from its existing well pads, where production already occurs. The company has developed more than 4,400 natural gas wells in western Colorado over the years. “Using existing well pads provides a direct fuel source, reduces additional surface disturbance, and takes advantage of the pipelines and infrastructure that are already in place,” said Cutler.
The rig is also capable of moving between multiple wells on a single pad without being disassembled. The rig has four natural gas engines that provide the required horsepower needed to drill both vertical and horizontal well depths between 8,000 to 15,000 feet.
Successfully using the natural gas rig has led WPX to convert six other rigs in Western Colorado to dual-fuel engines that use a combination of both natural gas and diesel.
This is the 16th honor WPX has received from the Colorado Oil and Gas Conservation Commission. The agency also has recognized WPX for water management, water recycling, water quality protection, green completions, use of new technology, reclamation and best practices.
Over the past decade, WPX has invested more than $7.5 billion to develop its holdings in western Colorado’s Piceance Basin. WPX plans to spend $475 million to $495 million in Colorado in 2014.
