Newfield was an early adopter of methane reduction technology. We voluntarily made the decision to adapt and put into operation green completions technology during each well completion. This has enabled us to capture methane at the wellhead and gather and deliver it to market.
We began to eliminate the use of high-bleed pneumatics in our operations in 2009. Today we have removed all high-bleed controllers from our operations. Further, we minimize the use of low-bleed, intermittent-bleed and no-bleed pneumatic controllers. We may adjust the facility design to operate with fewer controllers or use non-pneumatic devices such as:
- Mechanical valves
- Electronic controllers when electric power is available
- Solar-powered controllers on Utah injection wells
We also use electric or solar powered pumps in place of pneumatic driven pumps at a majority of our well pads.
In accordance with air quality regulations, we design our wells and facilities to avoid intentional venting and minimize venting practices during operations. In North Dakota, we are working closely with midstream partners to improve the capture of produced gas into pipelines. Gas volumes that we are unable to capture are flared as allowed by state regulations. In 2017, we reduced our flared gas volumes by 16 percent from 2015 levels.
We also power our operations with reduced emissions methods wherever feasible.
In the Uinta Basin, we upgraded our workover rigs with cleaner-burning engines that meet or exceed EPA Tier 3 standards. Since 2009, we’ve replaced more than 600 of our older pumpjack engines with more efficient clean-burning units. Additionally, we work to power our well pad operations by electricity when a connection to local utilities is possible.
In our Anadarko Basin operations, a number of rigs are outfitted with bi-fuel engines that run on natural gas.
We recently completed an environmental impact statement for our Uinta Basin operations and have voluntarily committed to implementing a comprehensive suite of emission reduction initiatives. These include plans to minimize flaring, installing low-emission equipment, lending technical support to scientific research and conducting air quality training for our employees.
