Water Efficiency & Conservation
Developing energy resources can require large volumes of water. We have extensive procedures and controls in place to ensure that we source, use, recycle and dispose of it responsibly to minimize the impact of our operations.
Onshore, we consumed 86 million barrels of water in 2018 compared to 97 million barrels of water in 2017. This decrease in consumption is due to the divestiture of our Marcellus assets and reduced activity levels in the Eagle Ford Shale. Water withdrawals related to our operations did not have a known significant effect on any water sources.
We recycle and reuse water in our operations whenever practical. In 2018, 4.8 million barrels of flowback and produced water were recycled and reused onshore. This reuse reduces both our freshwater consumption and our produced water disposal volumes.
We have strategically designed our operations infrastructure in the Permian Basin to have options including produced water recycling. This includes a network of water pipelines that enable us to reuse water from one site to another. We increased water recycling in the Permian substantially in 2018.
In the DJ Basin, we continued participation in the South Platte Water Related Activities Program, an organization that allows us to offset water consumption in the DJ Basin to address Endangered Species Act issues related to the South Platte River. The program assists in the recovery of species listed as threatened or endangered under the ESA and works by re-timing water flows to benefit federally listed endangered species.
Onshore Water Disposal
We disposed of 57 million barrels of water in our U.S. onshore operations during 2018. None of this water was discharged to surface water bodies.
Offshore Water Disposal
We have eliminated our freshwater consumption in our offshore operations in 2018. Our operations in Equatorial Guinea utilize a process that circulates seawater through the offshore platforms to produce the freshwater we need. Our offshore Israel operations do not currently use freshwater.
