Fresh Water Use

Antero’s drilling operations and water withdrawals in West Virginia and Ohio have an overall low to medium water risk, according to the World Resources Institute Aqueduct Water Risk Assessment for Oil and Gas. Antero withdraws 0% of its fresh water from regions with high, or extremely high baseline water stress. Although fresh water is an abundant resource in the Appalachian Basin, Antero is committed to reducing the use of fresh water throughout all of our operations through an active produced water recycling program.

The majority of fresh water is used in the completion of wells. However, a significant amount of fresh water is used in the drilling process to maintain the consistency of the drilling mud and to protect shallow fresh water aquifers. Additionally, we use fresh water during the construction of well pads to meet compaction standards, as well as across Antero’s roads and pads to reduce dust from truck and heavy equipment traffic.

Fresh Water Intensity

Antero’s fresh water intensity is calculated using the amount of fresh water withdrawn from sources listed on the previous page, in cubic meters (m3), divided by the net volume of natural gas Antero produced for the given year. Calculating water intensity is a conventional method for comparing water usage or consumption year over year compared to energy production. Table 7 represents Antero Resources’ fresh water intensity from 2016 through 2019. Antero Resources fresh water intensity decreased by 40% in 2019, primarily due to the increased water recycling and reuse efforts across its operations.
