Halliburton 2021 Annual & Sustainability Report Environmental 32 Water and Effluents We work with our customers to reduce their water usage. Although customers purchase and control the water they use at hydraulic fracturing sites and at wellsites, we provide solutions to assist customers with water usage. Our reported water-usage data includes water used at Company-owned or Company-leased locations, except those locations that include water usage in the lease, and covers our facilities in the U.S. and Canada and most global facilities. Many of our locations have implemented water-reduction and water-recycling projects, particularly those in water- stressed areas.

This eliminates the requirement to use fresh water for every test. Thailand Our water treatment system cleans and separates oil discharge from water. The Thai government allows Halliburton to sell the water to a recycling company. Argentina At the Añelo Field Camp, we built a water-treatment plant that we completed in January 2022. The plant enables us to reuse 88% of the wastewater generated in our washbays.
