Halliburton 2021 Annual & Sustainability Report Environmental 31 Chemical Stewardship We responsibly manage the environmental risks posed by our chemical products and services over their lifecycle. To improve our chemical stewardship processes and systems, the Global Chemical Stewardship (GCS) team collaborated with internal users to launch a new workflow application, the Chemical Request Management System (ChRMS, pronounced as “charms”). The new system allows users to track the progress of requests for compliance purposes. It also helps us balance the protection of intellectual property with the rights of the chemical manufacturer. Together, in one centralized system and with incorporated global master data, these features deliver a higher level of compliance assurance and facilitate smoother workflows for our personnel. In addition, the integration includes our Safety Data Sheets (SDSs) with information about the safe use of chemicals. Our SDSs are available in 37 languages in more than 70 countries and 20 jurisdictions. We keep all information related to global chemical Sustainable Water Initiative stewardship updated and available to users around The 3R initiative at liquid mud plants the world. The development of ChRMS aligns with our aims to accomplish the following: Halliburton 4.0 approach to digitize the value chain and create internal efficiencies. Reduce Reuse disposal volumes non-aqueous along with dilution fluids in other requirements applications and extend their 3R longevity Repurpose waste fluids in applications in which fluid quality is less critical We work with customers to “3R” all fluids to the fullest extent possible — even proactively cleaning, blending, and reusing most feedstock to help achieve habitual environmental conservation. Not only does this practice save water, but it can prevent some of the emissions associated with the manufacture, transfer, and mixing of new fluids and their components.
