Halliburton 2021 Annual & Sustainability Report Environmental 39 Cementing Products The Cementing PSL has two main focus areas: to reduce the carbon footprint of the solutions that we provide to our customers and to stop fugitive gas emissions for the life of a well. NeoCem™ IsoBond™ Obex™ The NeoCem™ cement system The IsoBond™ cement system Our Obex™ family of compression- reduces the amount of Portland prevents sustained casing pressure set, mechanical packers (Obex cement in the wellbore isolation over the life of a well, which helps GasLock™ packer, V0 rated; Obex barrier by an average of 40% by mass improve well integrity and stop IsoLock™, V3 rated; and Obex Portland. (Portland cement accounts fugitive gas emissions from releasing EcoLock™, V6 rated) enhance well for the majority of the carbon into the environment. The system integrity and therefore prevent footprint in a cementing job, as its accomplishes this through: fugitive gas emissions. By offering a manufacture and transport releases • Low fluid loss and fast transition powerful mechanical barrier, Obex™ air pollutants.) times to prevent the flow of gas packers improve zonal isolation and through cement as it sets. mitigate sustained casing pressure to avoid failures leading to annular • Enhanced shear bond, in which gas migration. the ability of the cement to adhere to steel casing improves by as much as 40% compared to other cementing systems. • Reduced cement permeability by more than 70% compared to other cementing systems, which prevents gas and other wellbore fluids from migrating through the cement after it sets.
