Halliburton’s H2 Zero® service is a revolutionary porosity fill sealant that provides unprecedented capabilities for controlling unwanted fluid production. The system is based on an organically crosslinked polymer that forms a permanent seal at the formation matrix . It has a wide temperature range of application (from 60 to 400ºF).
H2 Zero service has been successfully applied to sandstone, carbonate, and shale formations requiring a conformance treatment, solving problems such as water coning/cresting, high-permeability streaks, gravel-pack isolation, fracture shutoff, and/or casing-leak repair. This system has been successfully tested to withstand a differential pressure of at least 2,600 psi and is resistant to acid, CO2, and H2S environments. Because of the capability of the H2 Zero service to withstand pressure, workover operations have been successfully performed in previously treated wells, including acid stimulation, sand control, and frac-pack treatments, among others.
