Oil-well cements are used for oil-well grouting, sometimes called oil-well cementing. They consist of either portland or blended cements, plus additives. Oil-well cement must be slow-setting and able to withstand the high temperatures and pressures of these deep wells. The process plays a significant role in well-drilling operations.
Solutions for zonal isolation and integrity. To deliver a successful primary cementing operation, Halliburton optimizes viscosity, thickening time, and strength. Our cementing specialists avert lost circulation through bridging or plugging material, rapid-set or thixotropic cement, or lightweight cement systems. Halliburton ensures the cement sheath can protect the casing, deliver zonal isolation for the life of the well, and withstand cumulative stresses from pressure testing, well
Zonal isolation for each well must be designed and constructed with regard to its unique geological environment. There is no single fit-for-purpose design, well construction, or barrier verification process that is right for all wells . The barrier system that protects usable water includes surface casing and cement.
formed by the rig crew. Today, specialist ser- v.ce companies routinely cement we Is of 20,000 feet 6,098 meters and deeper. Cementing operations are either primary, done in the course of drilling a well, or sec- ondary or remedial, intended to remedy deficiencies in primary cementing or alter the wel completion for production right.
