Stay informed about the latest DOSAS products (if desired)
DOSAS offers high performance cementing additives which make it possible to accommodate a wide range of conditions. Systems for well cementing are routinely designed to perform at temperatures ranging from permafrost zones to thermal-recovery wells and pressures from ambient to high pressured deep wells. In addition to severe temperatures and pressures, well cement must often be designed for weak or porous formations, corrosive fluids, and overpressured formation fluids.
Our additives modify the behavior of the cement system, ensuring successful slurry placement between the casing and the formation, rapid compressive strength development, and adequate zonal isolation during the lifetime of the well. We actively promote innovative technology and work to solve customers’ formulating and supply challenges through the provision of customized solutions.
Our cementing experts have the highest competency and global experience in environments, including conventional land operations, ultra-deepwater, HPHT and gas-tight cementing.
Synthetic cementing retarder recommended in controlling the setting of the cement slurry in applications with medium to high bottom hole circulating temperatures.
