BT-SP Cement Spacer
Overviews
BT-SP(the equivalent of SA-541TM Control Agent) cement spacer relies on rheology to efficiently displace drilling fluid. Because its rheology remains relatively flat across a broad range of shear rates, BT-SP cement spacer promotes a more uniform flow velocity. These superior fluid mechanics help ensure better cleaning of the wellbore and enable recovery and reuse of expensive synthetic-based drilling mud.
BT-SP cement spacer can be customized to satisfy the requirements of any wellbore geometry, and operators can adjust the concentration of the base mix to fine-tune the spacer viscosity to meet specific demands of the drilling mud.
The consistent rheology of BT-SP cement spacer can provide operators with complete control over mixing, pumping, and equivalent circulating densities (ECDs).BT-SP cement spacer is not classified as hazardous waste by the Environmental Protection Agency.
