Cement supports and protects well casings and helps achieve zonal isolation. Critical to safer, environmentally sound, and profitable wells, zonal isolation is created and maintained in the wellbore by the cementing process. Whatever your drilling environment or however remote the location, our innovative cementing technologies offer you a range of cementing solutions to achieve zonal isolation for the life of your well.
Understanding deepwater technical challenges is key to designing cementing solutions that meet deepwater specifications and provide required zonal isolation.
Developing high-quality cementing solutions for each type of well environment requires a thorough understanding of the physical properties of both the slurry and the set cement needed.
EverCRETE cementing solution reduces the risk of CO2 degradation and leakage and can be used to cement new CO2 injection wells or plug and abandon existing injection/production wells.
FlexSEAL flexible expanding cement helps ensure well integrity by resisting stresses encountered throughout the well lifecycle. Unlike conventional cement systems, FlexSEAL cement expands after setting, improving cement bonding and blocking hydrocarbon migration. Its low Young’s modulus allows it to absorb cement sheath stresses without cracking.
ThermaSTONE thermally responsive cement expands and contracts with the high pressures and temperatures encountered in heavy oil and geothermal environments.
Effective zonal isolation is critical to ensure efficiency and environmental protection with underground gas storage (UGS) wells. Our technology offers advanced cementing technologies to reduce the risk of unwanted gas migration.
FUTUR self-healing cement ensures long-term zonal isolation and well integrity from production to abandonment—and beyond.
Density control, mud removal, and slurry design are critical to effectively cementing gas-bearing formations and preventing annular gas flow.
Cement additives cure lost circulation and reduce drilling costs.
Effective mud removal is a basic requirement for successful cementing solutions and is the first step in achieving long-term zonal isolation.
Providing the right cementing equipment for every job requires a full line of state-of-the-art technology designed for even the most challenging well environments.
Available software services let you evaluate zonal isolation parameters, calculate pressures, optimize mud removal, evaluate and minimize gas migration risk, and minimize contamination during plug placement.
Noninvasively measure the bond between the casing and the cement and the cement quality with acoustic sonic and ultrasonic tools.
