Optimize Cement Operation in Any Well

Cementing

Provide the Consistency, Integrity, and Product Quality
for Your Well Conditions
________

Well Integrity is the ultimate goal of the well construction process. Our team has international experience in achieving zonal isolation and cement-sheath integrity in the most technically and economically viable way. As well cementing technology has advanced, special cement systems have been developed to address specific problems.

Engineered solutions for ultralight foamed slurry, efficient mud removal, and lost circulation control aid to optimized operations, enhancing wellbore integrity. With customer needs in mind, we aim to offer a solution to each particular challenge that adds value, whether it is through the technical edge, consistent reliable performance, or simplified operational advantage. Special technologies also exist for problems such as annular fluid migration and cyclic stresses on the sheath.

DOSAS offers high-performance additives for achieving high-quality zonal isolation, allowing for accurate reservoir characterization, maximizing recovery through production optimization operations, and reducing eventual abandonment costs. We actively promote innovative technology and work to solve customers’ formulating and supply challenges through the provision of these customized solutions. Our experts have the highest competency and global experience in environments, including conventional land operations, ultra-Deepwater, HPHT, and tight clearance cementing.

Functions

Latex Gas Migration

Gas migration can occur during cement placement between the end of the cementing operation and setting of the cement and after the cement has set.  Latex additives are used to prevent short-term gas migration.

GASSTOP™ 3000 Latex Gas Migration Control

GASSTOP™ 3000 Latex Gas Migration Control

GasStop™ 3000 is unique as an anti-gas migration agent because it controls fluid loss without adversely affecting the rheology or stability of the slurry....

Cleaning Agent

Nonaqueous drilling fluids leave a thin layer of oil on the casing and formation, preventing a strong cement bond from forming. To help ensure complete zonal isolation and reduce the risk of remedial work, spacer fluids are used to clean residual mud from the wellbore, casing, and formation before cementing operations.

DosSurf™ 10 Surfactant

DosSurf™ 10 Surfactant

DosSurf™ 10 Surfactant is designed to promote phase inversion of an oil external inverted emulsion to be highly effective at degreasing surfaces....

DosSurf™ AG-25 Surfactant

DosSurf™ AG-25 Surfactant

DosSurf ™ AG-25 is based on anionic and non-ionic surfactants. The surfactant package DosSurf™ AG-25 is required for the design of spacer fluids after Non-Aqueous Fluids (NAFs) have been used for drilling. The spacer......
