Cement slurry is a mixture of cement, mix-water, and various additives specifically designed to meet the unique challenges in well construction operations. When pumped into the annular space between the casing and the formation, the cement slurry sets to form a sheath that supports the wellbore, provides zonal isolation and formation integrity, prevents fluid migration, protects the corrosion, controls the well balances and lost circulations, and plugs the abandoned wells in various operational conditions.

FCS ® - Flexible Cement Systems
-
FCS technology is engineeringly approached to improve zonal isolation of the well by controlling and adjusting the mechanical properties of the set cement. With this approach the values of the elastic parameters and amount of expansion are specified to meet the requirement for long term mechanical durability, hence zone isolation.

ELViS ® - Effective Laminar-flow Viscous Spacer
-
ELViS spacer system is engineeringly designed to displace mud effectively prior to cementing using effective laminar-flow technique whenever turbulent flow is not applicable.

LIFT® - Long Interval and Fast-hydration Technology
-
LIFT systems make it easier in cementing long intervals with great temperature variations. LIFT systems control thickening time at high temperature properly while develop compressive strength at low temperature at required operational time frame.

EZCem ® - Mid-to-high Temperature Cementing Technology
-
EZCem is applicable in wide temperature and density range. Its insensitivity to temperature, density, cement brand and mix water minimizes operational risks and improves cementing job quality.

Flow-off ® - Multi-functional Fluid Migration Control Technology
-
Flow-off not only exhibits applicable slurry properties in fluid loss control, rheology, thickening time, compressive strength and free water, but also shows great fluid migration control capacities due to minimal fluid loss.

PETCem ® - Unconventional Density Cementing Technology
-
PETCem technology is normally used when less than 1.5g/cm³ (PETCem LD) or greater than 2.0g/cm³ (PETCem HD) slurry density is required in oilwell cementing design.
