Thixotropic / Expanding Cement Additives

GT XLLiquid thixotropic cement additive; non-expanding; used in all Portland cements, normal concentration is 0.6 to 1.0 gal/sk.
GT XPThixotropic/expanding cement additive; used in Portland cement having a C3A level of 5% minimum; optimum concentration is 10-12% BWOC.

Foam Cement Additive

GFC ILLiquid foaming agent; is very effective to 95°C; creates stable cement slurry densities to as low as 6.0 lb./gal.

Gas Control Additive

GCA 1LLatex gas control additive; prevents gas cutting of cement column or creation of micro-annulus after cement placement across high-pressure gas zones effective at temperatures up to 135°C (BHST); optimum concentration is 1.5 to 3.0 gal/sk of cement.

Salt Cement Slurries

GSS 1Tech grade sodium chloride (NaC1) for cementing across salt sections; used at concentrations from 18% to 37.2% BWOW.

Formation Control / Sealer System

FORMA LOK 1In-situ blend of divalent salt brine and silicate gallant to plug off underground thief zones and seal off underground aquifers; rapid gel strength development.
FORMA LOK 2In-situ blend of divalent salt brine, silicate gallant and Portland cement to plug off underground thief zones and seal off underground aquifers; permanent seal, rapid gel strength development and rapid set.
