Gilsonite asphalt for HTHP filtration control in oil muds
Naturally occurring gilsonite asphalt used for HTHP filtration control in all VERSA oil-base systems. It is used often to seal low-pressure and depleted formations. It is compatible with all VERSA systems and can be used in the initial formulation or added later.
VERSATROL gilsonite reduces both API and HTHP fluid loss in all oil‐base muds. It helps improve the overall emulsion stability, thermal stability and suspension characteristics of most oil‐base formulations. VERSATROL gilsonite also increases viscosity, especially at lower temperatures due to its partial solubility.
