Liquid Gilsonite “Giltex®”
Liquid Gilsonite Giltex® is liquid additive for drilling fluid is formulated to maintain stability borehole and seal to bridge the pores and micro-fractures and to create an effective barrier that prevents destabilizing pressure transmission into the shale.
Giltex® is compatible with most water-based drilling fluids. Due to the liquid nature of the product, it disperses easily into the mud system, even if added in high concentrations.
Giltex® is thermally stable above 400°F (204°C).
Applications/Functions
- improves shale stability;
- helps to strengthen the borehole walls;
- helps bridge pores, microfractures and permeable zones;
- lowers HTHP fluid loss;
- helps improve filter cake quality and decreaserock sticking tendencies to the bit.
Advantages
- stable at high temperature;
- applicable in most water-based drilling fluids;
- helps improve dynamic and static fluid loss properties.
