BoreVert FLG, is a high-temperature softening-point gilsonite used for high‐temperature, high‐pressure (HTHP) filtration control in all BoreVert oil‐base systems. It is an effective sealant for low‐pressure and depleted formations. It is compatible with all BoreVert systems and can be used in the initial formulation or added later.
- Reduces HTHP fluid loss in High Tempature BoreVert oil‐mud systems
- Enhances emulsion and thermal stability
- Effective at temperatures to 400 degrees F
- Due to the low solubility, it will not increase the viscosity of the oil phase
BoreVert FLG reduces both API and HTHP fluid loss in all oil‐base muds. It helps improve the overall emulsion stability, thermal stability and suspension characteristics.
Typical concentrations range from 2 to 8 lb/bbl, with occasional daily additions in the 0.25 to 0.5 lb/bbl range High‐temperature situations (greater than 400 degrees F) require concentrations, as high as 10 lb/bbl
When used in the initial formulation, it is recommended to add BoreVert FLG last. For existing systems, the product can be added at any time, mixed slowly during at least one complete circulation. Monitor solids control equipment for several circulations to ensure product is not discarded.
