Gilsonite is oil well drilling mud additiveFor many years, Gilsonite has been added to drilling fluids to stabilise boreholes through shale stratigraphic intervals, preventing borehole enlargement. It is plugs micro fractures, bedding plane voids, and pore spaces and forms a thin film on the borehole wall. Gilsonite is added at about 1 to 3 kg per barrel of drilling mud. It is also reduces drill string torque and drag, and thus reduces the likelihood of stuck drill [...]

Drilling fluid

The invention relates to a composition comprising an drilling Gilsonite HPHT fluid loss control aid, stable at elevated temperatures and which also acts as an excellent shale stabilizer, bore hold lubricant, sealant for depleted sand, and wall cake conditioner. The HPHT gilsonite fluid loss control aid broadly comprises a Gilsonite (asphaltite, asfaltit,Gilsonita,uintaite, natural asphalt, natural bitumen) which also contains a surfactant such as a nonionic surfactant. The HPHT [...]

FLC 350

The fluid loss control FLC 350 is drilling fluid system is formulated to maintain stability throughout the construction and evaluation of ultra-high temperature wells with bottom hole static temperatures (BHST) of greater than 500 F (260 C). The system will maintain stable rheological profiles with all the characteristics needed to deliver cost-effective drilling rates in thermally hostile down hole environments.Gilsonite natural asphalt acts as a protective colloid in oil-in-water [...]

FLC 550

Fluid loss control additive is desirable to limit the loss of water filtrate from the cement slurry to permeable formation.This is necessary for several reasons:To avoid a modification of the slurry properties (e.g., rheology, density, thickening time)To allow sufficient water to be available for cement hydrationTo minimize hydration of water-sensitive formationsFLC 550 proprietary blended water-soluble additive that stabilizes shale formations, aids in API fluid loss control, [...]
