The HPHT fluid loss control aid broadly comprises Gilsonite, an asphaltic material or solidified hydrocarbon produced by PUB Gilsonite Company in Iran. The Gilsonite employed according to the present invention also contains a surfactant, especially, a nonionic surfactant.
Combination of these compounds as a HPHT fluid loss control aid, reduces HPHT filtrate loss has good stability at elevated temperatures such as at about 300 °F and sometimes as high as 400 °F, stabilizes troublesome shales and decreases bore hole erosion, helps seal depleted sands, reduces torque and drag, causes no adverse effects on the flow properties of the drilling fluid properly conditioned and lowers total well costs.
