The use of thin priming oils has been proposed where fines and/or sand are present but as the thin priming oil is a very rapid solvent for the powdered asphalt which is added, the mixture thickens almost immediately to a point where it cannot be stored, trans-shipped and laid.
The invention relates to a composition comprising an 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 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.
To achieve these and other advantages, and in accordance with the purpose of the invention, as embodied and broadly described, the invention comprises a composition comprising an HPHT fluid loss control aid stable at elevated temperatures, and which also acts as an excellent shale stabilizer, bore hole lubricant sealant for depleted sands, and wall cake conditioner.
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.
