VISCOUS OLEAGINOUS FLUIDS AND METHODS OF DRILLING AND SERVICING WELLS THEREWITH |
摘要 |
The invention provides (1) a method of increasing the thermal stability of an oleaginous liquid containing a high surface area silica viscosifier therein by adding a water soluble biopolymer thereto; and (2) a drilling, completion, workover, or well servicing fluid comprising an oleaginous liquid, a water soluble biopolymer, and a high surface area silica viscosifier. The method and fluid may optionally contain a low molecular weight polar additive preferably having a molecular weight less than about 400 and containing one or more polar groups per molecule selected from the group consisting of hydroxyl, amino, and mixtures to thereof.
