Dissipative Surfactant Aqueous-Based Drilling System for Use in Hydrocarbon Recovery Operations from Heavy Oil and Tar Sands |
| abstract |
A water-based drilling fluid which includes an aqueous fluid and a water-soluble dissipative surfactant composition is described, wherein the dissipative surfactant composition includes at least one fatty acid or ester derivative of a plant or vegetable oil. Also described are methods of using such aqueous-based drilling fluids including the dissipative surfactant composition as described in hydrocarbon recovery operations associated with oil/tar sand, where such fluids act to increase the dispersant qualities of hydrocarbons within the oil/tar sand, and where such fluid exhibit a reduced coefficient of friction. |
