SLIP-LAYER FLUID PLACEMENT |
摘要 |
A method of fluid placement in a hydraulic fracture created in a subterranean formation penetrated by a wellbore that comprises the use of one or more reactants that form a low friction layer between the fluids that penetrate the fracture in consecutive treatment stages. Reactants can be added to the fluid that is the carrier or other fluid to be placed in a specific region of the fracture, namely as an upper or lower boundary of the fracture, or added to both the stage that requires placement in a specific section of the fracture and in the stage preceding it, especially the pad and carrier fluids used in consecutive stages. |
