Formation fracturing
Patent
·
OSTI ID:6148648
A fracturing process is described in which a fracture formed in a formation is acid etched near the well and particle propped in the more remote portions of the fracture. A fracture is formed in the formation extending from the well and an acidizing fluid is injected into the fracture, in order to acid etch the walls thereof adjacent to the well. A carrier fluid containing propping agent is injected into the fracture. Subsequent to injection of the propping agent, a displacing fluid is injected into the fracture. The displacing fluid is introduced under conditions such that it displaces the previously injected propping agent away from the well into the more remote portions of the fracture. The displacing fluid may have a lower viscosity than the carrier fluid and may be injected at a greater rate than the carrier fluid. (1 claim)
