Method of fracturing subterranean strata
Patent
·
OSTI ID:5922328
A method or process for fracturing and propping a subterranean stratum to provide high permeability for the flow of oil through the fracture is described. The subterranean stratum is fractured with a suitable fracturing fluid through a well penetrating the stratum. This is followed by injecting sequentially into alternate segmental portions of the fracture around the well, a permanent propping agent and a temporary (fluidizable) propping agent. Thereafter, the temporary propping agent is fluidized and rendered ineffective as a propping agent to provide improved flow paths for fluids through the fracture. (11 claims)
