Abstract:
A method of enhancing conductivity within a hydrocarbon-bearing reservoir by building proppant pillars in a spatial arrangement in fractures created or enlarged in the reservoir. Two fluids of differing stability are simultaneously pumped into the reservoir. The fluids may contain identical proppant mixtures which include a first proppant which has an apparent specific gravity less than the apparent specific gravity of a second proppant. The fluids may contain identical proppants mixtures where the average particle size of a first proppant is greater than the average particle size of a second proppant. Vertically extending pillars are created within the formation when the fluids are destabilized and the first proppant is then released from the destabilized fluids. The area between the pillars may be held open by the presence of the second proppant in the remaining fluid. Fluid produced from the hydrocarbon-bearing reservoir is then flowed at least partially through channels between the vertically extending pillars.

Claim (Index 1):
A method of enhancing the productivity of hydrocarbons from a hydrocarbon-bearing formation which comprises:\n (A) subsequent to creating or enlarging one or more fractures within the subterranean formation, simultaneously pumping into a well penetrating the hydrocarbon-bearing formation a first fluid and a second fluid wherein the first fluid is more stable than the second fluid and further wherein:\n (i) the first fluid and second fluid contain the same proppant mixture comprising a first proppant and a second proppant wherein (i) the first proppant has an apparent specific gravity greater than the apparent specific gravity of the second proppant; and/or (ii) the average particle size of the first proppant is greater than the average particle size of the second proppant; and \n (ii) the first fluid has a volumetric mass density greater than the volumetric mass density of the second fluid or the first fluid is more viscous than the second fluid; \n (B) degrading the second fluid and releasing the first proppant from the second fluid; (C) consolidating the released first proppant from the second fluid on an upper portion of the first fluid and/or at a pinch point in the width of the fracture; (D) introducing the released first proppant from the second fluid into the width of the fracture and creating at least two pillars within the fracture from the released proppant; (E) degrading the first fluid and releasing the first proppant from the first fluid onto the created pillars; and (F) creating a channel in the subterranean formation between pillars with the second proppant in the first fluid and the second fluid.
