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 18):
The method of  claim 16 , wherein at least one of the following conditions prevail:\n (a) the first fluid and the second fluid contain the same breaker and further wherein the amount of breaker in the second fluid is more than the amount of breaker in the first fluid; (b) the first fluid and the second fluid contain the same gel stabilizer and further wherein the amount of gel stabilizer in the second fluid is less than the amount of gel stabilizer in the first fluid; (c) the second fluid is less stable than the first fluid by the amount of pH buffer present in the second fluid; or (d) the first fluid and the second fluid contain the same viscosifying agent and wherein the amount of viscosifying agent in the second fluid is less than the amount of viscosifying agent in the first fluid.
