MATRIX-FRACTURE INTERFACE CLEANUP METHOD FOR TIGHT SANDSTONE, CARBONATE, AND SHALE RESERVOIRS

摘要

The invention is related to a method to clean a matrix-fracture interface of fractured tight sandstone, tight carbonate, and tight shale reservoirs. The method involves the injection of at least one fluid into a reservoir, wherein the fluid is gas, a surfactant, a surfactant solution, or combinations thereof. In some embodiments, the reservoir has previously been stimulated mechanically by hydraulic fracturing.
