Methods of Enhancing Fracture Conductivity of Subterranean Formations Propped with Cement Packs

摘要

Methods of treating a subterranean formation including providing a wellbore in a subterranean formation having at least one fracture; providing an expandable cementitious material; introducing the expandable cementitious material into the at least one fracture in the subterranean formation; curing the expandable cementitious material so as to form a cement pack, wherein the curing of the expandable cementitious material expands the expandable cementitious material such that at least one microfracture is created within the at least one fracture in the subterranean formation; and acid-fracturing the at least one fracture in the subterranean formation.
