METHOD OF TREATING A SUBTERRANEAN FORMATION

摘要

A method of treating a subterranean formation, involving performing a fracturing operation and performing a shut in. At a time before or after the shut in is commenced, changes in properties at or near a fracture are estimated based upon monitored data. A plugging agent is injected taking into consideration the estimated changes in properties.

1. A method of treating a subterranean formation penetrated by a wellbore comprising:
performing a fracturing operation by introducing a treatment fluid into the wellbore at a fluid pressure equal to or greater than a fracture initiation pressure of the subterranean formation to induce a fracture in the subterranean formation; estimating changes in fracture geometry by monitoring data from one or more sensors while the fracture is open; performing a shut-in by stopping injection of the treatment fluid; and introducing a plugging agent, after performing the shut-in, plugging the induced fracture; wherein the plugging agent is introduced after a period of time, the period of time being determined based upon the monitored data.
