摘要： A method of fracturing a subterranean formation to produce fluid from a reservoir through a wellbore includes flowing a treating fluid into the wellbore to create fractures in the formation, selectively flowing a flow constraint material (FCM) into the wellbore simultaneously with the treating fluid, pausing the flow of the FCM while maintaining the flow of the treating fluid, monitoring a parameter of the formation to determine whether the parameter is within a range, resuming the flow of the FCM when the parameter of the formation is out of the range, ceasing the flow of the FCM when the parameter of the formation is in the range, where a system strain increase is about 0.0003 or less when the parameter of the formation is in range, and where the flow of the flow constraint material partially constrains the treating fluid from entering at least one of the fractures.

摘要： A flow constraint material consists essentially of degradable particles, where at least 50% by volume of the degradable particles have an average particle size of about 1 millimeters (mm) to about 6 mm.
