HIGH-STRENGTH, LOW SPECIFIC GRAVITY, FRACTURING BALLS

摘要

A fracturing ball comprises: a metal or a metal alloy, wherein the fracturing ball is a shell having an outer diameter and an inner diameter, wherein the fracturing ball has a desired specific gravity less than or equal to a necessary specific gravity such that the ball flows to a wellhead of the wellbore after a desired amount of time, and wherein after engagement of the fracturing ball with a baffle, fluid is prevented from flowing across the ball. A method of creating one or more fractures in a zone of a subterranean formation comprises: (A) introducing the fracturing ball into a tubing string of a wellbore; (B) causing or allowing the ball to engage the baffle; (C) creating the one or more fractures in the zone of the subterranean formation; and (D) producing a reservoir fluid from the zone of the subterranean formation.
