Patent number: 10161236Abstract: Methods of fracturing a subterranean formation are described wherein sintered ceramic proppants are used in at least two different stages. Each stage can utilize the same or a different type of proppant relative to one or more of the other stages, and the same or a different type of fracturing fluid relative to one or more of the other stages. At least one of the stages uses a proppant having a monodispersity of 3-sigma distribution or lower. A first stage can be used that exhibits at least one proppant performance property having a first value. A second stage can be used that exhibits the same proppant performance property as the first stage but at a value that differs from the first value by at least 10%.Type: GrantFiled: April 22, 2014Date of Patent: December 25, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Robert D. Skala, Christopher Y. Fang, Christopher E. Coker
