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%.

Methods for fracturing subterranean formations

Synthetic ceramic proppants are described. Methods to make these proppants and methods of using these proppants are also described.

Proppants and methods of making the same

Synthetic ceramic proppants are described. Proppants having a monodispersity of 3-sigma distribution or lower are also described, including methods to make these proppants and methods of using these proppants.

Synthetic proppants and monodispersed proppants and methods of making the same

Methods are described to make strong, tough, and lightweight whisker-reinforced glass-ceramic composites through a self-toughening structure generated by viscous reaction sintering of a complex mixture of oxides. The present invention further relates to strong, tough, and lightweight glass-ceramic composites that can be used as proppants and for other uses.

Self-toughened high-strength proppant and methods of making same

A proppant having low surface friction is described, which is useful in hydrocarbon recovery. Methods of making low surface friction proppants are further described, as well as uses thereof.

Low surface friction proppants

The present invention relates to glass-ceramic proppants which can be used to prop open subterranean formation fractions, as well as other uses. Proppant formulations are further disclosed which use one or more proppants of the present invention. Methods to prop open subterranean formation fractions are further disclosed. In addition, other uses for the proppants of the present invention are further disclosed, as well as methods of making the glass-ceramic proppants.
