摘要： 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%.

摘要： An extrusion method and apparatus are described for producing ceramics, glass, glass-ceramics, or composites suitable for use as proppants. The method includes forming one or more green body materials, extruding the green body materials to form a green body extrudate, separating and shaping the green body extrudate into individual green bodies, and sintering the green bodies to form proppants. The apparatus includes a means for forming an intimate mixture of green body materials, means to produce a green body extrudate, means for separating and shaping the green body extrudate into individual green bodies, and means to sinter the green green bodies to form proppants.
