Abstract
Official abstract text for this publication.
A method is given for treating a wellbore in a subterranean formation by hydraulic fracturing, slickwater fracturing, gravel packing, and the like, by using plate-like materials as some or all of the proppant or gravel. The plate-like materials are particularly useful in complex fracture systems, for example in shales. They may be used as from about 20 to about 100% of the proppant. Relative to conventional proppants, plate-like proppants demonstrate (a) enhanced crush resistance of the proppant due to better stress distribution among proppant particles, (b) diminished proppant embedment into formation fracture faces due to the greater contact surface area of proppant particles with the formation, (c) better proppant transport due to lower proppant settling rates, (d) deeper penetration into branched and fine fracture networks, and (e) enhanced proppant flowback control. Preferred plate-like proppants are layered rocks and minerals; most preferred is mica.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of treating a subterranean formation penetrated by a wellbore comprising: preparing a slurry of a proppant; injecting the slurry down the wellbore; and maintaining the proppant in fractures formed in the subterranean formation, wherein the proppant comprises at least about 50% by weight of plate-like particles having a thickness of from about 1 to about 500 microns and a particle aspect ratio of at least 5; wherein the plate-like particles…
