Multilayer propping of fractures
Patent
·
OSTI ID:6856514
This is a method of increasing the permeability of formations by the creation of highly permeable vertical fractures. Thin, alternate layers of at least 2 layers of an insoluble, solid, particle-form material and at least 2 layers of a soluble, solid, particle-form material are deposited in a vertical fracture. Following such deposition, the soluble material is removed from the fracture by the solvent action of the fluids being produced, or by the injection of extraneous fluids which will act as a solvent. Accordingly, the vertical fracture will be propped open by a number of horizontal bridges of insoluble material with alternate void spaces between. The alternate layers of soluble and insoluble particles may be deposited by flotation or gravity setting or both.
