Theory, methods of application and results of the use of 100 mesh sand in stimulating Permian Basin formations
The basic method of application is to hydraulically initiate or fracture into the formation with a pad fluid. Then, a slurry of 100 mesh sand is introduced which effectively reduces leakoff through any intersecting hairline cracks which are encountered. The 100 mesh does not restrict fluid travel down the principal fracture, and thus allows the subsequent fracturing fluid to extend the principal fracture to the desired distance into the reservoir. Once this hydraulic control is established, the principal fracture can then be propped with larger frac sands, or the fracture faces of a carbonate rock can be etched with acid just as they are in conventional treatments. Therefore, this particular use of 100 mesh sand is primarily as an added conditioning step in the pad fluids of a stimulation treatment. In partially depleted zones which have been heavily acidized, it is necessary to use large volumes of 100 mesh sand in order to fill all the previously created voids so that the new treatment can enter previously untreated portions of the zone.
