Abstract: Hydraulic fracturing of subterranean formations has become more complex and detailed as information increases. Methods for calculating and monitoring reservoir pressures during treatment provide unique opportunities to adjust treatments on the fly. Treatments include acid fracturing, fracture acidizing, acid stimulation, propped acid fracture stimulation, hydraulic fracturing, slick water based hydraulic fracturing, foamed based hydraulic fracturing, foam based acid fracturing, foamed based acid diversion, any other physical particulate and fiber based hydraulic fracturing or matrix treatment.

Abstract: Reducing leak-off during acid stimulation with dissolvable material sized to preferentially block crevices and wormholes, thus allowing the acid to travel further down the fractures, etching deeper into the reservoir than a similar process not using such dissolvable materials. After stimulation, the materials dissolve and production can proceed and will be improved over what is possible without such dissolvable materials.
