Evolution of Filtration Pressure Waves in a Hydraulic Fracture during Transient-Well-Operation Modes

At present, a significant part of oil is extracted from difficult-to-develop reservoirs with low permeability. Hydraulic fracturing one the most important methods production stimulation. Scientific articles do not describe connections between flow-rate in well and change pressure hydraulic fracture or changing fracture, except some cases constant fluid-flow production. We obtained both exact analytical solutions simple approximate which connection well-fluid evolution fracture. The work has also solved inverse problem: how to determine parameters knowing fluid-flow. results show good comparison practical data.
