... Technology Historically, the development of tight gas reservoirs has involved drilling vertical wells and hydraulically fracturing them, often with the use of large amounts of proppant. These large fracs are known as massive hydraulic fracs (MHF) and typically involved hundreds of thousands or even millions...
