Developing low permeability reservoirs is currently a big challenge to the industry. Because low permeability reservoirs are of low quality and are easily damaged, production from a single well is low, and there is unlikely to be any primary recovery. Therefore, in most cases, unconventional recovery methods are used for economic development of those reservoirs. Hydraulic fracturing has been an important...
Produced water in oil field is generally recycled back to the formation, and the dynamic analysis of formation pressure during water injection has always been a research hotspot. It is difficult, however, to apply current numerical models to formation pressures analysis during water injections due to the models' complexity. Furthermore, actual formation conditions are quite different from the generic...
