... properties and completion design but with different cluster and stage spacing were analyzed to validate the observed signatures. The conceptual numerical model results show that the wells at wider cluster spacing (and longer stage length) exhibit longer linear flow duration, which does not necessarily...

... for unconventional reservoirs. It uses a simulation model of the reservoir and has been applied to transient linear flow, the predominant flow regime of unconventional wells. The transient linear flow IPR resulted in curves with shapes that are very different from the conventional IPRs. These unexpected shapes were...

... transient may extend to many hours or days, or may never appear. This paper introduces a new model showing that miscible fluid injection produces a linear flow response in the early BC DFIT falloff transient that is easily recognized on a Bourdet log-log diagnostic plot as a pressure derivative trend with 1...
