... forecast without any costly PVT and pressure history data. Moreover, a set of diagnostic plots has been developed to identify the degree of the blockage to the gas production from the near wellbore oil-bank. This new methodology has been tested on more than one hundred horizontal wells that have been...

... diagnostic plots that have been improved by incorporating important concepts such as MBT, pseudo-variables (for gas wells) and pressure-normalized rates. Each DCA model has been designed assuming specific flow regimes. Therefore, a proper identification of dominant flow regimes will help us to perform...

... plays such as the Eagle Ford. Contrary to the assumption that these wells were still in linear flow, we found evidence from diagnostic plots that many horizontal wells in the Elm Coulee that began producing in 2006 and 2007 have entered boundary-dominated flow. In order to accommodate boundary flow we...

... in this field. Analysis shows that water production behavior in this field is neither related to permeability distribution from core analysis nor to the distance from the bottom of perforation to gas-water contact. Diagnostic plots of the Cartesian derivative of water-gas ratio versus time have shown promise...
