Abstract:
1. In a computing system having a processor and system memory and which is configured to receive and analyze data relating to the areal displacement efficiency (E A ), vertical displacement efficiency (E I ), and pore displacement efficiency (E D ) of a petroleum reservoir, a method for determining a recovery deficiency indicator (RDI) for a petroleum reservoir, comprising: inputting into the computing system data relating to the areal displacement efficiency (E inputting into the computing system data relating to the vertical displacement efficiency (E inputting into the computing system data relating to the pore displacement efficiency (E the computing system determining, by relating together the areal displacement efficiency (E the computing system determining, based on at least the pore displacement efficiency (E the computing system determining, by relating the recovery efficiency (RE) with the ideal recovery efficiency (IRE), the recovery deficiency indicator (RDI) for the petroleum reservoir.
