OSTI ID:5146706
The study is based on analysis of the geologic setting and petrophysical and production characteristics of the Upper Cretaceous Big Wells (San Miguel) wave-dominated deltaic reservoir. Diagenetic overprint and a weak drive mechanism are major causes of poor recovery from the Big Wells pool. The principal concern was to determine whether reservoir heterogeneities further hindered production and trapped conventionally recoverable oil in isolated compartments in the reservoir. The authors found that well-to-well heterogeneity has played a minor role in affecting oil production from the reservoir. Rather, fieldwide variability exerts a strong influence on oil recovery. The authors conclude that wave-dominated deltaic reservoirs are characterized by minimal well-to-well heterogeneity, excellent internal strike continuity, and, consequently, maximum efficiency of mobil-oil recovery.
