... Abstract There are many examples of dry oil production from portions of reservoirs where the local water saturation is high. When relative permeability data are available, predictions of the expected water cut are not zero, but typically 30-60%. This lack of agreement means that reservoir...

... (typically 0-5%) would give rise to the high levels of irreducible water saturation. Nor does it explain why the low resistivity zone is observed to have a finite thickness in a number of wells where the logs extend below the OWC. The EPT, run in an OBM environment is valuable in this context as a geological...
