Abstract: Identification Of Bypassed Pay Through Log/Core Integration
Abstract
This paper presents a cost-effective, quantitative method for the identification of bypassed pay zones through a better understanding of various pore geometries found in the reservoir and their effect on saturation distribution and the type of fluid production. The method used is based on identification of various pore geometries (rock type), integration of the “rock type” model with relative permeability and capillary pressure characteristics, and prediction of water cut for each flow unit identified in the field.
When the “pore type” model is combined with wireline log data, prediction of rock types and resultant petrophysical properties can be made. These data can then be extrapolated to intervals in non-cored wells to evaluate the potential of bypassed pay. Examples are given to demonstrate that this unique technique for improved reservoir characterization has provided a means of targeting intervals with additional pay potential.
