Using Channel Morphometrics and MPS to Improve Reservoir Model Accuracy: an example from Greater Monument Butte Field, Uinta Basin Utah

Reservoir characterization focuses on rock and fluid properties, and how they vary about a field. Often engineers and geologists spend little time characterizing the size and arrangement of reservoir bodies which can be critical to accurately modeling fluid flow. In the Greater Monument Butte Field, oil is primarily produced from lacustrine-deltaic channel sand-bodies. In the field, channel characteristics were estimated using core, wireline logs, outcrop, and modern analogs, and were used to make realistic representations of channel thicknesses, widths, and sinuosity. These images were used to train muti-point statistical (MPS) realizations of reservoir facies. Accurate facies realizations decreased the uncertainty about connectivity between injectors and producers, and provided the basis for potential in-fill drilling in some parts of the reservoir.
