Description
Summary:The mathematical procedure for locating hydrodynamic traps can be combined into a single computer program that will draw new oil potential contours for a variety of postulated water flow conditions. A mapping program call SURFER is used in this case to calculate oil potentials using Hubbert's equation directly from known structural and water potential data, and to draw the contours automatically. The method is applied to Sage Creek field, a known hydrodynamic trap in the Big Horn Basin in northwest Wyoming and it is shown that hydrodynamics alone can not trap the oil accumulation in this structure. It is suggested that the trapping mechanism in this field is a function of reservoir heterogeneities associated with a strong hydrodynamic gradient.
