This paper presents an overview of geologic factors that influence initial reservoir analysis and performance prediction at Anschutz Ranch East. In early stages of development, gross structural interpretation and the prediction of reservoir size and orientation is paramount. As development proceeds, geologic input becomes more specialized to include small-scale structural, stratigraphic, and diagenetic factors. At Anschutz Ranch East, pressure maintenance must be instituted before any retrograde condensate is produced. Therefore, geologic data normally associated with secondary recovery studies are in this case needed for initial reservoir development. Because reservoir pressure is so close to the dewpoint pressure, the field is essentially shut-in until pressure maintenance in the form of hydrocarbon gas and nitrogen injection is begun. Currently, the working interest owners, including Amoco Production Co., The Anschutz Corp., Champlin Petroleum, BWAB Inc., Tom Brown Inc., Mesa Petroleum Co., and Gulf Oil Exploration and Production Co., are collaborating to form a development unit. Amoco Production Co. will be the major interest holder and the field operator.
