The Tensleep Sandstone and Madison carbonate reservoirs at Wertz and Lost Soldier fields, southern Wyoming, were the subject of a fracture distribution study as part of a tertiary development study. A fracture classification scheme for the reservoirs was developed, and foot-by-foot fracture description of 15 cores throughout the two fields were generated. The core fracture classifications and descriptions were digitized for computer use. A computer-generated second-derivative map of the Tensleep structure accurately reflected fracture distribution as described from cores in both the sandstone and carbonate reservoirs. Computer-generated crossplots of number of fractures per foot versus a variety of petrophysical rock parameters identified structural position and lithology as the key factors governing fracture distribution and intensity in the Tensleep and Madison reservoirs.
