Petro River Oil Corp. announced that it will spud the Cattani-Rennie 47X-15 exploration well (the “CR 47X”) in the Sunset Boulevard prospect in Kern County, California this week. The CR 47X will be the first well drilled by Petro River and its partners in the Sunset Boulevard prospect based on recently acquired 3-D seismic, which has identified several prospects in the Kern County field. The Kern County field has potential prospective resources totaling up to 50 million barrels of oil in multiple pay zone opportunities. The CR 47X well will cost approximately $2 million and will be drilled to a depth of 9,000 feet. The CR 47X will test both the upper Miocene development opportunity and sub-trust Jewett and Vedder sandstone targets. Initial results are expected in approximately 30 days.
