Arnie Ostrander is a non-seismic oil and gas exploration consultant and researcher. His early research work with Exxon, Marathon, Texaco, and other major oil companies and some smaller independents demonstrated the potential of using non-seismic resistivity technology for oil exploration in plays where seismic data does not delineate the oil and gas reservoirs. Arnie's 40-year focus has been the utilization of non-seismic geophysical methods for the delineation of high-volume, high­ profit, and underdeveloped fracture reservoirs, and some potentially high-volume stratigraphic reservoirs that were not observed in either 2-D or 3-D seismic data.
