Free flowing oil was encountered in the top of the Ordovician, Knox Dolomite at 1636 feet. Drill cuttings analysis indicated intense natural fracturing and two overlapping fault zones with approximately 30 feet of throw. Technically SRPS and Natural Fracture Mapping were successful even though the well was completed as a dry hole. The well encountered 8 feet of oil saturation in the Granville Formation at a depth of 360 feet. Gas was encountered in an Upper Sunnybrook fracture zone at 425 feet.
Treatment is planned for the oil zone.
Our Radiometric Survey revealed significant potential in the northeast portion of the lease and two wells were drilled in January 1984 by Robo Enterprises of Bowling Green, Kentucky. Both wells were considered discovery wells and extended the Richardsville Field beyond previous boundaries. Based on our Natural Fracture Potential Maps the operator wanted to pinpoint and confirm the fractures before drilling. The well was sited directly on the fracture and drill cuttings indicated that the fracture was probably a minor fault with about 30 feet of vertical throw in the Murfeesboro formation. The well was dry but is considered a technical success because the SRPS did confirm and map the location of the fracture zone.
