Mr. Charles Laser, former President of the private company that formerly managed Landsat Satellite Imaging, made the discovery of the Thronburg Oil and Gas Field. Landsat products are used on a regular basis, to conduct geological surveys for oil, gas and minerals. According to Laser, the Thronburg Ranch, comprising of 1,000 acres, is a likely substantial oil discovery. Well No.-1 drilled on the low portion of the anticline encountered excellent oil indications below the oil water contact. This means that a very substantial amount of hydrocarbons exist under the Thronburg Ranch, which could exceed 10 million barrels of oil.
The No.-l Thronburg well was drilled to evaluate a prospective fault trap interpreted from photo-geology and surface mapping. The following information is extracted from an engineering report made by Mr. George J. (Joe) Kirn, #5588, member of the American Association of Petroleum Geologists, and a registered professional geologist in the state of Wyoming #PG 2710 regarding Thronburg Oil Well Number 1: The well was located in the proximity of the up dip bounding fault on the southwestern side of the prospective fault closure. The well encountered excellent indications of live oil in all porous intervals of the phosphoria formation. Two intervals were perforated. The uppermost interval produced sulfur water with a slight rainbow of oil and a lower interval produced some black, tarry, heavy oil. The combination of very good oil indications and recovery of water indicates that the well is structurally down-dip from the oil-water contact. The oil productive area of the prospect will be at a structurally higher position above the oil-water contact, perhaps only 50-100 ft. higher that the No. 1 Thronburg. Thronburg Ranch is located on the south flank of the Big Horn Basin in Township 8, North, Range 4 East, Wind River Survey, approximately 10 miles from Thermopolis, Wyoming. The nearest oil production is at King Dome approximately 6 miles North and at Hamilton Dome, located 9.5 miles to the Northwest.
