Largest Oil and Gas Basin

Horton Draw Prospect is located in the Bighorn Basin the largest oil producing basin in the Rockies with 2.6 Billion Barrels production to date with over 32 producing fields in the basin.

Regional Geography

The Bighorn Basin is a plateau region and intermountain basin, approximately 100 miles (160 km) wide, in north-central Wyoming in the United States. It is bounded by the Absaroka Range on the west, the Bighorn Mountains on the east, and the Owl Creek Mountains and Bridger Mountains on the south. It is drained to the north by tributaries of the Bighorn River, which enters the basin from the south, through a gap between the Owl Creek and Bridger Mountains, as the Wind River, and becomes the Bighorn as it enters the basin. The region is semi-arid, receiving only 6-10 in (15–25 cm) of rain annually.

The Big Horn Basin is a splendid place to find the old west, as well as the eastern gateway to Yellowstone. The region’s open landscapes have a vigorous beauty framed by five mountain ranges.  Much of the Basin’s intrigue comes from its complex blend of western stories told through geology, paleontology, Native American and Old West history, and a traditional western way of life.

Horton Draw Prospect

Horton Draw is located approximately ten miles south of Ten Sleep Wyoming in the Bighorn Basin Horton Draw bitmapof Wyoming, the largest oil producing basin in the Rockies with 2.6 Billion Bbl production to date. Located in a well-known oil and gas producing region, there are approximately 12 production fields in this area including the Cottonwood field to the north, the Enigma field to the west and the Wilde Horse fields to the south.  Other O&G leaders are involved in same area such as Koch Industries, a leading U.S.A. private oil and gas development company. Koch Industries recently acquired the rights to develop the property immediately adjacent to our prospect to the north and is in the process of conducting 3D seismic studies that tie into the Horton Draw prospect.

Area Geology 

In the Ten Sleep area of the basin there is a well-known geological feature named the Bud Kimball anticline that trends from NW to SE running through the heart of the Horton Draw prospect. This surface anticline is gently plunging to the NW and appears to line up with the producing structures at Bonanza, Nowood, and Manderson oil fields.



From a Seismic Perspective

Line OJ-1 showing various structural features

Both the Tensleep hanging wall anticline and the Tensleep footwall trap structures present in this prospect create additional possibilities.  The seismic data  confirms the presence of a large anticline  present at the Tensleep level.  Similar to the many other anticlines in the Bighorn Basin, this could be a very large oil accumulation at a depth of only 3000’.

This area shows some different structural styles than the rest of the basin.  This type of feature is known to produce in many other basins all over the world, so it has merit in this area as well.    Actually, the overall appearance of this key dip line is similar structure in Oklahoma in the Carter-Knox field area.  In that instance there is a thin-skinned thrust fault feature on the hanging wall there that was found to be productive in the 1920s but immediately east of that obvious anticline is a deeper feature bounded by high angle faults that wasn’t discovered until the 1990’s.
