This is a report from 2000 about the bastrop zone, titan oil and gas currently has 250 acres with an additional 350 acres as an option, back in 1999-2000 it wasnt economic for stanton mineral development to go after it at $30 per barrel, but now in 2006, titan oil and gas has leases there and its $65 per barrel, if they can get to these underground resevoirs..........O Boy

Well drilling and completion costs throughout the U.S. are too high for many marginal prospects to be economical. The situation at Oak Hill Field - a domal structure located over an igneous rock mass intruded in the subsurface in Bastrop County, Texas - is typical, the reservoir is likely to be less than 200 acres, and is at a drilling depth of 3,800 feet. Production from such fields has produced more than a hundred million barrels since the 1920's. However, most of the fields being discovered or produced in the region today are smaller and deeper, leaving as much as two hundred million barrels of marginal or uneconomic reserves in numerous known reservoirs, and potentially many others yet undiscovered, all of which can be produced provided alternative drilling and completion technologies can lower the cost of development and production. Stanton expects to reduce well costs at the Oak Hill Field by 30 to 50 percent by using slimhole technology. Maurer Engineering Inc. will act as consultant on the project and will assist in planning and drilling the slimholes. A 6 -inch exploration well will be drilled and 3 -inch tubing cemented in as casing if the well is successful. The hole will be drilled using conventional motors or, if possible, new high-powered positive displacement motors developed for DOE by Mauer. These high-power DOE slimhole motors drill 2 to 3 times faster than rotary drills and produce less wear and tear on the drillstring, the pipes that hold the drill bit. On later wells, the compact, economical coiled tubing technology may be used for completion and production. If this project is successful, slimholes could have widespread application in all areas of the United States where low-productivity oil and gas wells are drilled. Up to 300 barrels of oil per day, and 20 million cubic feet of gas per day can be produced through 3-inch tubing, so slimholes could be used in a majority of producing areas today.
