A steam drilling rig has been used to drill a well to 23,157 ft in southern Louisiana, 3 miles W. of Kaplan in Vermilion Parish. One major factor in well cost reduction was the decision to go all the way with water-base mud, spotting or displacing with an oil-base mud when necessary to free stuck pipe, and to minimize that danger by use of spiral collars through zones of likely trouble. Drilling of the well was a 5-stage operation involving 2,450 ft of 18-in. hole, 9,681 ft of 12-1/4-in. hole, 5,341 ft of 8-5/8-in. hole, 3,932 ft of 6-1/8-in., and 2,744 ft of 4-1/8-in. hole. Electric logging is complicated by high pressures and temperatures; however, 14 logs were successfully run. The well was completed with 2 casing strings and 2 liners. Four intervals were perforated and drill-stem tested by Halliburton, and a tapered tubing string was run to the top of the perforation of the special high-temperature production packer. The perforated interval was treated with diesel oil and a high flow macaroni string was installed inside the production tubing. A special high-pressure Christmas tree had to be constructed and installed to withstand wellhead pressure up to 20,000 psi and severe corrosive environments.
