New tools allow medium-radius horizontal drilling
ARCO Oil and Gas Co. (AOGC) recently completed a project to develop new methods of drilling conventional-sized horizontal holes. A well bore of this type is particularly well-suited for producing low-permeability, fractured reservoirs at economic rates. Special drilling tools and support equipment were developed jointly with several major manufacturers. Of these tools, one of the systems developed with Norton Christensen most nearly met the design goals. This system was tested in Rockwall County, Tex., where a 6-in. OD horizontal hole was successfully drilled in the Austin chalk formation. The build rate from vertical to horizontal was 20/sup 0//100 ft; the horizontal portion of the well bore was drilled for another 1,340 ft. This gave a total horizontal displacement of 1,630 ft. The horizontal well bore was kept within a 30-ft vertical section.
