The technology of horizontal drilling has become a key method applied to the arsenal of the oil industry over the past 10 to 12 years. A particular increase of developments among equipment, techniques, and economically driven efficiency requirements has caused widespread consideration and testing of this technology. In many basins and reservoirs, properly applied horizontal drilling technology has demonstrated an incremental advantage over vertical wells. Virtually all relevant trade journals have carried articles over the past 5 years expressing considerable optimism as to the business growth prospects of horizontal drilling. So far, these predictions appear to be valid. A close student of the subject, David Yard, estimated in January 1990, that horizontal completions would escalate by 230 percent annually, and that more than 2,000 successful completions could be expected in 1992. He also expected lifting costs to fall into the $4- to $6-per-barrel range. The tubing’s wall thickness, on the order of 0.05 to 0.2 inches, is considerably less than that of drill pipe, which ranges from about 0.2 inches to about 0.5 inches. Its diameter is also less, on the order of ¾ to 2 inches, whereas drill pipe ranges from about 2 inches to about 5½ inches in diameter. The smaller dimensionality, as well as the use of different alloys, renders the tubing much more flexible than standard drill pipe, at the expense of increased fragility and decreased l load handling capabilities in both compression and tension. In horizontal use, the
