From drawing board to drill string
This article explains that justification for a new downhole tool typically involves maintaining performance at reduced costs or increasing performance. Some new tool concepts are derived from a management decision to replace or improve old or obsolete equipment. The newer models typically have increased performance ratings and are better suited to meet the growing downhole needs of modern drilling. A new tool will usually fill one or some combination of three roles: providing services that were previously not available; complimenting and increasing usage of an existing tool; and, expanding operations into a new field of service. One of the more fundamental trends affecting development of virtually all downhole tools is increased average depth per well. The deeper wells require tools and materials that will withstand higher pressures and temperature and more corrosive environments.
