MWD
During the 1970s while GO was developing other new technologies and breaking into markets, which included Venezuela, Africa, and the North Sea, the domestic oil and gas business was starting to escalate. With a fleet of wireline units that now numbered in the hundreds, Gearhart continued to branch out and had visions of a company that offered a complete package. GO wanted to offer energy producers a line of services that included wireline services, perforating, drilling services, core analysis, seismic services and so on. Fort Worth had now become a research and development center. Gearhart researchers were concentrating on a new technology called Measure While Drilling (MWD). This new product was being developed for market by the same team that had given life to DDL earlier. MWD was what made controlled directional horizontal drilling possible. MWD saved time and money over the traditional methods of wireline logging by eliminating the wireline. After a few years of testing, both Gearhart and its Canadian affiliate Computalog were gaining advances over their competition.
