Gearhart Industries

Gearhart Industries, also known as The GO Company and formerly associated with the names GO Oil Well Services and Gearhart-Owen Industries, was an oilfield-services company founded in 1955 by Marvin Gearhart and Harrold Owen. Based in Fort Worth, Texas, the company served the petroleum industry through specialized services performed on oil and gas wells. Its principal activities were well logging and well perforating. Well logging involves collecting subsurface measurements and other geological or engineering data from a borehole, helping operators evaluate formations and make decisions about drilling and production. Well perforating is a completion operation in which selected sections of a well casing are opened to establish communication between the wellbore and productive formations. These activities placed Gearhart within the technical service segment of the oil and gas industry rather than in exploration, refining, or retail fuel distribution. The company supplied services to both domestic and international customers, indicating that its business was not limited to the United States. Its development reflected the growing importance of specialized measurement and completion capabilities in petroleum operations, where service companies provide equipment, field expertise, and technical support to drilling and production operators. A major turning point came in February 1988, when Gearhart announced that it had entered into a buyout agreement with Halliburton Company, one of the largest oilfield-service companies. Following the transaction, Gearhart was combined within Halliburton with Welex Jet Services. The resulting operation became Halliburton Logging Services, ending Gearhart Industries as an independent company and transferring its well-logging and related service activities into Halliburton's organizational structure. Because the available reference material is limited, detailed information about Gearhart's later corporate structure, financial performance, leadership succession, product brands, and individual international operations is not established here. The company's documented historical significance lies primarily in its role as a specialized well-logging and well-perforating provider and in its absorption into Halliburton's logging-services business.

Gearhart Industries was established in 1955 by Marvin Gearhart and Harrold Owen. The company operated from Fort Worth, Texas, and developed a business serving oil and gas operators with specialized well services. It was also identified by the names The GO Company, GO Oil Well Services, and Gearhart-Owen Industries, reflecting changes or variants in its corporate identity over time. The company's documented service scope centered on well logging and well perforating. These are technical operations carried out during the drilling and completion lifecycle of a petroleum well. Logging supplies information about formations and well conditions, while perforating enables selected producing zones to connect with the wellbore. Gearhart therefore occupied a specialist position within the oilfield-services sector, supporting operators rather than producing crude oil or natural gas itself. Gearhart served both domestic and international customers. The available historical account does not provide a complete list of countries, regional offices, major contracts, or financial results, so the scale and geographical composition of its international business cannot be specified reliably. Similarly, detailed information about its equipment portfolio, proprietary technologies, and executive succession is not established by the cited material. On February 24, 1988, Gearhart announced that it was entering into a buyout agreement with Halliburton Company. Halliburton subsequently combined Gearhart with Welex Jet Services. The combined activity became Halliburton Logging Services, bringing Gearhart's documented operating capabilities into Halliburton's logging-services organization. This integration ended Gearhart Industries' existence as an independent company and explains its present classification as a defunct brand or company rather than an active standalone provider. The surviving record presents Gearhart primarily as a historical oilfield-services company whose importance came from its well-logging and well-perforating work and its eventual incorporation into a major international oilfield-services group. Further archival research would be required to document its full corporate chronology, technology development, market share, leadership, and post-acquisition brand treatment.

• Well logging servicesOilfield services

  Gearhart provided well-logging services for oil and gas customers. These services generate subsurface and borehole information used to evaluate geological formations, assess well conditions, and support drilling or production decisions. The available references identify logging as one of the company's core activities, but do not specify the particular logging instruments, measurement technologies, product names, or service packages it offered.

• Well perforating servicesOilfield services

  Well perforating was another principal Gearhart service. Perforating creates openings through well casing and cement at selected intervals so that hydrocarbons can flow between a productive formation and the wellbore. Gearhart supplied this completion-related capability to domestic and international petroleum operators. Specific perforating tools, operating procedures, and commercial service brands are not identified in the available source material.
