In 1925, Amerada® Petroleum Corporation created Geophysical Research Corporation to investigate the possibility of applying geophysical methods to oil exploration. This effort was soon rewarded, when a team of scientists led by Charles Miliken developed a mechanical tool to measure downhole pressure and temperature. This tool, known as the Amerada® Gauge, enabled reservoir engineers and geophysicists to determine wellbore and reservoir capacity and performance.
Since the Amerada® Gauge offered precise pressure data, which was not previously available, other oil companies immediately demanded the technology. The Amerada® Gauge long remained the pressure standard of the industry, preferred by private oil companies and state, provincial, and national governments that required pressure reservoir data.
In recognition of this breakthrough technology’s historical significance, the Smithsonian Institution now displays GRC’s first downhole pressure gauge (dubbed the “Amerada® Bomb”).
In the years since the company’s founding, GRC has maintained its technological leadership in the industry. Continued investments in research and development have led to innovative solutions that enhance reliability, data accuracy and resolution, and a wide range of customer-specific applications. In recent years, GRC innovations in transducer technology (Quartz and Gap Capacitance) have proved vital in permanent, memory and artificial lift applications.
Today GRC offers a full line of technology to assist production operation and reservoir engineers around the world. The company’s reputation for innovation and services are known the world over.
Geophysical Research Corporation became an independent company in 1971 as a result of its purchase by a group of Tulsa businessmen. In January of 2012, Sercel S.A. acquired the assets of GRC, with a strategy and commitment to coupling the highest-quality and most innovative downhole sensors with the best in customer service.
