HISTORY

The Tulsa Timeline

In 1925, Amerada® Petroleum Corporation created Geophysical Research Corporation to investigate the possibility of applying geophysical methods to oil exploration. This idea soon came to fruition when a team of scientists led by Charles Milikan 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.

The Amerada® Gauge offered pressure data not previously available to oil companies, so the product was quickly in high demand. It long remained the pressure standard of the industry, preferred by private oil companies and state, provincial, and national governments requiring pressure reservoir data.

GRC became an independent company in 1971, when it was purchased by a group of Tulsa businessmen. In January 2012, Sercel S.A. acquired the assets of GRC with a strategy and commitment to coupling the highest-quality and most innovative downhole sensors. Since the conception of Geophysical Research Corporation, the company has maintained its technological leadership in the industry, continuously improving and innovating our products, services and support with one goal in mind:  to satisfy our customers.

With a reputation as the largest independent gauge manufacturer, our facility boasts 35,000 ESP gauges and 2,200 Spy Pro ESP gauges. To date, GRC has built 130,000 gauges total!
