Your Trusted Exclusive Equipment Supplier  & Broker in the Geophysical Industry

The R.T. Clark Companies, Inc., headquartered in Oklahoma City, Oklahoma, is a full-service multinational firm that serves the geophysical, geotechnical, engineering, and environmental communities.

Recognizing that the geophysical industry needed a channel for disposing of obsolete and excess equipment, the R.T. Clark Companies, Inc. was founded in 1983 to fill that void. Since then, we've established our own brand of new products, sensors, energy sources, battery enclosures, and custom-built seismic equipment. We have aided several seismic, engineering, and environmental contractors, oil corporations, geophysical firms, universities, and research organizations in the acquisition and sale of new and used geophysical and seismic equipment.
We are not only the largest "Exclusive Used Equipment Broker" in the geophysical sector, but we also have a New Products branch. We also appraise assets and holdings to meet our clients' accounting, financial, and legal demands.
