Got gas? OYO Geospace helps companies find gas and oil. It makes instruments and equipment used primarily by seismic contractors and oil and gas companies to gather and process seismic data to zero in on hydrocarbons. The company's geophones detect energy from the earth's subsurface, and its hydrophones detect changes in pressure and gather seismic data in water. Other products include seismic leader wire, geophone string connectors, seismic telemetry cable, and thermal imaging equipment; all are compatible with most seismic data-acquisition systems. OYO Geospace also makes its thermal printers available for the commercial graphics industry.
