Seismic Vibrator Control System

Seismic Vibrator Control System

Conoco, 1981-1985

Designed, built, programmed and tested digital feedback control system for hydraulic vibrator systems used for on-shore and offshore oil exploration at Conoco. This was the first time a completely digital feedback control system had been applied to these 3000psi hydraulic systems. U.S. Patent 4,857,919 was awarded for a novel digital method of acquiring servo-valve position information used in the feedback loop.
