Permanent Reservoir Monitoring
Surface Orbital Vibrators
Continuous seismic monitoring – SOVs are available 24/7 for permanent reservoir monitoring, offering unmatched economy for multi-source permanent installations. Life-of-field fixed source-receiver arrays are used to detect subtle changes in reservoir properties unobtainable through conventional seismic approaches. Distributed SOVs provide new opportunities for VSP and reflection monitoring of time-lapse processes.
Powerful swept frequency surface orbital vibrators (SOV) for active excitation of your receiver network. These sources are ideal for continuous monitoring using permanent sensor arrays for life-of-field applications. SOVs complement fiber-optic DAS arrays, taking advantage of their wide spatial aperture and provide the ability to stack high energy sweeps to overcome sensitivity limitations.
A range of models match user requirements with force from 1,365 kgf up to 23,000 kgf.
Programmable sweep can be used to tune source power spectra for optimal data collection.
Source function monitored locally using a 24-bit 3-channel seismic recorder.
