Towed Streamer EM

Adding resistivity information to seismic can highlight prospective areas that may have been overlooked. The insight gained from the combination of seismic and 2D or high-density 3D EM data datasets has significant value and a range of applications.

  • Cost-effective regional and near-field exploration
  • Reservoir level analysis of drilling hazards
  • Hydrocarbon saturation and production optimization

Structural interpretation is supplied from the seismic data and resistivity values from the Towed Streamer EM system. Both technologies seek to mitigate risk, in the search for and extraction of oil and gas. 

EM and Ocean Floor Geophysics

The state-of-the-art towed-streamer CSEM technology developed by PGS permits the acquisition of high-quality marine CSEM data in a fast and efficient manner. The system is currently available from Ocean Floor Geophysics, Inc (OFG). PGS transferred the exclusive rights to use the hardware, software and intellectual property associated with the PGS towed streamer CSEM system in September 2020. 

Dr. Lucy MacGregor, Principal Scientist at OFG Multiphysics says: “The PGS towed streamer CSEM system is capable of rapid acquisition of high-quality marine CSEM and is a perfect complement to existing seismic data when added confidence is needed to qualify acquisition, drilling, or relinquishment decisions. In addition to CSEM survey modeling and feasibility studies, OFG Multiphysics offers processing, interpretation, and multiphysics seismic integration.”
