Global Marine Energy, a division of marine engineering company Global Marine Systems Ltd., announced today that it has completed two projects for Petroleum Geo-Services (PGS) to deploy and recover seabed receiver cables for its Multi- Transient Electro-Magnetic (MTEM) surveys.
The first project utilized Global Marine's specialized cable ship Wave Sentinel to lay the receiver cable on the seabed which accurately recorded subsurface resistivity at predefined locations. The recordings were then transmitted to the vessel for quality control before being sent ashore for further processing and detailed study by PGS.
The second project used Global Marine's experience in mobilizing specialist equipment and installation teams on to a vessel of opportunity for work in the Mediterranean.
The PGS proprietary MTEM technology was developed to detect the presence of hydrocarbons beneath the ocean floor, helping to pinpoint the location of oil and gas deposits. MTEM works by producing resistivity profiles over potential reservoirs, thereby helping oil companies determine the location of oil and gas reserves before drilling. By combining seismic and EM data, drilling success rate can be improved while reducing the environmental impact of drilling unsuccessful and expensive dry holes.
"These assignments have seen us pushing the boundaries of this technology in order to locate new sources of oil," said Leon Walker, President of PGS EM. "Our past success with Global Marine, combined with their experience in subsea engineering and expertise in cable installation made them the logical partner for these projects."
"Working with MTEM technology is precisely the type of project that Global Marine Energy was created for," said Ian Gaitch, Director of Global Marine Energy. "It offers an opportunity to leverage our expertise to help increase the efficiency of oil exploration while reducing its impact on the environment."
