Magseis chooses Sonardyne acoustics for seismic survey

Magseis rig Oil Review Middle EastSeabed seismic services firm, Magseis, has chosen acoustic positioning equipment from Sonardyne International Ltd, UK, to support its deep water ocean bottom seismic survey of the Red Sea

The S78 project, which is taking place in partnership with BGP on behalf of Saudi Aramco, is due to last nine months and will involve deploying a large network of ocean bottom recording nodes.

According to Magseis, it will be positioned using Sonardyne’s Ranger 2 USBL (Ultra-Short BaseLine) and Small Seismic Transponder (SST) technologies.

Magseis is also set to launch its proprietary Marine Autonomous Seismic System (MASS), which uses thousands of small nodes to design a grid pattern of receivers on the seabed.

The Norwegian-based firm is also expecting delivery of Sonardyne’s Lightweight Release Transponders (LRTs) and rope canisters to allow recovery of seafloor equipment following data acquisition. LRTs float back up to the surface, enabling the equipment to which they are attached to be towed up.

Trevor Barnes, sales manager at Sonardyne said, “Magseis have been long-term users of our technology and we’re naturally very pleased that they have chosen to increase their investment with this major order for acoustic positioning and release equipment.

“We are continuously evolving our subsea technology to match the ever increasing demand for higher positional accuracy and increased measurement speed so that seismic operators can generate more detailed reservoir information whilst minimising cost.”
