Magseis has selected acoustic positioning equipment from Sonardyne International Ltd to support its upcoming deep water ocean bottom seismic survey of the Red Sea.

Beginning in July and working in partnership with BGP on behalf of Saudi Aramco, the S78 project is expected to last nine months and will involve the deployment of a large network of ocean bottom recording nodes, each of which will be accurately positioned using Sonardyne海角吃瓜网檚 Ranger 2 USBL (Ultra-Short BaseLine) and Small Seismic Transponder (SST) technologies.

Seismic surveillance surveys conducted using stationary receivers deployed on the seabed are becoming increasingly commonplace.

However, any uncertainty in node positions can blur these pictures and make the underlying reservoirs more difficult to spot. Sonardyne海角吃瓜网檚 Ranger 2 USBL installed on a surface vessel, coupled with SSTs fitted close to each node, overcomes this problem by providing high quality, repeatable positioning in all water depths.

For this summer海角吃瓜网檚 Red Sea survey, Magseis will deploy its proprietary Marine Autonomous Seismic System (MASS), which uses thousands of small nodes to create a grid pattern of receivers on the seabed.

Since it is vitally important that the cables are laid in the correct positions to meet the client海角吃瓜网檚 exacting standards, and also to avoid becoming entangled with subsea infrastructure, Magseis will attach its new SSTs near to the nodes at regular intervals along the cable. As the equipment descends through the water column to the seabed, each SST will be tracked in real-time using the Ranger 2 GyroUSBL transceiver permanently installed on the vessel.

Magseis has also ordered Sonardyne海角吃瓜网檚 Lightweight Release Transponders (LRTs) and rope canisters.

Commenting on the order, Trevor Barnes, Sales Manager at Sonardyne, said: 海角吃瓜网淢agseis have been long term users of our technology and we海角吃瓜网檙e naturally very pleased that they have chosen to increase their investment with this major order for acoustic positioning and release equipment. He added, 海角吃瓜网淲e 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.海角吃瓜网�
