Sercel launches HT/HP downhole monitoring tool

27th October 2014

Sercel, a division of CGG, has launched the GeoWave II, a downhole seismic tool for conducting safe and efficient Vertical Seismic Profile (VSP) and hydraulic fracture monitoring surveys in hostile well environments

“We are proud to add a new cutting-edge product to our suite of downhole tools, demonstrating once again Sercel’s commitment to offer our customers new technologies in all our market segments,” said Pascal Rouiller, Sercel CEO.

“The new GeoWave II is our response to the explorations and production industry’s growing need to deploy larger arrays in more hostile conditions for applications ranging from microseismic monitoring in deeper shale plays to 3D VSP surveys in challenging environments."

GeoWave II is the industry’s first digital multi-level array specifically designed for high-temperature, high-pressure wells.

It is capable of continuous data acquisition at temperatures of up to 400°F/205°C and is pressure-rated to 25,000 psi/1,725 bar. With new optimized high-speed telemetry, up to 120 levels can be safely deployed on standard wireline for hotter and deeper reservoirs.

GeoWave II can also be configured to provide the longest array (3000 metres) in the market by using larger intertool spacing.

Optimised for seismic surveys and microseismic applications, GeoWave II allows downhole operations to be conducted in any well type with a diameter of 3’’ to 22’’, and is compatible with downhole tractor systems for deployment in highly deviated and horizontal wells. It is manufactured to the highest standards with material and components designed to withstand high-pressure/high-temperature environments for prolonged periods without the need for a cooling system.

It features system testing and monitoring capabilities and also allows easy deployment and safe retrieval in all conditions.
