TGS to start new 3D GoM survey

Written by  OE Staff Thursday, 21 December 2017 03:42

Geoscience firm TGS is to start a new multiclient acquisition project called Alonso 3D in the US Gulf of Mexico.

Alonso 3D will cover 6172sq km in the Atwater Valley and Lloyd Ridge protraction areas of the US Gulf of Mexico. TGS says multi-level targets exist, from Miocene to Jurassic. 

The project allows TGS to extend coverage from a core area in Mississippi Canyon into a more frontier area that TGS says is experiencing renewed interest from exploration and production companies.

TGS will acquire new 3D data to provide the higher spatial resolution required to delineate multiple plays at multiple levels. Acquisition is expected to start in February 2018. Data processing will be performed by TGS using its Clari-FiTM broadband technology.

"Alonso 3D will expand TGS' modern 3D coverage in the deepwater Gulf of Mexico. After a period of lower activity levels in the US GOM, this survey helps strengthen our position in an underexplored area that is of interest to our clients, ahead of upcoming lease turnover. The Alonso 3D survey further adds to our GOM library which also includes successful WAZ data programs to the north of this area," says Kristian Johansen, TGS' CEO. 

Polarcus announced today that TGS will conduct the survey using Polarcus'  XArray multiple source acquisition method.
