TGS has commenced acquisition of a 3D multi-client survey covering 1,239 sq miles (3,210 sq km) in the Erlend Basin on the U.K. continental shelf (UKCS), West of Shetlands.

This is the first multi-client 3D survey in the Erlend Basin and builds on the improved imaging shown by reprocessed 2D data.

The new 3D data expands on TGS' northern North Sea 3D survey making a total contiguous volume exceeding 3,861 sq miles (10,000 sq km).

TGS has chartered the Polarcus Samur for the first phase of the acquisition. The remaining acquisition will be completed during the 2012 season by the Polar Duchess, already on charter to TGS. 

Processed data will be available for delivery and licensing second quarter 2013.
