TGS in seismic survey offshore Ireland

Norwegian seismic data acquisition company TGS is undertaking a new multi-client acquisition project, Crean 3D on the Irish Atlantic Margin.

Crean 3D (CRN 3D) is a multi-client survey of more than 5,400 square kilometers located in the South Porcupine Basin between the Porcupine High and the Irish Mainland Platform.

Multi-level targets exist, such as Paleocene and Mesozoic channel/fan systems overlying tilted fault blocks, TGS has explained.

Exploration success on the Newfoundland Labrador conjugate margin coupled with historical exploration in Atlantic Ireland has resulted in significant acreage being licensed, TGS said.

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 June 2017. Data processing will be performed by TGS using its Clari-Fi(TM) broadband technology.

“Crean 3D will expand TGS’ modern 3D coverage in the underexplored Porcupine Basin. With the successful Atlantic Ireland license round in 2016, we see that activity across the Porcupine Basin is continuing to increase, creating exciting new opportunities. The Crean 3D survey further adds to our Atlantic margins library which also includes data and new acquisition in the Norwegian Sea, North West Africa and Newfoundland Labrador,” said Kristian Johansen, CEO for TGS.

The work will be carried out by Shearwater’s vessel. This was confirmed by Shearwater in a separate statement on Monday.

Shearwater, a GC Rieber Shipping ASA’s 50% owned geoservices company, said it had received an award from TGS for the Crean 3D project, strengthening Shearwater’s backlog in the EAME Region for the 2017 season approximately 4 additional vessel months.

The survey will be acquired utilising one of Shearwater’s high end 3D vessels, Shearwater said.
