Marine geophysical services company Shearwater GeoServices has secured a contract from hydrocarbon exploration firm Apache to provide a 4D seismic survey with 3D extension over the Forties Field in the UK North Sea.

In a statement Shearwater said the contract work will start in the second quarter of this year and should last for about one-and-a-half months. The diesel/electric powered seismic vessel Amazon Warrior will carry out the survey.

The Forties oil field lies in UK Licence Block 21/10, approximately 140 miles north-east of Aberdeen. BP discovered it in October 1970.

Shearwater GeoServices CEO Irene Waage Basili said: “We are very pleased to see a Shearwater Qmarine 4D crew returning to the Forties Field for the fourth time.

“The project adds to the North Sea 4D program we announced earlier this year and we continue to demonstrate industry leading technology and experience in 4D seismic.”

The Qmarine point-receiver marine seismic system is one of Shearwater’s marine acquisition technologies, entering the market in 2000.

In January this year, Shearwater announced multiple 4D surveys execution in the 2020 North Sea season.

In September last year, Shearwater GeoServices secured new Isometrix seismic acquisition projects for Lundin and Spirit Energy Norway in the Barents Sea.

In August, Shearwater began a 3D seismic survey over the Pensacola Prospect on Licence P2252 in the Southern North Sea.
