Offshore survey specialist Shearwater GeoServices has secured a conditional letter of award for a 2D seismic acquisition and fast-track processing project.

The award has been granted by Total E&P South Africa. Shearwater noted that the survey will be the company’s first project offshore South Africa conducted at block 11B/12B.

Situated in the Outeniqua Basin, 175km off the southern coast of South Africa, block 11B/12B covers an area of 19,000km². The water depths of the block range from 200m to 1,800m.

Shearwater’s survey, which is expected to take two months for a seismic survey at Total’s block, will initially cover 3,650 linear kilometres by the multi-purpose vessel (MPV) SW Cook. The offshore survey will start in the fourth quarter of 2019.

Shearwater GeoServices CEO Irene Waage Basili said: “The SW Cook worked for Total in the North Sea this summer and we are very pleased to see it continue to acquire seismic for Total in South Africa on a project where we will also leverage the flexibility of our Processing & Imaging teams.

“They will provide fast turnaround results to Total during the survey enabling rapid decision making.”

SW Cook, which is one of the three MPVs operated by Shearwater, has been working throughout the North Sea summer season on 3D and 4D seismic projects. It also serves as a source vessel on Total’s 2019 North Sea 4D programme.

In July, Total contracted Odfjell Drilling’s sixth-generation semisubmersible Deepsea Stavanger rig for the next phase of drilling on block 11B/12B.
