Shearwater GeoServices has been awarded a large Ocean Bottom Node 4D Baseline survey over the Jubarte Field in the Campos Basin offshore Brazil.
Shearwater said it had positioned itself as a leading player in the deepwater OBN market, building on its established leading positions in the hybrid and shallow water ocean bottom seismic markets.
Shearwater CEO Irene Waage Basili said: “We welcome this contract awarded by Petrobras and look forward to supporting their continued ambitions in the Jubarte Field.
“This deepwater OBN award reflects our experience in operating offshore Brazil, our position in the deep water OBN segment, and our strategy of marine seismic leadership and unique in-house developed technology and solutions.”
The 810km2 survey will commence in the first half of 2021 and be conducted over a three-month period.
Shearwater said the survey would utilise the SW Diamond operating Shearwater’s unique 3×3 source which is equipped with three sub-arrays on each of the three sources, compared to the conventional two, allowing increased efficiency without source compromise.
While conventional sources vary their energy in one direction versus another, this project’s omni directional source is designed to give out energy uniformly in all directions which will be key to 4D repeatability for this rich azimuth deepwater OBN acquisition, Shearwater added.
