Norwegian geophysical companies TGS and Magseis Fairfield have secured new work for ocean bottom node (OBN) seismic surveys in the North Sea and Gulf of Mexico.
TGS said it has been awarded an extension to the 2021 Noaka OBN survey in the Norwegian North Sea.
The Noaka22 survey will comprise an additional 318 square kilometres of multi-
client OBN data located within the APA area between Oseberg and Alvheim offshore Norway.
TGS said the Noaka fields are one of the largest developments on the Norwegian Continental Shelf, with recoverable reserves of more than 500 million barrels of oil equivalent.
The area has witnessed significant infrastructure-led exploration activity in recent years, and further prospectivity is anticipated.
The acquisition for Noaka22 is expected to begin this month, with final processing in the fourth quarter of next year.
Kristian Johansen, TGS’ chief executive, said: “TGS continues to lead the way in delivering multi-client OBN data to support E&P companies as they seek to find new hydrocarbon reserves and maximise the longevity of their production activities. We remain committed to providing the industry with the best data for quality subsurface imaging as evidenced by the growing number of OBN surveys in the TGS multi-client library.”
Meanwhile, Magseis Fairfield said it has been awarded two OBN contracts — one in the North Sea and one in the deep-water Gulf of Mexico.
The first is a contract in the same area of the Norwegian North Sea where Magseis last year used its Z700 crew.
The new contract extends the duration of operation by one month, to a total of three months.
“We are pleased to have been awarded this project, as a result of good dialogue with our customers in exploring synergies with other planned activities,” Magseis Fairfield chief executive Carel Hooijkaas said.
The OBN project in the Gulf of Mexico is from a repeat customer, with an option for a second programme extension. The initial survey is scheduled to be done with Magseis Fairfield’s ZXPLR technology and is expected to take three months.
