The company said the first data has been sent to pre-funding customers and is now available to all industry clients. TGS worked with Russian partner DMNG to cover the ‘highly prospective’ area.

TGS CEO Kristian Johansen said: “Offshore Russia has long been an important region for TGS and the completion of the second phase of processing in the Sea of Okhotsk further strengthens our library of data here.

“There have been a number of significant discoveries of both oil and gas in recent years and our seismic data will be a core tool for explorers as they seek to further develop offshore hydrocarbon resources in the area in the years to come.”

It follows TGS’ 2D Phase 1 Clari-Fi broadband reprocessing of 18,970km2 of data last year. Together, the two packages will provide higher quality data for explorers and interpreters, assisting decision-making.
