TGS and Spectrum have joined forces and expanded the Santos 3-D program to 15,000 sq km (5,791 sq miles) over the prospective southern Santos Basin offshore Brazil, the companies said on Oct. 16.

TGS and Spectrum will be equal partners with data processing and imaging to be performed by TGS. The survey covers an area south of the high-profile discoveries of the Santos Basin and the recent sought-after blocks offered in Rounds 2,3,4,5 and 15.

“Spectrum is excited to cooperate with TGS in this survey over such a highly prospective area. The two companies will be working together to unlock the southern Santos Basin for exploration. The Santos Basin is one of the hottest exploration basins in the world with a high potential for further discoveries in deep water,” Rune Eng, Spectrum’s CEO, said.
