According to TGS, these are highly prospective deep water pre-salt blocks awarded by Sonangol to E&P firms in December 2011.
TGS senior VP for Africa, Middle East and Asia Pacific Rod Starr said the company looks forward to its new, long-term relationship with Sonangol to support oil and gas exploration in Angola.
"TGS’ commitment to expanding multi-client data in the offshore areas of West Africa has extended over ten years and we are excited to have the opportunity to now add 3D data in offshore Angola to the TGS data library," Starr said.
