Shell Brasil expands participation in Mero and Atapu pre-salt fields

Shell Brasil is significantly deepening its commitment to Brazil's ultra-deepwater pre-salt basin, acquiring additional stakes in the Atapu and Mero fields for $2.9 billion. This strategic move sees Shell Brasil increase its participation in the Atapu field by 21.25% and in the Mero field by 3.75%. The transaction, announced on 2026-03-12, reinforces Shell Brasil's focus on high-value, deepwater oil and gas exploration and production, aligning with Shell's global strategy for its energy portfolio. By expanding its footprint in these prolific Brazilian assets, Shell Brasil aims to consolidate its position within a critical global hydrocarbon province. This acquisition represents a direct investment into proven pre-salt reserves, offering long-term production upside for the buyer. Petrobras, the Brazilian state-owned oil and gas major, is divesting these stakes, monetizing assets from its extensive exploration, production, refining, and distribution portfolio. This $2.9 billion transaction allows Petrobras to optimize its capital allocation while maintaining a significant presence across Brazil's energy landscape. Shell Brasil, already a major energy company in Brazil with a primary focus on deepwater pre-salt, further solidifies its operational presence through this acquisition. Pré-Sal Petróleo S.A. (PPSA), a Brazilian state-owned company, continues to manage the Union's interests in these pre-salt fields under the production sharing regime from its Rio headquarters, overseeing the broader framework of these ultra-deepwater assets. This transaction contributes to the ongoing re-calibration of portfolios among major players in Brazil's pre-salt sector, as Shell Brasil actively pursues growth in its core E&P areas.
