UK-based independent Trident Energy plans to charter a semi-submersible drilling rig as part of a four-well campaign designed to revitalise operations at a cluster of shallow-water fields in the Campos basin offshore Brazil.

The company, which is backed by US private equity player Warburg Pincus, a couple of years ago acquired operatorship of the Pampo-Enchova complex from Brazilian state-controlled oil company Petrobras in a deal worth approximately $1 billion.

According to environmental documents submitted to Brazilian federal regulator Ibama and seen by Upstream, Trident is looking first to spud one well — known as Pampo Dry WH — on the Pampo field in the fourth quarter of 2024 with the modular rig SM-12.
