Petrobras and Eneva discovered gas fluids in wells 1-BRSA-1380D-RJS and 1-ENV-19-MA, respectively, according to data published by the ANP last Friday. The notification of evidence of hydrocarbons was made to the ANP on August 12, in the case of the state-owned company, and on August 9, in the case of Eneva.

Located in the C-M-346 block, in deep waters in the Campos Basin, the Petrobras well began to be drilled in May this year, in a water depth of 2.849 m and by Seadrill’s West Tellus rig. The block is part of the SC-AP3 sector, which contains another five blocks operated by the state-owned company (C-M-210, C-M-277, C-M-344, C-M-411 and C-M-413).

In all, Petrobras plans to drill seven exploratory wells in these areas, three of which are firm (named Mairarê, Urissanê and Mairarê Oeste) and four contingents (Urissanê Oeste, Quiriri, Mairarê Pocema and Tutoia). Another discovery was made in this cluster at the end of January this year, by the Urissanê well, in block C-M-411.

The end of the first exploratory period for CM-346 is scheduled for January 2025. The area was purchased in the 14th Bidding Round of the ANP, in 2017, the same round in which Eneva purchased PN-T-134, where the well 1-ENV-19-MA.

Eneva’s well began to be drilled in mid-June this year. The onshore block is located in the Parnaíba Basin, and has its first exploratory period scheduled to end in October 2024, already having the deadline extension requested by the company and accepted by the ANP.

PN-T-134 was sold together with four other blocks in the same round: PN-T-117, PN-T-118, PN-T-119 and PN-T-133, which have not yet drilled wells. At the time of the auction, Eneva stated that it intended to replicate the gas-to-wire model in the five auctioned blocks.
