Petrobras filed an oil show report for the well with the ANP on 31 March 2020 and issued a press release on 2 April 2020 indicating the well may be a discovery in porous pre-salt reservoirs. The company will analyze the well data to determine additional future exploration activity in the block.  The current 2nd side-track wellbore was spudded on 16 December 2019 after junking the original wellbore in mid-November 2019 and the first side-track wellbore in early December 2019.   The well has a proposed total depth (PTD) of 5,915 m and is targeting the Early Cretaceous Barra Velha and Itapema formations. The well reached a total depth (TD) of 5,933 m  The West Tellus D/S drilled the well in a water depth of 1,995 m.   The NFW is located in the south-central area of the block 50 m south of the location of the junked 1-SPS-107 (1-BRSA-1373-SPS) and 1-SPS-107A (1-BRSA-1373A-SPS), and approximately 35 km north-east of the 3-EQNR-003-SPS Equinor suspended with oil shows in the southerly adjoining N_CARCARA block in mid-2019.   Petrobras is operator of the contract with 30% working interest, ExxonMobil holds 28%, Equinor has 28%, and Petrogal holds 14%.   On 17 December 2018, the consortium of Petrobras, ExxonMobil, Equinor, and Petrogal, was granted an official award for the 1,285.33 sq km Uirapuru_P4 contract, BLC_Uirapr block from the 4th PSC Pre-Salt Bid Round after contract signature with the government. Petrobras is operator of the contract with 30% working interest, ExxonMobil holds 28%, Equinor has 28%, and Petrogal holds 14%. On 7 June 2018, the Petrobras led consortium was granted a preliminary award for the Uirapuru block from the 4th PSC Pre-Salt Bid Round. There were three other bids for the Santos Basin block by Petrobras led consortiums. The Uirapuru block was the most contested block in the bid round with four bids and a first for the PSC bid rounds with a consortium without Petrobras winning the bid offering more state take than the Petrobras led consortium. The consortium of ExxonMobil, Equinor, and Petrogal offered a state take of 75.49% while the Petrobras led consortium of Petrobras with 45%, Total with 20%, and BP with 35% bid 72.49% state take. As a result, Petrobras had to make a decision to join the winning consortium and take its minimum 30% working interest resulting in Petrobras as the operator with 30%, ExxonMobil with 28%, Statoil Brasil (Equinor) with 28%, and Petrogal with 14%. The consortium paid a fixed signing bonus of USD 736.11 million, at 1 USD to 3.60 BRL, and has estimated minimum investment guarantees of USD 68.33 million for the one well drilling commitment during the seven-year exploration phase.
