On 30 August 2018, the ANP approved of Imetame acquiring 100% working interest in the BT-POT-16 contract, Joao de Barro production concession, from former operator Norteoleum with 50% and partner Aurizonia with 50%.  In early-September 2016, the ANP reported that UTC Exploracao e Producao SA officially transferred all equity in six exploration blocks and eight production concessions to Norteoleum Exploracao e Producao SA on 1 August 2016.Â  All of the assets are in the onshore Potiguar Basin.Â  Norteoleum is a subsidiary formed in 2009 of UTC Participacoes parent company that handles the exploration and production duties for the group.Â  It is speculated the transfer of assets has to do with the reported possible sale of the oil and gas business by the group.  On 30 August 2011, the ANP approved the change of interest holder in the BT-POT-16 contract Joao de Barro production concession, carved out of the BT-POT-16 contract in the Potiguar Basin. UTC Engenharia S.A. transferred its 50% working interest to UTC Oleo e Gas S.A.    In May 2010, UTC Engenharia farmed into Aurizoniaâs Joao de Barro production concession for a 50% working interest and operations. In the first two months of 2010, the concession produced on average 28 bo/d and 81 Mcfg/d.   On 2 March 2006, Aurizonia was granted a Final Award from the ANP for the 3.49 sq km Joao de Barro production concession for a carve-out concession of the ANP Round 5 BT-POT-016 contract POT-T-302 block in the onshore Potiguar Basin. Â Aurizonia discovered Joao de Barro with the 1-AURI-2-RN (1-AURI-2-RN) and the 3-AURI-9-RN (3-AURI-9-RN) wells. Â Aurizonia was to conduct a long term production test of the two wells, expecting 800 bo/d from these wells, and will then tie in additional producers. Â Â Aurizonia has drilled a total of six wells within the production concession area.
