In December 2018, the ANP published information regarding the working interest transfer and contract split in the Petrobras operated BM-SEAL-004 and BM-SEAL-004A contracts retroactive to 15 August 2018.Â  The BM-SEAL-004 contract covers an area of 813.22 sq km and retains the original working interest split of Petrobras as operator with 75% working interest and ONGC with 25% working interest.Â  The BM-SEAL-004A contract covers an area of 319.43 sq km and is Petrobras 100%.  On 23 May 2018, Petrobras published its deal teaser information offering non-operated working interest in the BM-SEAL-004, BM-SEAL-004A, BM-SEAL-010, and BM-SEAL-011 contracts and nine blocks in the offshore deep-water Sergipe-Alagoas Basin.  On 31 August 2016, the ANP granted formal approval for partner ONGC to transfer its 25% working interest in the BM-SEAL-004A contract to operator Petrobras.Â  Petrobras now has 100% working interest in the contract.Â  The BM-SEAL-004 contract was separated with Petrobras having 75% working interest and ONGC 25% working interest.Â  The BM-SEAL-004A contract in which Petrobras has 100% working interest includes the Poco Verde discovery evaluation plan (PAD).  On 18 February 2016 the ANP approved a modification to the Petrobras operated discovery evaluation plan (PAD) PA_1BRSA1022SES_BM-SEAL-4, Poco Verde prospect. The ANP granted the operator an extension of the final expiry date for six PADs including the PA_1BRSA1022SES_BM-SEAL-4 from 30 December 2018 to 1 December 2020. This is the 2nd extension for the final PAD expiry date.  The 2,265 sq km, BM-SEAL-004 contract was originally awarded to Petrobras and Amerada Hess through the ANP Round 2 on 15 September 2000.Â  Hess withdrew from the contract in 2003 and Petrobras assumed its 40% working interest. ONGC acquired a 25% interest from Petrobras in the contract in the third quarter of 2008, when the ANP approved the transaction. Petrobras continues as the operator with a 75% interest.Â  Through various part relinquishments and extensions the block now covers 1,132.71 sq km and the final expiry period occurred on 30 April 2014.Â  The entire remaining area was converted into the discovery evaluation plan (PAD), PA_1BRSA1022SES_BM-SEAL-4 on 13 November 2013 based on the results of the 1-SES-159 (1-BRSA-1022-SES), Poco Verde prospect. Â   Besides the 1-SES-159 (1-BRSA-1022-SES), Poco Verde prospect oil and gas discovery Petrobras also drilled the 3-SES-181 (3-BRSA-1251-SES) outpost as a successful gas and condensate discovery in October 2014.Â  In September 2015 the operator suspended operations on the 3-SES-189 (3-BRSA-1303-SES) outpost as a separate pool oil discovery.     Petrobras is operator of the 1,132.71 sq km, BM-SEAL-004A contract with 100% working interest.
