On 11 May 2020, Petrobras issued a press release indicating that the 9-BUZ-039DA-RJS well in the Buzios production concession in the Santos Basin, encountered 208 m of reservoir rocks, assumed to be the pre-salt Barra Velha Formation, with the same quality oil as the one that is being produced in the Buzios field, as indicated by test. The company did not release any more details regarding those tests.  The 9-BUZ-039DA-RJS service well spudded on 10 February 2020 and it is still being drilled by the Ocyan drillship ODN I on 2,104 m of water. The well lies in the southeastern part of the Buzios block, outside the main structure of the field in what it could be a new pool or extension of the current structure.  The Buzios Field, in the block of the same name, is under two different contracts: the Cessao Onerosa or Transfer of Rights (ToR) contract and the ToR Excess Volumes. On 30 March 2020, the consortium of Petrobras, CNODC, and CNOOC were granted a final award for the 852.21 sq km Buzios block in the deep-water offshore Santos Basin from the 2019 ToR Excess Volumes PSC Bid Round. Petrobras is operator with 90% working interest, CNODC holds 5% working interest, and CNOOC holds 5% working interest.   For the ToR contract, Petrobras holds 100% working interest. This special concession contract regime, created in 2010, allowed Petrobras to explore and produce hydrocarbons, up to 5 Bboe, in six contract areas of the pre-salt, 3.06 Bboe for Buzios.  The Buzios Field is currently the largest commercial field in Brazil. The field was discovered in 2010 by stratigraphic well 2-ANP-001-RJS drilled in the Franco prospect. The well was targeting Lower Cretaceous Pre-salt microbialites and coquinas of the Barra Velha and Itapema formations. Appraisal of the Buzios Field started in May of 2011 and concluded in December of 2013 with the declaration of commerciality. The Franco prospect was re-named Buzios Field. Development drilling started in September of 2014 and is still on-going. Secondary recovery drilling started in January of 2015 and is also still on-going. Gas injection in Buzios started in August of 2018. Buzios contains oil of about 28Â° API, GOR of 1,432 cu-ft/bbl, CO2 of 23% molar, and H2S between 30-90 ppmv. The 2019 ANP BAR reserves report estimates original oil in place (OOIP) for Buzios Field of 29.15 Bbo and original gas in place (OGIP) of 29.08 Tcfg. Assuming a 24% recovery factor (FR) the recoverable oil is estimated at 7 Bbo and assuming a 41% RF for the gas, a 12 Bcfg is estimated for the recoverable gas.  In March 2020, Petrobras announced that the Buzios field reached a production record of 640 Mbo/d and 790 Mboe/d. The field is producing from four platforms: P-74, P-75, P-76 and P-77. In January 2020, the P-77 platform reached its production capacity of 150 Mbo/d.
