On 11 May 2020 Petrobras announced the discovery of âgreat qualityâ oil with the 9BUZ39DARJS well in the Buzios Field of the pre-salt Santos Basin. The well continues drilling but an oil column of at least 208m has been confirmed through tests at depths below 5,400m, according to the Petrobras statement. It is classified as special well located in the southeastern part of the field. The directional well was spud on 10 February and is being drilled by the ODN I drillship in a water depth of 2,104m. It has a planned total depth of 6,069m with a pre-salt objective. This is the second attempt to drill this wellbore. The first well (9BUZ39DRGS) was junked and abandoned after nine days of drilling and reaching a depth of 1,016m below the seafloor at a location less than 100m from the 9BUZ39DARJS. Two other special classification wells are also currently drilling in Buzios Field. The 9BUZ40DRJS was spud by the Etesco Takatsugu J drillship on 14 March in 2,033m water depth with a planned total depth of 6,010m and the 9BUZ41DRJS was spud by the Ocean Courage drillship on 7 March in 1,991m water depth with a planned total depth of 6,178m. The Petrobras press release noted that Buzios Field is covered by the largest 3D seismic data volume based on ocean bottom nodes (OBN) in the world, with technology among the most modern to construct high resolution images of oil reservoirs in the field and allow optimization of productivity and profitability at Buzios. Petrobras is the operator with 90% of the Buzios Field while partners CNOOC and CNODC both from China each have 5%. On 30 March 2020, the ANP announced the final signing the production sharing contracts of the Buzios and Itapu blocks from its highly anticipated Onerous Assignment Surplus Production Rights Bid, also called the Transfer Rights area, in the Santos Basin pre-salt polygon. The round was held on 6 November 2019. The contract has a 35-year term with a signing bonus cost of R$ 68,194,000,000 (US$ 17 billion) and a pledge of profit oil of 23.24 %. This was the minimum bid and Petrobras was the sole bidder. The signing bonus was paid in December 2019. Buzios is touted as Brazilâs largest field. Petrobras already has four FPSOs operating in Buzios and plans to install more by 2023.
