On 11 May 2020, Petrobras issued a press release indicating that the 9-AB-135D-RJS well, in the Albacora production concession in the Campos Basin, encountered 214 m of reservoirs, with light oil, as indicated by test made at 4,630 m. The reservoir rocks are most likely Pre-salt microbialites of the Aptian Macabu Formation.  The 9-AB-135D-RJS service well spudded on 15 February 2020. The well is assumed to continue to be drilled by the Ocyan NORBE VIII drillship at a water depth of 450 m.  The Albacora Block is owned and operated 100% by Petrobras since August 1998 when it was officially awarded during the ANP Round 0. The ANP approved a modified development plan for the contract in November 2014 requiring the company to develop the pre-salt Macabu Formation reservoir.  The Albacora Field was discovered in 1984 by the 1-RJS-297-RJ new field wildcat (NFW) spudded in August 1984 and completed in September 1984 as an oil discovery. The NFW found oil in the post-salt Albian sandstones of the Namorado Formation. In November 1984, well 1-RJS-305-RJ discovered 2,800 bo/d in Post-salt sandstones of the Carapebus Formation, and 640 bo/d in the Namorado reservoir. The well spudded in September 1984 and it was completed in November of the same year.   In April 2011, Petrobras announced the discovery of Pre-salt carbonates of the Macabu Formation by well 6-BRSA-899D-RJS, Forno prospect, located in the south-central area of the Albacora Block. The well spudded in April 2010 and it was completed in October 2011. The discovery was originally reported to have 104 m of pre-salt Macabu Formation pay.Â  However, in its June 2015 environmental permit the company indicated that the well had 255 m of gross pay from 4,458 m to 4,713 m with 31Â° API oil and 40 PPM H2S.   Petrobras has drilled three other outpost wells to the Forno discovery.Â  The first was the 3 km northeast outpost 3-AB-125-RJS (3-BRSA-1123-RJS) suspended as an oil producer on 30 July 2013. The second 9.4 km southwest outpost was the 3-AB-126-RJS (3-BRSA-1238-RJS) suspended as an oil producer in early November 2014.Â  The third 5.7 km north northwest outpost was the 3-AB-128-RJS (3-BRSA-1316-RJS) suspended as a potential oil producer on 17 June 2016 with an early-October 2016 press reports indicating it had 45 m net pay section below 4,600 m.   The Albacora Field currently produces only from the Post-salt reservoirs. As of December 2019, the field has produced 909.17 MMbo and 590.29 Bcfg. The 2019 ANP BAR reserves report estimates original oil in place (OOIP) of 4.35 Bbo and original gas in place (OGIP) of 3.39 Tcfg. Assuming a 35% recovery factor (FR), the recoverable oil is estimated at 1.52 Bbo and assuming a 43% RF for the gas, a 1.46 Tcfg is estimated for the recoverable gas.
9-BUZ-39DA-RJS (Petrobras 90% op., CNOOC 5%, CNODC 5%), Service well in SE BÃºzios field area, southeastern part of the Buzios block, Santos pre-salt, WD 2104m, oil encountered (208m column below 5400m), ops continue.
