As of early June, Pluspetrol is understood to have plugged and abandoned the Feijao 1x exploratory well within the north western part of the onshore Lower Congo Basin Cabinda Sul Block as dry. The well was drilled to a total depth of 2,961 m terminating in the Mayombe Complex â no hydrocarbons were encountered in the targeted Lucula Formation.   On 24 March 2020, Pluspetrol spudded the well, originally it had a planned total depth of 3,058 m targeting the Pre-Salt sandstones of the Lucula Formation (combined structural-stratigraphic trap). Secondary targets were the carbonates and sandstones of the Toca and Chela formations respectively.  The block includes the Castanha development area carved from the original Cabinda Sul block. It plays host to the Castanha field, discovered by Pluspetrol in 2010 and put into production in September 2013. The development area also includes the Coco, Noz, Lele and 123-5 fields. As of December 2019, the Castana field was producing in the region of 440 bo/d (in June 2018 the field was producing at 800 bo/d).   It's worth noting that in February 2019 Pluspetrol and the partners in the group received an extension to the exploration period for the Cabinda Sul block (Validity extended to 31 October 2022).   The interests in the permit are shared between Pluspetrol (operator) with 55%, partners are Force Petroleum (20%) and Sonangol P&P (25%).
