Local sources mentioned that during the last week of August 2019, Lukoil opened a data room for its Lower Congo Basin Nanga IIA and Nanga IIB blocks. Â In July 2019, sources indicated that Lukoil had replaced GazProm as operator of the permit.  The reservoirs expected in the area are the Vendji, Mengo, Djeno and Chela formations and the source rock in the area is the Sialivakou shales (known as the Bucomazi in DRC and Angola).   At least five prospects are known to have been identified within the Nanga IIA block (Benba Nord East, Kitombo Nord, NGwadi Nord-East, Nkusu, NTombo). Prospective resources are thought to be around 750 MMboe (90% oil). Most of the prospective resource numbers came from Eni (2010). Itâs worth noting that SOCO was awarded a one-year exploration licence for the Nanga II A block in October 2013. The deal included the evaluation of aeromagnetic data and reprocessing several existing 2D seismic lines before deciding on a 3D seismic survey. Following the completion of the interpretation of the reprocessed seismic data, the company relinquished the exploitation licence, which expired in October 2014.  Lukoil operates the permit with an 85% interest, Societe Nationale des Petroles du Congo (SNPC) holds the remaining 15% stake.  Background information   In late 2017, it is understood that Gazprom was awarded the Nanga II exploration licence in partnership with SNPC.
