The Liberia Petroleum Regulatory Authority originally announced the launch of its next offshore licensing round in April 2020. The round was launched in parallel with attractive amendments to Liberia's Petroleum Law, following major regulatory changes in October 2019, and the extension of the exploration period, in order to attract international investors. In addition, Liberia subsequently announced changes to the bidding criteria to further enhance the attractiveness of the licence round terms. Liberia Video Link GIF 2

Nine blocks were offered in the Harper Basin, one of the last unexplored and undrilled regions offshore West Africa: LB-25, LB-26, LB-27, LB-28, LB-29, LB-30, LB-31, LB-32, LB-33. The new block demarcation followed an update to the petroleum bill in 2019, with a maximum block size of 3,500 square kilometers, and alignment with the ECOWAS grid.
