These direct negotiations open up all 33 offshore blocks over the Harper and Liberia basins. The process is open from 1st June 2021 until 30th November 2022. The Liberia Petroleum Regulatory Authority (LPRA, the Authority) is working in close collaboration with the National Oil Company of Liberia (NOCAL) to implement the next phase of exploration offshore Liberia.

This process follows a licensing round launched in 2020 and retains the attractive amendments to Liberia's Petroleum Law, following major regulatory changes in October 2019,

Applications will be processed on a first come, first served basis following the prescribed 5-phase process outlined on the LPRA website ( You can also contact TGS for relevant material and guidance using the form on this page and download the following Investment Information Package that we have prepared:

Thirty-three blocks are open for negotiation.  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.

TGS holds a range of multi-client data across the tendered acreage to support the blocks on offer both in the Harper Basin and the Liberia Basin. In May 2022, TGS announced the reprocessing of over 5,100 km2 of key 3D seismic covering blocks 8 & 9 in the Liberia Basin. The survey will be processed using a Pre-Stack Depth Migration (PSDM) workflow to enable optimal imaging of the main targets in the Cretaceous reservoirs to reveal the latest insights into prospectivity. Final deliverables are expected in Q2 2023.
