"PEL 83" is a Joint Venture between the block partners, namely Windhoek PEL 28 B.V. (a wholly-owned subsidiary of Galp Energia E&P B.V (i.e. Galp)), the National Petroleum Corporation of Namibia (NAMCOR) and Custos Investments. Galp holds an 80% controlling interest in Petroleum Exploration License (PEL) 83, while NAMCOR and Custos each hold 10%. Galp is currently the operator of PEL 83. Windhoek PEL28 B.V. (i.e. Galp) has successfully completed various exploration activities in PEL 83, including, amongst others, the following: A 3D-seismic survey between January and March 2019, over an area covering ~3,015 km2 of the PEL 83. Drilling of two exploration wells. Flow testing (DST) on one well. Windhoek PEL 28 B.V. received an ECC on the 10th of October 2023 for their offshore exploration well drilling, including well flow testing in PEL 83, on the basis of an approved Amendment Application. The Environmental Management Plan (EMP) was updated and approved as part of this process. This ECC is valid until 7 March 2026. Furthermore, Galp received an ECC from MEFT in November 2017 for their initial 3D towed streamer seismic survey activities in PEL 83, based on an approved EIA process and associated EIA Report and EMP. This ECC expired in November 2020. The well drilling and testing were recently conducted and the final well testing is expected to be completed in May 2024. Due to the positive results from the recent exploration activities, PEL28 B.V. plans to continue their exploration / appraisal activities in PEL 83 and requires new environmental clearances from MEFT for the following activities (similar to what was previously undertaken): 3-Dimensional (3D) towed streamers seismic surveys (i.e. changes in area / location from previously assessed / approved campaign) as well as ocean bottom node (OBN) seismic acquisition. (Relevant to this Application). Drilling campaigns (i.e. similar activities, but changes only in number of wells to be drilled) (A separate (Amendment) Application for this activity will be submitted). During the 3D towed streamer seismic surveys, high-level, low frequency sounds will be directed towards the seabed from near-surface sound sources (i.e. source air-gun arrays) towed by a seismic vessel. Signals reflected from geological interfaces below the seafloor will be recorded by multiple receivers towed in a multiple streamer configuration. An OBN seismic acquisition is very similar to a 3D towed streamer seismic acquisition regarding the source wavefields created by the air-gun arrays. The most relevant difference is the receiver’s component, which is placed on the seafloor for a specific period. This Application therefore relates specifically to further seismic (i.e. 3-Dimensional (3D) towed streamer and ocean bottom node (OBN)) surveys.
