The ECC is required by the Proponent (Eco (Atlantic) Oil and Gas Ltd) with respect to the proposed 2D / 3D Seismic Survey Over the Area of Interest (AOI) covering Petroleum Exploration Licenses (PELs) Nos. 97 (Block 2012A), 98 (Block 2213B), 99 (Blocks 2111B and 2211A), and 100 (Blocks 2211Ba, 2311Aa and 2311Ab), Walvis Basin, Offshore Central Namibia. Although the targeted PELs Nos. 99 and 100 represents very large areas coverages, the actual likely location specific 2D/3D seismic survey projects will be limited to the specific areas with potential exploration leads / prospects. The PELs Nos. 99 and 100 falls in water depths ranging from ca-1500 m to more than ca-3000m, from east to west, respectively. The proposed 2D/3D seismic survey activities are planned to be implemented from January 2025. The proposed survey will be undertaken over multiple survey events and seasons using one (1) or two (2) third-party chartered survey vessels compliant to the International Convention for the Prevention of Pollution from Ships (MARPOL) and Namibian Maritimes legal requirements. Seismic survey method is the application of controlled generation of sound / acoustic waves by a seismic source to obtain an image of the subsurface. The generated acoustic wave that travels deep into the earth, is reflected by the various rock formations of the earth and returns to the surface where it is recorded and measured by receiving devices called hydrophones. In offshore environment, the energy source releases compressed air to generate seismic signals at regular intervals as the towing ship is moving. Signals reflected from geological interfaces below the seafloor are recorded by multiple hydrophones and transmitted to the seismic vessel for electronic processing. By analysing the time, it takes for the seismic waves to travel between the rock formations and the surface, geophysicists, geologists, and petroleum engineers use sophisticated software to create subsurface maps showing potential subsurface geological structures called reservoirs.
