Creating a digital atlas for Namibia and western South Africa ///

This joint article examines how ARKeX, a provider of non-seismic geophysical services and data, together with Spectrum, a multi-client services and seismic imaging company, has created an exploration framework for Namibia and western South Africa, through the use of integrated interpretation of 2D seismic and potential field data. This article demonstrates how gravity and magnetic data, constrained by high-quality 2D seismic, can provide a fast, effective method for the structural modeling of frontier basins, in particular the crustal architecture of the Namibian passive margin, and the distribution of petroleum basins. To achieve this objective, ARKeX and Spectrum mapped structural elements, updated basin definitions and resolved the extent of different crustal types at the passive margin studied.
