Conventional core viewing display of the Upper Cretaceous, Lower Grudja Reservoirs, Onshore Mozambique

Abstract

SummaryThis core view presentation focuses on the sedimentological analysis of shallow marine reservoirs from the Upper Cretaceous Lower Grudja reservoirs from the Sasol-operated, Pande and Temane fields of the Southern Mozambique basin. Conventional cores were acquired as part of the various exploration and appraisal drilling campaigns and although of highly variable quality, they can be used for sedimentological analysis and calibration of petrophysical and reservoir properties for the main reservoir sands, informally named in sequential order from the G6 to G12. This core viewing opportunity focuses on both legacy and recent conventional whole core acquisition from the G6 reservoir in Pande and G8 reservoirs in Temane Fields. The key sedimentological features and trends will be demonstrated along with how the core data is used for calibration of petrophysical properties and the basis for reservoir characterisation studies. In addition, the process of preserving this invaluable data source for the benefit of future use will be highlighted.
