The impact of detrital minerals on reservoir flow zones in the North Eastern Bredasdorp basin, South Africa, using core data. Minerals, 12(8), 1009. 10.3390/min120810092075-163X10.3390/min12081009http://hdl.handle.net/10566/7968The present study uses core data to group reservoirs of a gas field in the Bredasdorp Basin offshore South Africa into flow zones. One hundred and sixty-eight core porosity and permeability data were used to establish reservoir zones from the flow zone indicator (FZI) and Winland’s methods. Storage and flow capacities were determined from the stratigraphy-modified Lorenz plot (SMLP) method. The effects of the mineralogy on the flow zones were established from mineralogy composition analyses using quantitative X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Results reveal five flow zones grouped as high, moderate, low, very low, and tight reservoir rocks.enMineralsMineralogyFlow zoneBredasdorp BasinHydrocarbonArticle
