Formation evaluation and assessment of flow units of some selected wells in the Bredasdorp basin, offshore South Africa

Abstract

Petroleum geologists have long recognized the need to apply secondary and tertiary hydrocarbon recovery techniques for an accurate understanding of the internal architecture of a reservoir. The approach to effective incorporation of geological heterogeneity in numerical models for stimulating reservoir behaviour, detailed petrophysical zonation and mineralogy composition analyses are required. These include the delineation of sandstone reservoirs and characterization of the sedimentological and petrophysical properties into a system for reservoir description in the Gas Field, the grouping of rock units into flow zones from core porosity and permeability and understanding of the effects of minerals on reservoir flow zones for the assessment and construction of the flow units.
