This paper provides insight into the importance of knowing the minerals present in the reservoir, particularly the total clay percentage. It is vital to know the types and percentages of clays present for effective reservoir treatment and analysis. During the evolution of a petroliferous sedimentary basin, the clay minerals contained in the rocks undergo a series of changes in composition and crystal structure in response to tectonics and sedimentation. The amount and type of clay minerals are a function of the provenance of clastic minerals and of diagenetic reactions at shallow and greater depth in different tectonic and sedimentary settings. Clay minerals can be used to infer tectonic/structural regime, basin evolution history, and the timing of various geologic events. (no extended abstract available) |
