Clay minerals are one of the most important groups of minerals that
destroy permeability in sandstones. However, they also react with
drilling and completion fluids and induce fines migration during
hydrocarbon production. They are a very complex family of minerals
that are routinely intergrown with each other, contain a wide range
of solid solutions and form by a variety of processes under a wide
range temperatures and rock and fluid compositions.
In this volume, clay minerals in sandstones are reviewed in
terms of their mineralogy and general occurrence, their stable and
radiogenic isotope geochemistry, XRD quantification, their effects
on the petrophysical properties of sandstones and their
relationships to sequence stratigraphy and palaeoclimate. The
controls on various clay minerals are addressed and a variety of
geochemical issues, including the importance of mass flux, links to
carbonate mineral diagenesis and linked clay mineral diagenesis in
interbedded mudstone-sandstone are explored. A number of case
studies are included for kaolin, illite and chlorite cements, and
the occurrence of smectite in sandstone is reviewed. Experimental
rate data for clay cements in sandstones are reviewed and there are
two model-based case studies that address the rates of growth of
kaolinite and illite.
The readership of this volume will include sedimentologists and
petrographers who deal with the occurrence, spatial and temporal
distribution patterns and importance of clay mineral cements in
sandstones, geochemists involved in unraveling the factors that
control clay mineral cement formation in sandstones and petroleum
geoscientists involved in predicting clay mineral distribution in
sandstones. The book will also be of interest to geologists
involved in palaeoclimate studies basin analysis.Latest geochemical
data on clays in sandstonesProvides important information for
geologists involved in basin analysis, sandstone petrology and
petroleum geology
