Lower Cretaceous sandstones of the Muddy Formation have produced a number of significant hydrocarbon reservoirs in the Powder River Basin. These reservoir sandstones accumulated in a variety of fluvial, deltaic, and shallow marine environments. The porosity and permeability of Muddy sandstones are affected significantly by the amount and composition of diagenetic clay minerals. Diagenetic clay mineral assemblages within the Muddy are time controlled. Oldest Muddy sandstones (zones 5 and 6) are characterized by a kaolinite-chlorite-illite-quartz assemblage with sporadic chlorite and illite. Youngest Muddy sandstones (zones 1 and 2) are characterized by a kaolinite-quartz assemblage. This diagenetic time-trend is matched by a change in the composition of detrital components. Older Muddy sandstones are more feldspatic, contain more rock fragments, and less quartz than the younger sandstones. Well-stimulation and completion treatments should take into account the diagenetic assemblages present in the reservoir sandstones.
