Abstract

The Devonian Jauf sandstones in Ghawar field show highly variable reservoir quality. The best sandstones have well preserved intergranular porosity due to the presence of radial illite coatings which retarded quartz cementation, but some wells are tight due to pervasive authigenic clay matrix. K-Ar dating shows that the radial illite formed between 81-121 Ma, although it could be a recrystallization of an earlier, possibly smectitic clay coat.
