In this report the wide variability in structural styles within the growth-faulted, geopressured trends of the Texas Gulf Coast is illustrated by detailed structural maps of Wilcox and Frio growth-fault trends and quantified by statistical analysis of fault compartment geometries. Within the Frio growth-fault trend the Sarita, Corpus Christi, and Port Arthur areas, together with the previously studied Blessing and Pleasant Bayou prospects, span nearly the entire range of Frio depositional systems. The Frio and Wilcox growth-fault trends show distinct differences. The author concludes that Wilcox sandstones tend to be dip-elongate, whereas fault compartments are highly strike-elongate; the probability of large reservoirs is consequently low. Frio sandstones are of mixed geometry, and fault compartments are larger and more equant, suggesting an increased chance of finding large reservoirs.
