Subsurface and Outcrop Examination of the Capitan Shelf Margin, Northern Delaware Basin

Shelf sandstone reservoirs are becoming a more and more common exploration target. What they are, how they may be characterized, and how they differ from shoreline and deep-water deposits in the subject of this publication. Shelf sands and sandstone reservoirs are among the more poorly understood types of sandstones. Continental, shoreline and deep water sandstones have all been studied in much more depth than have shelf sands and sandstones. However, during the last fifteen years significant progress has been made in understanding shelf sands and sandstones. Studies of modern sediments have allowed us to understand many of the depositional processes active on the shelf. This book is intended to be an up-to-date summary of shelf processes and products. The papers are intended for those new to shelf sands and sandstones as well as the shelf specialist.

Abstract
This paper summarizes an ongoing research project on the Delaware Basin studying interrelationships between oil-gas, sulfur deposits, Mississippi Valley-type (MVT) ores, and cave genesis. Such an integrated approach was taken by Hill (1987), who suggested that basinal H2S - generated by oil-anhydrite reactions at the Castile-Bell Canyon contact - was the ultimate source for the sulfuric-acid speleogenesis of Guadalupe caves and for MVT ores in carbonate rock along the margins of the basin.
