The youngest Guadalupian shelf deposits in the Permian Basin region of West Texas and southeastern New Mexico are exposed in the Tansill Formation in East Dark Canyon, Guadalupe Mountains, New Mexico (Figs. 1 and 2). Previous investigations of the Capitan Limestone have suggested that Ochoan deposition was foreshadowed by Delaware Basin shallowing conditions (Babcock, 1974; Toomey and Babcock, 1983) and increasing restriction of basinal and shelf waters (Given and Lohmann, 1985) at the end of the Guadalupian. The deposits of the middle and uppermost Tansill Formation (Tyrrell et al., 1978) in East Dark Canyon provided the opportunity to describe and interpret the latest pulses of Guadalupian back-reef sedimentation in the barrier-island complex of the shelf.

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.
