This paper was compiled as part of a laboratory exercise for a graduate course, co-taught by Roger Slatt and Paul Weimer, entitled, "Petroleum Geology of Turbidite Systems." In compiling the information in the paper, we have spoken with many people who kindly supplied us with nonproprietary information about the fields. We are grateful to the following people for their help: Robert Bunch (Mobil), Wayne Camp (Anadarko), John Dombrowski (Texaco), Ben Funderburk (Forest), Peter Gale (British-Borneo), Gary Guthrie (Marathon), William Holman (Newfield), Mike Jobe (Walter Oil), Todd Jones (Newfield), Michael Joseph (Texaco), Alan Kornacki (Shell), David Lawrence (Shell), Mike Mahaffie (Shell), Vinod Mathur (Mobil), William Mills (BP), Clint Moore (Anadarko), John Pike (Tathum), John Rafalowski (Chevron), David Robertson (Forest), Tricia Santogrossi (Vastar), William Schneider (Conoco), Kevin Schofield (Conoco), Roger Shew (Shell), Mike Smith (CNG), Mike Strickler (Texaco), Scott Tinker (Marathon), Brian Wallick (Mobil), David Walz (CNG), Tom Wilson (Shell), and Kris Wojcik (Shell). We thank Mark Rowan for his help with the structural interpretations shown here. We extend special thanks to Halliburton Geophysical (now Western Geophysical), specifically to Bob Graebner, John Anderson, and Gary White, for the seismic data used in this project. We are indebted to PaleoData Inc. and Art Waterman for use of their biostratigraphic data. Digital logs were kindly provided by Marathon (Tricia Santogrossi). We thank Davis Ratcliff and Diamond Geophysical, SEPM, and the Gulf Coast Section SEPM Foundation for their permission to reprint figures shown here. We thank Kevin Biddle (former AAPG elected editor), and AAPG reviewers Brad Prather and Denise Stone for their reviews of an earlier version of this paper, although we alone are responsible for the interpretations presented here. Acknowledgment is made to the donors of the Petroleum Research Fund, administered by the American Chemical Society, for partial support of this work. 

ABSTRACT

Thirty-five fields and discoveries from the northern Green Canyon, Ewing Bank, and southern Ship Shoal and South Timbalier protraction areas (offshore Louisiana) are characterized by a series of seismic profiles, wireline logs, and summaries of their production characteristics. All fields or discoveries consist of combined structural/stratigraphic traps. Reservoirs occur in various elements of turbidite systems-primarily in sheet sands, channel fill, and thin beds. Best production rates occur in sheet sand facies. Development facilities vary from fixed platforms to subsea tiebacks to existing fields.
