Elwood... I did use a poor choice of words when I stated "most of the worlds largest oil fields are stratigraphic traps". A better word would be "many are stratigraphic".
Yes, Gharwar and Burgan and several other giant fields are primarily structural/anticline fields. Even these large features have pinch-outs in various zones. This is also common on most anticlines..even on a much smaller scale like the Nesson Anticline in North Dakota where updip stratigraphic changes have created numerous traps (fields)in several producing horizons. -------------- Reference source: Nontechnical Guide to Petroleum Geology, Exploration, Drilling, and Production By Norman J. Hyne Published by PennWell Books, 2001 ISBN 087814823X, 9780878148233 598 pages Dr. Hyne (page 181) credits the two largest fields in North America, East Texas and Prudhoe Bay as both being stratigraphic traps. ------------ A "Google" search for the worlds largest stratigraphic fields proved to very interesting. Let's hope the Bakken will become a part of that exclusive group! I guess the important point is that it takes many different geologic features to make oil fields of all sizes. Where ever they might be, it takes skill and dollars to find and develop them. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Bakken Shale Discussion" group.
