Eugene Island block 330 oil field

Eugene Island block 330 oil field is an oil field in the Gulf of Mexico 70-85 miles off the Louisiana coast. The oil field is best known for the controversy surrounding its depletion rate. According to the article "Sustainable Oil?" by Chris Bennett:

:"A significant reservoir of crude oil was discovered nearby in the late ’60s, and by 1970, a platform named Eugene 330 was busily producing about convert|15000|oilbbl/d|m3/d of high-quality crude oil. By the late ’80s, the platform’s production had slipped to less than convert|4000|oilbbl/d|m3/d, and was considered pumped out. Done. Suddenly, in 1990, production soared back to convert|15000|oilbbl/d|m3/d" [ http://www.wnd.com/news/article.asp?ARTICLE_ID=38645 Chris Bennett, "Sustainable Oil?", WorldNetDaily.com, May 25, 2004]

However, the figures given by Richard Heinberg are:

:"Production from Eugene Island had achieved convert|20000|oilbbl/d|m3/d by 1989; by 1992 it had slipped to convert|15000|oilbbl/d|m3/d|abbr=on, but recovered to reach a peak of convert|30000|oilbbl/d|m3/d|abbr=on in 1996. Production from the reservoir has dropped steadily since then."

The source of additional oil was analyzed as migrating through faults from deeper and older formations below of probable Jurassic and Early Cretaceous age. The oil contains biomarkers closely related to other very old oils and was long trapped in deep formations. [Robert Cooke, "Oil Fields Are Refilling...Naturally - Sometimes Rapidly", Newsday 2002]

Eugene Island 330 has been cited as an example of abiogenic petroleum origin, which holds that petroleum reservoirs are continuously replenished from inorganic sources deep within the Earth. However, Eugene Island 330's fame comes precisely from its status as an unusual anomaly, rather than being typical of the other 40,000 developed oil fields, and most petroleum scientists believe that the depletion profile is adequately explained by replenishment from deeper reservoirs of normal biologically derived petroleum.

In regard to oil depletion concerns, while the rate went up again in the early 1990s along with the overall estimated recoverable petroleum, the rate has since declined.
