It is obvious that the results of exploratory onshore efforts in the last decade--which have been directed toward structural anomalies--have not been generally successful. Yet, the industry continues to neglect the purposeful search for stratigraphic and paleogeomorphic traps even though some of the largest oil and gas fields in the world are in such reservoirs. As explorationists it is our responsibility to originate new ideas, new methods, and arrive at a decisive "breakthrough" of some kind to discover these so-called subtle traps. Because these traps occur in a great variety of possible geologic environments--such as relic shorelines, channels, deltas, lagoons, river and stream beds, buried overlaps and onlaps, and in other ancient topography--ranging in size from inc nsequential to supergiant--the industry is shirking its duty to the nation if it does not embark immediately on an extensive and concentrated effort to focus all of its exploration know-how toward searching for and finding the large petroleum reserves which surely exist in these subtle traps.
