Experience: Continent-scale Interpretations
Dick Gibson created detailed, play-oriented interpretations of five continent-scale gravity and/or magnetic data sets for hydrocarbon exploration. The projects all included specific locations that were recommended as analogs to existing production, as well as areas that fit the tectonic setting of known or postulated plays. In some places, the work resulted in previously unstudied play concepts.
Work like this in Nevada, USA, resulted in a series of recommended exploration locations; one such site was the location of the later discovery of Grant Canyon Oil Field, with the most productive onshore well in the lower 48 states. For more information, click on any heading.
