This study is a detailed, play-oriented interpretation of published gravity and magnetic data from the conterminous United States. It is intended as a guide to play and prospect generation in both frontier and mature hydrocarbon exploration provinces. For example, analysis of the Mid-Continent Gravity Anomaly (above) can suggest where basement structures of the Precambrian rift system have affected overlying strata. In Kansas, there appears to be a clear relationship between inferred rift-related basement faulting and long, narrow oil fields.
Products of the study include detailed interpretations in
24 areas. The scope and details of each area vary due to the
information content of the data. For example, interpretation
and play maps of the Black Warrior Basin are at a scale of 1:2,500,000,
while the maps of Nevada and Montana are at 1:500,000. In areas
that are mapped at relatively large scale, recommendations are
nearly at the prospect level.
Thirty separate interpretation and play maps accompany the report, which consists of a 160-page text including 52 figures. Some of the plays and interpretations are given as text figures if appropriate. More than 150 specific locations are recommended for various levels of further exploration.
This project represents six months of intense work, drawing on years of interpretation experience. The work was done by Richard I. Gibson when he was Director of Gravity and Magnetics for Everest Geotech, Inc. Gibson Consulting has all rights to this study. The work was supported initially by three clients.
Price
The complete package, including reproducible copies of the interpretation maps
and a set of the published maps on which the intepretations were
based, is available. Cost is $10,000. Basin-scale subsets, updated with a look at any newer published data, are also available.
