Abstract:The gravity stripping technique has been described several decades ago as a valuable tool for geophysical exploration of deeper geological structures in old oil fields. It has been tested in a 3D approach in a suitable area located in the Moesian Platform, Romania, in a region with old oil fields. The new stripped gravity map offers information on the geological structures situated beneath the stripping surface, meaning depths situated between 3,000 and 6,000 m in the testing area. The newly contoured gravity anomalies may be associated with basic or acidic magmatic rocks within the basement and with folded or uplifted sedimentary structures, associated with oil and gas accumulations.
