Magnetic basement mapping in petroleum exploration can be applied to the search for leads or prospects that can be quickly and economically developed by comparing known traps or structure (and/or stratigraphy) with the basement fault block pattern. Some areas have never been tested by the drill where the structure at basement level is analogous to that over nearby producing properties. Some of these leads become viable prospects when subjected to follow-up seismic profiling or other appropriate exploration techniques. A common type of structural or stratigraphic data used to correlate to the magnetic data is subsurface mapping, developed from well data. However, on overseas projects or in frontier areas, the best (or only) data available may be 2-D seismic surveying. In either case, the procedure is to search for “look-alikes” on the magnetic data that correspond to features over known producing fields. Since the magnetic data can be acquired in continuous fashion over large areas at a very economical price, many good leads can be developed in a short time.
