Subsurface modeling from seismic and borehole data is important for reservoir prediction, geophysical exploration, and production. A reasonable model should honor borehole rock properties and conform to seismic structural and stratigraphic features. Such a subsurface model can be difficult to build in cases complicated by faults and unconformities. Automatic and semiautomatic methods have been ...

Fluid circulation at fractured basement/cover unconformity is of first importance for geothermal energy exploitation especially in continental rifting as the Upper Rhine Graben. This unconformity presents lot of natural fractures which constitute a large permeable fracture network driving brine movement. That constitutes a reservoir of hot water, which is exploited by several geothermal power p...

The energy crisis has created increased interest in petroleum exploration. Discoveries of major deposits are increasingly rare and difficult to locate. The geophysicist requires more accurate knowledge to assist him in locating deeper and smaller hydrocarbon deposits. While gravity, magnetic, and electrical methods are also used, the predominant exploration tool is the seismic method and provid...

Over recent decades, electromagnetic methods have been viewed with considerable suspicion by many in the hydrocarbon exploration industry. While highly effective in mineral and environmental geophysics, electro m a g n e t i c methods have played a minor role in hydrocarbon exploration. Since electromagnetic (EM) methods use signals that diffuse in the Earth, they cannot provide the same vertic...
