【 摘 要 】

Because reservoir production is primarily in fractured rock, a great deal of effort has been spent devising means of remotely sensing fractures and fracture zones using geophysics. Since increased fluid content or alteration of fractures can give rise to an electrical conductivity contrast, electromagnetic (EM) means of probing have been investigated extensively over the years. Although direct and indirect fracture responses have been noted in many field situations, a fracture response can be subtle and progress has been sporadic. The purpose of this project was to facilitate inductive fracture detection by providing the interpretation tools and knowledge-theoretic frame work for innovative high resolution fracture detection and delineation.
