Geological Modeling of Intrusive Bodies

A045 Geological modeling of intrusive bodies 1 S.A. PETERSEN N. SKJEI Norsk Hydro PO Box 7190 N-5020 Bergen Norway Summary A method for the construction of geological models is presented which includes the presence of intrusive bodies. The development was triggered by modeling studies of 4D seismic effects of sand intrusions above the Grane oil production field (North Sea). Structurally complex intrusion patterns are easily obtained and at any scale. The method is applicable to most types of intrusive bodies and in a way that allows several physical forward evaluations to be invoked (seismic induction log etc.). Introduction The Grane
