Abstract
Summary
Three-dimensional pore pressure modelling over geological time scale has been carried out for a deeply buried possible reservoir in the Vana and Volve Sub-Basin, Viking Graben. The magnitude of the minimum horizontal stresses has been varied, and the input stress gradient has been calibrated with observed Leak-Off Tests. The simulation results show varying misfit to observed overpressures in different wells. The methodology can in future be used with a Monte-Carlo approach.
