Abstract
A method for producing a substantially calibrated numerical model, which can be used for calculating a stress on any point in a formation, accounts for a formation's geologic history using at least one virtual formation condition to effectively 'create' the present-day, virgin stress distribution that correlates, within acceptable deviation limits, to actual field stress measurement data obtained for the formation. A virtual formation condition may describe an elastic rock property (e.g., Poisson ratio, Young's modulus), a plastic rock property (e.g., friction angle, cohesion) and/or a geologic process (e.g., tectonics, erosion) considered pertinent to developing a stratigraphic model suitable for performing the desired stress analysis of the formation.
