Abstract
A method of estimating stress in an earth formation is disclosed. The method includes: dividing a domain including at least a portion of an earth formation into a first region and a second region; estimating a first vertical stress in the first region and representing the first vertical stress as at least one point load; estimating a second vertical stress in the second region by a point load based method using the first vertical stress; and estimating at least one horizontal stress based on the second vertical stress.
