Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of estimating stress in an earth formation, comprising: generating with a processing unit a domain including at least a portion of the earth formation based on sensor data for the formation; discretizing the domain into a plurality of cells, each cell including a respective density value being representative of a selected location in the domain; dividing the domain including at least the portion of the earth formation into a first region and a s…
