Abstract
A method for obtaining a maximum horizontal stress at a depth of a geological formation, includes: setting an estimate Sof the maximum horizontal stress; conducting an elastoplastic modeling simulation of the geological formation around a wellbore with the estimate Sand obtaining a simulated value ϕof a breakout angle, wherein the breakout angle is a half-width of a breakout region; and upon determining that the estimate ϕis greater than or equal to a prescribed value and is different from a measured breakout angle ϕat the depth by more than a threshold value, repeatedly changing the estimate Sand conducting the elastoplastic modeling simulation.
