Title: Method for determining the minimum principle horizontal stress within a formation through use of a wireline retrievable circumferential acoustic scanning tool during an open hole microfrac test

Abstract

A method is described for determining the magnitude of the minimum principle horizontal stress within a formation having an open hole well bore formed therein, comprising the steps of: supplying pressurized fracturing fluid to said well bore in a desired area of observation, said well bore exposing an interior surface of said formation; inserting a circumferential acoustic scanning tool into said well bore and positioning said tool in said area of observation, said acoustic scanning tool providing a viewable image of said interior surface of said formation; increasing the pressure on said fracturing fluid until fractures are initiated in said formation proximate the well bore; increasing the pressure acting on said fracturing fluid so as to cause said initiated fractures to further open; observing the interior surface of said formation during said opening of said previously initiated fractures; and noting the magnitude of the pressure acting on said fracturing fluid as said previously initiated fractures are opened.
