Abstract:
An improved method for determining the magnitude of the minimum principle horizontal stress within a formation is disclosed and claimed herein. In particular, the inventive method involves the use of a wireline retrievable circumferential acoustic scanning tool during an open hole microfracture test to determine the magnitude of the minimum principle horizontal stress in the formation.
