Abstract

A method for drilling a borehole penetrating an earth formation includes: drilling a first section of the borehole; notching a wall of the borehole in one or more selected locations with a selected type of notch using a notcher for defined local weakening of the formation; performing a local induced break-out test and/or local fracturing operation on an annulus section of the first section of the borehole between the drill string and a wall of the borehole using a test tool comprising a packer to provide formation stress-state data. The one or more locations is based on the formation stress-state data. The method further includes deriving stress-state of the formation and a fracturing parameter of the formation using the formation stress-state data and drilling a second section of the borehole using the derived stress-state and the fracturing parameter.
