The disclosure relates to a method of evaluating characteristics of an earth formation, comprising deploying a packer assembly in a borehole penetrating an earth formation, the packer assembly comprising an instrumented inflatable packer element including fiber optic sensors; inflating the instrumented inflatable packer elements; detecting, using the fiber optic sensors, events occurring in the earth formation; and transmitting data corresponding to the detected events to a surface processing system. The disclosure also relates to a packer element and a instrumented packer assembly system. The disclosure may enable to derive formation characteristic in several configurations such as a stress test or a hydraulic fracturing configuration.

Instrumented packer having distributed fiber optic sensor

A method can include receiving well path data and geomechanical simulation data; rotating at least a portion of the geomechanical simulation data from geomechanical simulation coordinates to well coordinates associated with the well path data; determining at least one of an axial strain proxy and a shear strain proxy based at least in part on the rotating; and analyzing at least the one of the axial strain proxy and the shear strain proxy.

Well survivability in multidimensional geomechanical space

A method can include receiving data that characterizes anisotropy of a formation; receiving a model that models one or more planes of weakness in an anisotropic formation; and, based at least in part on the model and the data, outputting information germane to stability of a bore in an anisotropic formation.
