System and method for determining mechanical properties of a formation

摘要

A method and/or a system determines mechanical properties of a fluid-bearing formation. One or more packers may be used to measure and/or collect data regarding mechanical properties of a formation. The formation characteristics may be, for example, the stability of the formation, design parameters for frac-pack/gravel-pack operations, and sand production. The packer may expand within a wellbore of a formation until enough pressure is applied to fracture a wall of the wellbore. Before, during and/or after the fracturing of the wall, multiple measurements may be taken by the packer. After fractures are initiated, fluid may be pumped into and/or drawn from the formation using drains disposed on the packer. Additional packers may be used above and/or below the packer for isolating intervals of the wellbore.

1. A method comprising:
deploying a packer into a formation; inflating the packer against a wall of the formation until fractures are initiated in the wall; propagating the fractures by pumping fluid into the fractures from drains disposed on the packer; and measuring data related to the formation.
