IN-SITU FORMATIONS STRENGTH TESTING WITH FORMATION SAMPLING

摘要

A method and apparatus for estimating a property include evaluating a formation at a formation evaluation location using a formation evaluation tool, and estimating the property at least in part by engaging a borehole wall substantially adjacent the formation evaluation location with a formation strength test device. In one aspect, an apparatus for estimating a property may include a carrier conveyable in a borehole to a formation. Two or more packers may be used to isolate an annular zone about the carrier, and a formation evaluation tool may be disposed on the carrier, the formation evaluation tool adapted to evaluate the formation at a formation evaluation location.
