Abstract
Embodiments presented provide for stress testing of downhole wireline formation testing equipment. Certain embodiments provide for stress testing of geological stratum which exhibit high permeability.
Claims10
A method to perform a stress test on a geological formation, comprising:
- conveying a bottom hole assembly on a drill pipe to a testing location;
- setting at least two packers at the testing location in a wellbore;
- performing an injection of a fluid obtained from the drill pipe into the testing location in the geological formation;
- stopping the injection of the fluid from the drill pipe;
- performing at least one breakdown cycle injection with the fluid from the drill pipe;
- determining when the at least one breakdown cycle injection with fluid results in an open reservoir;
- performing an injection followed by falloff cycles using downhole-based equipment into the geological formation;
- and
- deflating the at least two packers.

A method to perform a stress test on a geological formation, comprising:
- conveying a bottom hole assembly on a drill pipe to a testing location;
- setting a dual packer at the testing location in a wellbore;
- performing an injection of a solids-free fluid obtained from the drill pipe into the testing location in the geological formation;
- stopping the injection of the fluid from the drill pipe;
- performing at least one breakdown cycle injection with the fluid from the drill pipe;
- performing an injection propagation cycle with the bottom hole assembly using the solids-free fluid;
- determining when the at least one breakdown cycle injection with fluid results in an open reservoir;
- performing an injection followed by falloff cycles using downhole-based equipment into the geological formation when the open reservoir is determined;
- and
- deflating the at least two packers.
