1. A system for testing a core sample, comprising:
- a non-permeable sleeve configured to be placed over a core sample;
a first pair of opposing actuators to apply opposing force to the non-permeable sleeve in a first axis normal to an axis of the core sample;
a second pair of opposing actuators to apply opposing force to the non-permeable sleeve in a second axis normal to the axis of the core sample and normal to the first axis;
a wellbore pressure reservoir to provide simulated wellbore pressure; and
a formation pressure reservoir to provide simulated formation fluid pressure.

14. A system for testing a core sample, comprising:
-
a non-permeable sleeve placed over the core sample; a permeable sleeve adhered to the core sample, wherein the non-permeable sleeve is positioned over both the permeable sleeve and the core sample, wherein a flow impedance of each of a plurality of portions of the permeable sleeve is based on an impedance map; a first pair of opposing actuators to apply opposing force to the non-permeable sleeve in a first axis normal to the axis of the core sample; a second pair of opposing actuators to apply opposing force to the non-permeable sleeve in a second axis normal to the axis of the core sample and normal to the first axis; a wellbore pressure reservoir to provide simulated wellbore pressure; and a formation pressure reservoir to provide simulated formation fluid pressure. - View Dependent Claims (15, 16, 17, 18, 19, 20)
