1. An apparatus for conducting a formation test comprising:
- a carrier conveyable into a well borehole;
a formation test tool coupled to the carrier, the formation test tool including a seal that engages a borehole wall;
a measurement device that estimates a seal parameter during operation; and
a processor configured to use a seal model to estimate a system volume change resulting at least in part from a change in the seal during a downhole operation, wherein using the seal model includes correlating the seal parameter to the seal model to estimate the system volume change.

Abstract
A method for conducting a formation test includes providing a volume change model for a tool component, and providing a control program that uses the volume change model to estimate a system volume change resulting from a change in the tool component during a downhole operation. An apparatus for conducting a formation test includes a carrier, a formation test tool, a measurement device that estimates a change in a tool component during operation, and a processor that uses a volume change model to estimate a system volume change resulting at least in part from the change in the tool component during a downhole operation.

13. A method for conducting a formation test comprising:
-
conveying a tool in a well borehole; contacting a subterranean formation with a seal disposed on the tool to establish fluidic communication with the subterranean formation; conducting a formation test operation estimating a seal parameter during the formation test operation; and estimating a volume change using a seal model that relates a change in the seal to a system volume, wherein using the seal model includes correlating the seal parameter to the seal model to estimate the system volume change. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
