Method and apparatus for formation testing
First Claim
1. A method for conducting a formation test comprising:
- calculating, by a processor, a correction factor based on a system volume change, the correction factor configured to be used to compensate for the system volume change, andestimating the system volume change based on a change in a parameter of a tool component.

Abstract
A method includes calculating a correction factor that uses a tool component volume change model to estimate a system volume change resulting from a change in the tool component. An apparatus includes a carrier conveyable into a well borehole, a formation test tool coupled to the carrier, the formation test tool including a tool component. A measurement device to estimate a change in the tool component during operation, and a compensator uses an estimated system volume change resulting at least in part from the change in the tool component during a downhole operation, the compensator compensating for the system volume change and wherein the estimated system volume change is estimated at least in part using a volume change model.

6. 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 tool component; a measurement device that estimates a change in a parameter of the tool component during operation; a processor configured to estimate at least in part a system volume change by correlating the change in the parameter to a volume change model; and a compensator that uses the estimated system volume change resulting at least in part from the change in the tool component during a downhole operation, the compensator configured to compensate for the system volume change. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for conducting a formation test comprising:
-
conveying a tool component into a borehole; contacting a formation with the tool component to establish fluidic communication with the formation; conducting a formation test operation; estimating a change in a parameter of the tool component; and estimating at least in part a system volume change by correlating the estimated change in the parameter of the tool component to a volume change model and compensating for the system volume change via a processor. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
