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.
