Abstract: A method, according to one or more aspects of the present disclosure, for calibrating a pump assembly includes characterizing one or more pumps of the pump assembly to determine one or more performance characteristics of the one or more pumps. The method may also include calibrating a sensor associated with a displacement unit of the pump assembly. Calibrating the sensor may include calibrating the sensor under operating conditions of a first environment and under operating conditions of a second environment. Under the operating conditions of the second environment, the one or more pumps can also be to determine one or more performance characteristics of the one or more pumps at the operating conditions of the second environment.

The method may also include calibrating a sensor associated with a displacement unit of the pump assembly. Calibrating the sensor may include calibrating the sensor under operating conditions of a first environment and under operating conditions of a second environment. Under the operating conditions of the second environment, the pump can also be calibrated to determine a performance characteristics of the pump at the operating conditions of the second environment. The calibrated pump assembly is then used to draw fluid from a subterranean formation or conduct a formation test.

Abstract: A method to detect flow rate from a displacement unit entailing locating the displacement unit in a fluid path, monitoring a piston position in the displacement unit for a stroke direction change, starting a timer upon a stroke direction change, monitoring at least one check valve position for an alteration of position, stopping the timer upon the alteration of position, calculating a time between the stroke direction change and the alternation of position, calculating a volume of the displacement unit and calculating the flow rate from the displacement unit by dividing the volume of the displacement unit by the calculated time.

CPC classification number: E21B49/081 , E21B49/10
Abstract: A downhole sampling tool includes a cam configured to rotate about a central axis. Two or more pistons engage a cam track such that rotation of the cam causes the pistons to reciprocate between first and second piston positions. Corresponding fluid flow lines are opened and closed when corresponding ones of the plurality of pistons reciprocate between the first and second piston positions.
