Abstract: Detecting a failure mode of a fluid flow controller configured to control fluid flow between first and second chambers of a downhole positive displacement pump and a flow line, wherein the positive displacement pump comprises a piston moving in an axial reciprocating motion, and subsequently adjusting operation of the downhole positive displacement pump based on the detected failure mode such that the downhole positive displacement pump piston operates differently in different axial directions.

Abstract: A method for monitoring a condition of at least one valve positioned with respect to at least one of a first chamber and a second chamber of a reciprocating compressor is provided. The method includes establishing a compressor operation cycle including a valve opening event, a valve closing event and/or a rod reversal event. A crank angle is determined at each of the valve opening event, the valve closing event and/or the rod reversal event during the compressor operation cycle using at least one of a static pressure input and a machine speed input. The method further include diagnosing a valve leak condition during the compressor operation cycle at the valve closing event, wherein the at least one valve is closed.
