Abstract: A technique for monitoring valve and pump efficiencies for positive displacement pumps. The techniques include utilizing a data acquisition system to attain intake and discharge pressure data in combination with real-time encoder position data. Thus, when combined, output from a pump may be monitored in real-time. As a result, pump life may be extended beyond an anticipated changeout schedule. By the same token, premature pump inefficiencies may also be detected for taking a pump offline in advance of expected life. In either circumstance, multi-pump operations may be substantially enhanced with cost and time savings realized.

Abstract: A well operation facility including a first pump for delivering mud and cement to a borehole, a second pump for delivering mud to the borehole; a third pump for delivering the mud to the borehole, an inlet manifold coupled to each of the pumps for delivering the mud and/or cement to the pumps, and a discharge manifold coupled to each of the pumps for delivering the mud and/or cement at a pressure. In some embodiments, the first pump, the second pump, and the third pump are configured to be isolated from each other and to be used in series, parallel or as backups to each other.
