Abstract: A technique facilitates positively centering a well component, e.g. a downhole tool and/or coiled tubing, inside a pressure barrier, e.g. a riser. A centering device is positioned along the pressure barrier to move the well component toward a center of the pressure barrier. The centering device has a movable member, e.g. a plurality of movable members, selectively shiftable between a radially outward position and a radially inward position within the pressure barrier component. The well component is moved toward the center of the pressure barrier during shifting of the movable member(s) toward the radially inward position.

Abstract: Pumps for conveying fluid at a wellsite, such as fracturing or other stimulation pumps, are instrumented with sensors to measure or estimate pump parameters. In some instances, pump sensors are used to detect wear or failure or assess remaining useful life of pump components. The sensors can also or instead be used to assess, and in some cases optimize, pump performance.
