Systems and methods for continuously monitoring mass loss through flow erosion of a well equipment component are provided. The disclosed system includes a wear transducer mounted to the equipment component proximate a portion of the equipment component exposed to erosive fluid flow. The wear transducer includes a metal coupon including an elongated end that extends into a flowpath of the equipment component such that the elongated end is exposed to the erosive fluid flow. The wear transducer also includes an ultrasonic sensor disposed within the metal coupon. The ultrasonic sensor transmits ultrasonic signals through the metal coupon toward the elongated end and receives ultrasonic signal reflections reflected back from the elongated end.

A method can include deploying a diverter plug into a well, the diverter plug comprising a group of particles that are prevented from dispersing, flowing fluid, thereby conveying the diverter plug into engagement with a fluid passageway, the particles conforming to a shape of the fluid passageway as the diverter plug blocks fluid flow through the fluid passageway, and the particles being prevented from dispersing while the diverter plug blocks the fluid flow through the fluid passageway. The diverter plug can include a group of particles disposed within an outer enclosure. The particles in the enclosure can conform to a shape of the fluid passageway as the diverter plug blocks fluid flow through the fluid passageway. In another method, the enclosure can sealingly engage the fluid passageway while the particles remain disposed within the enclosure.

A cement head is disclosed that includes a cement head body that houses a moveable cage which protects a cement plug until the cement plug is released into a cement flow path. The cage is moveable between a first position in which cement slurry flows around the cage, and a second position in which cement slurry flows through the cage to facilitate launch of the cement plug into a wellbore. The cage may include a lifting device to assist with moving the cage from the second position to the first position after launch of the cement plug. The cement head may be a modular design that includes multiple cement head bodies, and may also include a pressure balanced plug launch indicator and torque keys.

A method of performing an annular cementing operation after setting an integrated hanger and seal includes introducing a tubular including a flow passage having an inlet and an outlet into a wellbore, positioning and setting the integrated hanger and seal in the tubular, flowing cement between the tubular and the integrated hanger and seal into the inlet of the flow passage, passing the cement through the flow passage to the outlet, flowing the cement from the outlet, and closing the outlet.

A well plug, comprising a cylindrical body, a plurality of cylindrical fins encircling the cylindrical body, a concrete core disposed within the cylindrical body and a locking feature disposed in the concrete core and configured to lock with an adjacent well plug.

A tool for launching wiper plugs into a casing string in a gas or oil well during cementing operations employs a collet-like mechanism carrying radially-movable jaws arranged to retain a plug in a fluid flow path when the tool is in a closed position, and to release the plug into the fluid flow path when the tool is in an open position. Selection of the desired operational position of the plug launcher (i.e., open or closed) is effected by actuation of an axially-movable sliding sleeve. Alternative means for actuating the sliding sleeve include rotary actuation about the tool's longitudinal axis, rotary actuation about a radial axis generally normal to the longitudinal axis, rotary actuation about a generally tangent axis, and pneumatic or hydraulic actuation. The tool may be adapted to carry multiple wiper plugs for sequential launching into a casing string.
