A sub having an anti-rotation feature for a resource exploration and recovery system includes a tubular having an outer surface and an inner surface defining a flow bore. A sleeve is slideably disposed in the flow bore between a first position and a second position. The sleeve includes an inner surface portion having a taper. A dart including an end portion is disposed in the sleeve. The dart is configured to shift the sleeve between the first position and the second position when exposed to a selected pressure in the flowbore. The end portion includes a tapered section. The tapered section mating with the taper formed in the inner surface to rotatably lock the plug to the inner surface of the sleeve.

Wiper plug system with anti-rotation feature

A liner plug assembly includes liner plug for use in a casing. The liner plug includes a body for plugging the casing and a body fragmentation feature in the body for catching a cutter of a drill bit used to cut the body. The liner plug assembly includes the lead plug.

Cement plug fragmentation enhancement

A plug system includes a locked member of a first plug and a free member of a second plug. The locked member has a first locking end having a first anti-rotation feature. The free member has a second locking end having a second anti-rotation feature. The first anti-rotation feature and the second anti-rotation feature are configured to fit together to resist a rotation between the free member and the locked member to thereby resist rotation of the second plug with respect to the first plug.
