Abstract: A downhole isolation tool includes a mandrel made of non-metallic material, the mandrel comprising an isolation region at a first end of the mandrel, a shear sleeve adapter disposable on an outer surface of the isolation region, the shear sleeve adapter having holes aligned with holes in the outer surface of the isolation region, a slip assembly positioned around an outer surface of the mandrel, a packing element positioned around the outer surface of the mandrel, and a shoe positioned around the outer surface of the mandrel at a second end of the mandrel.

Abstract: A downhole isolation tool adapted to be converted in the field into any one of a bridge plug, ball drop plug, or a caged ball plug. The components used to assemble the tool, such as the mandrel, slips, and conversion adapters and accessories, are constructed primarily of non-metallic material. Through use of the disclosed isolation tool, drillout time is greatly reduced.

Abstract: A slip assembly adapted to be used with a downhole tool which comprises metal slip inserts attached to a slip carrier made of a non-metallic material, such as composite material. As such, the non-metallic slip carrier can eliminate 60-70% or more of the metal used in conventional slip assemblies. Through use of the disclosed slip assembly, downhole tools may be set, while also reducing the metallic material used therein and, thus, greatly reducing the drill out time.

Abstract: The check-in station is a stand alone, vertically-oriented unit which generates key cards. The unit employs a touch screen connected to a processor and a card encoding unit. The touch screen, processor and card encoding unit are arranged in the unit so as to provide a compacted, user friendly machine.

Abstract: The electric lock system combines an electric lock with an energy control unit such that when a guest key is used in the lock, the lock communicates with the energy control unit to move from an unsold state to a sold state. Optionally, the guest key has information which tells the lock when the guest will leave and the lock communicates to the energy control unit to move from the sold state to an unsold state. Another option, includes a motion detector and door switch which allows the lock to detect the presence of the guest in the room and allows the lock to further employ an occupied and unoccupied state. The combination of the electric lock system and the energy control unit provides energy savings in the heating and cooling of the room.

Abstract: The electric lock system operates to block access to the room when a guest key has been used and the guest is detected as being present in the room. The lock blocks access to hotel staff and provides the guest greater privacy in the room. The lock system employs an electronic lock in combination with a motion detector for detecting the presence of the guest in the room.
