The present invention relates to clamping devices that connect to a fracking tool body and associated attached flow lines and the method of use thereof. More particularly, the present invention relates to clamping devices that connect to and stabilize a fracking tool body and associated attached flow lines that aid in locating and supporting the inlet connection allowing it to be closer to the rig floor, and consequently, making it safer to install the rest of the rig flow lines.

The hydraulic device is deactivated if the ratio varies from a preset value. One embodiment includes a plurality of flow meters for measuring fluid flow to and from one or more hydraulically powered apparatuses. In one embodiment outputs of the flow meters are analyzed to determine if the hydraulic system has a leak, and if a leak is detected, a warning is issued and/or one or more of the connected hydraulically powered apparatuses are shut down, and/or the hydraulic power supply is shut down. In one embodiment, the flow lines are jointed flow lines comprised of hose joints connected end to end. Some or all of the hoses have check valves. In one embodiment, the check valves stop flow in either direction if the flow pressure drops below a selected pressure.

Method and apparatus for dropping a pump down plug or ball
An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation.

A method of severing a well string that extends into an oil well from an oil platform with a deck includes supporting upper and lower sections of the well string, the lower section supported at the platform deck with a deck located string support. A shear mechanism cuts the well string at a position that can be above the deck located string support. The upper section is then lifted a selected distance and the deck located string support again supports the string at a position below the cut.

A hydraulic clamshell bucket apparatus employs a frame that includes an upper lifting member that enables the frame to be lifted with a crane or other lifting device. First and second hydraulically powered jaws are each attached to the frame. Jaw pivots are provided on the frame, each jaw pivotally attached to the frame at a jaw pivot. First and second hydraulic cylinders are each connected to the frame. Each cylinder pivots on the frame above the jaw pivots, each cylinder connected to the frame at an upper cylinder pivot. Lower cylinder pivots are provided on the jaws, each cylinder pivotally attached to a jaw at a lower cylinder pivot. Each jaw has a concave surface. First and second digging implements are attached to the jaws, the first digging implement attached to the first jaw, the second digging implement attached to the second jaw. Each digging implement has a concave portion. Each digging implement is wider than the jaw to which it is attached so that each implement extends laterally away from the jaw to which it is attached. A pair of side panels is attached to each digging implement at positions spaced away from the jaws.
A method of evacuating hydrocarbons from a plurality of nested tubulars of a well pipe, extending from an underwater well tree, includes attaching a fluid transmission line to the underwater well tree, the fluid transmission line having one end portion forming the attachment to the tree and the other end portion attached to a pump that forces fluid under pressure to the tree and attached nested tubulars. Openings are formed through one or more tubulars at a selected location. A specially configured fitting is attached to the tubulars. The fitting seals the openings. The fitting has an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, pulling a tapered mandrel against the seal. The saddle surrounds the mandrel and bears against an outer tubular of the nested tubulars. The fitting mandrel has a bore through which hydrocarbons escape from the tubulars.

METHOD AND APPARATUS FOR EVACUATING HYDROCARBONS FROM A DISTRESSED WELL
A method of evacuating hydrocarbons from a plurality of nested tubulars of a well pipe that extends from an underwater well tree includes an initial step of attaching a fluid transmission line to the underwater well tree, the fluid transmission line having one end portion forming the attachment to the tree and the other end portion attached to a pump that forces fluid under pressure to the tree and attached nested tubulars. Openings are formed through one or more tubulars of the nested tubulars at a selected location. A specially configured fitting is attached to the tubulars. The fitting seals the openings. The fitting has an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, pulling a tapered mandrel against the seal. The saddle surrounds the mandrel and bears against an outer tubular of the nested tubulars. The fitting mandrel has a bore. Hydrocarbons escape from the tubulars via the mandrel bore.
An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured tool body assembly hav-ing valving members (e.g., safety or kelly values) and valving members holding plugs, balls, or darts to be dropped. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator in-dicates to a user or operator that a ball or plug has passed a selected one of the valving members. A transmitter (or transceiver) provides an ability to generate a wireless signal that is received by receivers (or transceivers) on the tool body assembly. Each receiver (or transceiver) controls an electrical actuator that engages a valving member or the indicator. Wireless signals can be used to open or close a valve or to reset a "tripped" indicator.
