Abstract: A bi-directional valve with valve elements having compliant features biasing them together to maintain a sealing interface that defines a fluid communication barrier within the valve. Parting the valve elements from one another removes the sealing interface to allow fluid communication across the valve elements. The valve includes a side port and a choke member that selectively blocks fluid flow through the valve when moved adjacent the side port and selectively opens the valve to fluid communication when moved away from the side port. The choke member remains adjacent the side port until the valve elements are spaced a distance apart greater than that at which valve erosion or fluid cavitation occurs.

Abstract: An improved process for catalytic reformers and their use for the catalytic reforming of petroleum naphthas. More particularly, the invention relates to an improved reformer unit which can be operated at higher throughput relative to compressor size. The invention utilizes pressure swing adsorption to improve the hydrogen content of hydrogen containing streams generated by and utilized in catalytic reforming processes. The invention also has the capability of enabling compressor-limited catalytic reforming units to be operated at increased capacities.

Abstract: A hydraulic connection mechanism for use in a wellbore comprises an upper connection tool, a lower connection tool configured to engage the upper connection tool and form a fluid communication pathway through the hydraulic connection mechanism, and a debris barrier disposed in the fluid communication pathway. The debris barrier comprises a body element, and a spring element configured to maintain the body element in a closed position when the upper connection tool is disengaged from the lower connection tool.

Abstract: An anchor for a wellbore is adaptable to be operated in at least two separate and distinct ways. In one embodiment, a whipstock anchor is provided that can be operated either mechanically or hydraulically. In another embodiment, the anchor is designed to run through a restriction in a retracted position and thereafter expanded to position a wellbore tool in the wellbore. Preferably, the anchor is expandable to set in wellbores of various sizes and either cased or uncased.

Abstract: The present invention generally relates to an apparatus and method for use in a wellbore. In one aspect, a downhole tool for use in a wellbore is provided. The downhole tool includes a housing having a shaped inner bore, a first end and a second end. The downhole tool further includes a rotor having a plurality of extendable members, wherein the rotor is disposable in the shaped inner bore to form at least one chamber therebetween. Furthermore, the downhole tool includes a substantially axial fluid pathway through the chamber, wherein the fluid pathway includes at least one inlet proximate the first end and at least one outlet proximate the second end. In another aspect a downhole motor for use in a wellbore is provided. In yet another aspect, a method of rotating a downhole tool is provided.

Abstract: The present invention generally relates to a disconnect for use in a wellbore to separate a tubular string from a stuck wellbore component. In one aspect, the invention includes a disconnect with a first portion and a second portion and a lock nut preventing the separation of the two portions. When a predetermined fluid force is applied to a piston in the disconnect, a tensile sleeve fails and the first and second portions of the disconnect separate, thereby leaving a portion of the disconnect in the wellbore with the stuck component. In one embodiment, the tensile sleeve's failure permits an annular piston to dislodge a wedge sleeve from the lock nut, thereby permitting separation of the first and second portion of the disconnect.

Abstract: A fixed-bed catalytic reformer unit is converted to moving bed reactor/cyclic regenerator operation by re-using the fixed bed reactors of the original unit as regenerator vessels operated in cyclic regeneration mode in a new catalyst regeneration section. A flow connection, suitably a liftpipe, is provided to convey spent catalyst from the spent catalyst outlet of a new moving bed reactor section to the converted regenerator section, together with a flow connection for regenerated catalyst from the regenerator section to the regenerated catalyst inlet of the new moving bed reactor section. A flow control distributor directs spent catalyst sequentially to each of the regenerator vessels to carry out the regeneration with regeneration gas. Each regenerator vessel is cycled through a fill, regeneration, discharge sequence to maintain a continuous flow of catalyst to and from the reactor section.
