  • Patent number: 10329472
    Abstract: Fluid additives suitable for use in a wellbore (e.g., a liquid comprising an aqueous miscible fluid, a liquid surfactant, or both) may be converted into a liquid-infiltrated porous silica that is a flowable bulk solid. The flowable bulk solid may then be handled and stored as a traditional solid wellbore additive. For example, the flowable bulk solid may be added to an aqueous fluid to produce a wellbore fluid that is then introduced into a wellbore penetrating a subterranean formation.

  • Patent number: 10280707
    Abstract: A re-closable toe sleeve is disclosed where the toe sleeve has a port allowing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. A burst disk is placed inside the port to prevent fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. However upon the fluid in the interior of the toe sleeve reaching a predetermined level the burst disk is removed or otherwise modified to allow fluid access through the port. A sliding sleeve is placed within the toe sleeve so that the sliding sleeve can be moved to cover the port thereby preventing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve or the sliding sleeve may be moved to uncover the port thereby allowing fluid access from the interior of the toe sleeve to the exterior the toe sleeve. The sliding sleeve is mechanically moved from the surface and is typically run into the well in the open position such that the port is uncovered by the sliding sleeve.

  • Patent number: 9816350
    Abstract: A ported sub is operated with a pressure actuated shifting sleeve. A first rupture disc is set at a lower pressure than the test pressure for the tubing string that houses the ported sub. The first rupture disc breaks at a lower pressure than the string test pressure to expose well fluids to a disintegrating plug. The plug slowly disintegrates to then expose tubing pressure to a chamber and a second rupture disc with the chamber configured to have no effect on moving the sliding sleeve. When the tubing pressure is then raised to a predetermined pressure below the test pressure for the string, the second disc breaks exposing a piston to tubing pressure on one side and trapped low pressure being the opposite side of the string. The differential moves the sleeve to open a port to let tools be pumped into position without a need to perforate.

    Abstract: A shifting sleeve has differential piston areas so that applied pressure displaces the sleeve against spring bias, which preferably is a series of Belleville washer stacks associated with modular mandrel components, to obtain the desired opposing force to the movement initiated with pressure applied to differential piston areas. An indexing feature is located between the sleeve and the mandrel passage wall and on a predetermined number of cycles disables the Belleville washer stacks from biasing the sleeve in an opposed direction as when pressure is applied. At this time the pressure in the mandrel acting on the differential piston area simply shifts the sleeve to open a lateral port so that fracturing through the cement that was earlier placed with the port closed can take place.

  • Patent number: 9212534
    Abstract: Disclosed herein are cement compositions and methods of using set-delayed cement compositions in subterranean formations. In one embodiment a method of plugging a wellbore is described. The method comprises providing a set-delayed cement composition comprising pumice, hydrated lime, a cement set retarder, and water; activating the set-delayed cement composition to produce an activated set-delayed cement composition; introducing the activated set-delayed cement composition into the wellbore; and allowing the activated set-delayed cement composition to form a plug in the wellbore that has a permeability of less than 0.1 millidarcy.

  • Patent number: 9103189
    Abstract: Disclosed herein is a segmented seat for use in wellbore servicing systems, comprising an annular-shaped seat with an upward facing surface for receiving an obturator, the seat defining a central passageway. The seat comprises one or more slots or passageways and, wherein at least one slot or passageway extends continuously between seat segments. The at least one slot or passageway contains a nonmetallic material suitable for retaining the segments together yet frangible or flexible enough to allow the segments to separate when forced to do so. The segments have gripping surfaces which prevent or inhibit rotation of the seat during removal.

  • Patent number: 9103197
    Abstract: The switching device comprises an electronic switch (111) embedded within a downhole tool (100) and an activator (20) for remote switching of the electronic switch (111). The activator (20) may be a handheld unit that is used at the surface of the wellbore by an operator or may be a wireline run unit. The activator (20) permits wireless and contactless activation of the electronic switch (111) without the need for mechanical switches which could provide a point of failure for the downhole tool (100). The electronic switch (111) comprises an electronics module and a power source such as one or more batteries (126) wherein in the active configuration, the switch (111) can allow electrical connection between the electronics module and the power source (126) and in the inactive configuration, the switch (111) prevents electrical connection between the electronics module and the power source (126).

  • Patent number: 9090815
    Abstract: Asparaginase, such as asparaginase derived from Aspergillus oryzae, may be used to break down or defragment polyacrylamides in oil field applications. The asparaginase is useful in reducing the viscosity of a fracturing fluid containing polyacrylamide and a crosslinking agent. The asparaginase is also useful in breaking down or defragmenting a polyacrylamide friction reducing agent, such as in a slickwater fracturing operation. Asparaginase may also be used to break down or defragment filter cakes containing polyacrylamide.

  • Patent number: 8997850
    Abstract: 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 having 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 indicates 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.

  • Patent number: 8939209
    Abstract: 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. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members.
