  • Publication number: 20240133263
    Abstract: The packer system includes a packer mandrel, an upper support or gage ring, a seal member, an upper slip device, an upper cone, a lower cone, a lower slip device, a setting sleeve, and a setting piston. The seal member has a run-in position and a set position. The set position seals against a borehole at a location in a borehole. The setting sleeve has a bypass position to transfer load of the setting piston away from the lower slip device and to the lower cone, the seal member, and the upper cone to set the seal member and upper slip device before the lower slip device. The setting sleeve has a released position to separate from the setting piston so that the load of the setting piston can finally be applied on the lower slip device for expansion of the lower slip device at the proper time and location.

  • Patent number: 11814924
    Abstract: The apparatus prepares a downhole tool component, particularly a slip for a plug that seals zones in a wellbore. The apparatus includes a casing holder, a cone insert, and a cap. There is a bottom center connector to hold the cone insert within the casing holder. There are a plurality of spacing bolts, and a top center connector to hold the slip within the space between the cap, the cone insert, and the casing holder. The top center connector can adjust distance between the slip and the cone insert so that the coating on the ramp surface of the slip has a uniform thickness. The invention includes the method of using the apparatus to prepare the slip with coating of uniform thickness to removably engage another component of the apparatus.

  • Patent number: 11512555
    Abstract: The retrievable packer system includes a packer mandrel, a lock ring, an upper cone, a lower cone, a slip device, a retrieval mandrel, and a plurality of push rods. The lock ring is attached to the packer mandrel, followed by the upper cone, the slip device, the lower cone, and the retrieval mandrel. The lower cone has lower cone rod channels, and the push rods anchored on the retrieval mandrel slide through respective channels toward the upper cone. The packer system is run into the borehole with each rod in the first position relative to a tip end of the lower cone and the slip device in the run-in position. The packer system is set and can be locked at a location in the borehole. Each push rod can push the upper cone to return the slip device to the run-in position for retrieval of the packer system.

  • Patent number: 10729802
    Abstract: The present technology relates to composites, apparatuses, systems, and methods that are based on a photocurable composite useful for stabilizing, supporting, or otherwise healing an injured limb. The photocurable composite includes a light-curable resin and a filler material, where the light-curable resin includes about 50 vol % to about 99 vol % (based on the volume of the light-curable resin) of an acrylate-functionalized oligomer, wherein the backbone of the oligomer comprises a polyurethane, a polyether, a polyester, or a combination of any two or more thereof; about 1 vol % to about 50 vol % of a radical-reactive diluent; about 0.001 vol % to about 2 vol % of a photoinitiator; and optionally about 0.05 to about 25 vol % of a surface cure protection agent.

  • Publication number: 20190071949
    Abstract: A downhole system, such as a packer or a bridge plug, isolates zones in a wellbore. Each downhole system includes a mandrel, a sealing member, ring members, and support rings. Each support ring has an extended configuration to position the support ring between the respective ring member and sealing member during deployment and before installation and a collapsed configuration to prevent extrusion of the ring member and sealing member after installation. Ring caps can be added between the support rings and ring members for additional support.

  • Patent number: 9523256
    Abstract: A fold back ring for a swell packer is disclosed. A swell packer has a support member, a swellable element coupled to the support member, and a fold back ring coupled to the support member and engaging the swellable element. The fold back ring is sized and positioned such that when the swellable element swells, the fold back ring flexes outwardly and is caught between the swellable element and the interior surface of the well. The fold back ring therefore forms a barrier against extrusion of the swellable element.

  • Patent number: 8004491
    Abstract: A system/method to store and compare computer generated vector lines through an insecure or a secure communication channel. Using an input device (i.e. computer Keyboard, finger, soft keypad, or any other input from body movements, electrical current, or impulses, or input from human or mechanical sound waves) to a physical machine, or through a token (i.e. credit card, USB token, which can be carried around by user), a user enters and sends their unique identifier and reference code (i.e. PIN, password, other secret code) to the physical machine by making a contact or contact-less to the computer system. As part of the enrollment process the user inscribes a pre-determined set of continuous vector lines (CVLs). The CVLs include data points that are collected from any computer pointing device in a specific format, using a push down anatomical technique and are sent to local active content (i.e. a library, or a program, or an add-on to the internet browser i.e.

  • Publication number: 20020103834
    Abstract: A method of analyzing an electronic text document using a knowledge bank. The knowledge bank is formed of a plurality of lexicons. The analysis is conducted by defining for each of the lexicons an associated subject header and then defining a list of word terms having a logical relationship with the subject header. The document is then analyzed using the plurality of lexicons.
