    Abstract: A coiled adaptive seat is held to a smaller diameter for delivery with a tool that can feature a locating lug for desired alignment of the seat with an intended groove in the inner wall of a tubular. The release tool retracts a cover from the seat allowing its diameter to increase as it enters a groove. Alternatively the adaptive seat is released near the groove and pushed axially in the string to the groove for fixation. Once in the groove the inside diameter of the string is a support for a blocking object so that sequential treatment of parts of a zone can be accomplished. The blocking object is removed with pressure, dissolving, milling or disintegration leaving a narrow ledge in the tubular bore from the seat that can simply be left in place or milled as well. An E4#10 from Baker Hughes is modified for adaptive seat delivery.

  • Patent number: 9550247
    Abstract: A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket defines a pocket in a first surface and a groove in a second, opposing surface thereof. The disc-shaped coupon is seated in the pocket and the wire is seated in the groove with the electrical junction therebetween aligned with an aperture connecting the pocket to the groove. A sealing material is used to form a watertight seal between the disc-shaped coupon and the pocket and fills the groove. The device includes a hydrophilic porous member having a first surface in communication with the conductive media and a second surface in communication with an external environment.

  • Patent number: 9255456
    Abstract: A method and apparatus for improving the efficiency of a drill string that includes drilling pipe, a dump valve, a positive displacement motor and a rotary drill bit driven by the motor utilize a dump valve that does not depend upon a pressure loss to maintain the dump valve in a position which closes communication between the drilling string and the annulus between the drilling string and the well bore or casing. The dump valve includes a flow sleeve that is axially moved to close outlet passages to the annulus by the flow of fluid through the outlet passages rather than a pressure drop across the flow sleeve.

  • Publication number: 20150041121
    Abstract: A localized inflow tracer (112) may be flushed from a gravel pack (104) surrounding a base pipe (102) of a production well by outwardly venting the inflow tracer. The base pipe (102) may include a non-perforated section (106) disposed adjacent to one or more perforated sections (108). A tracer carrier (110) may be disposed circumferentially about at least a portion of the non-perforated section (106) of the base pipe (102). An inflow tracer (112) may be released from the tracer carrier (110) into production fluid within the gravel pack (104) proximate to the non-perforated section (106) of the base pipe (102) such that the inflow tracer is flushed from the gravel pack (104) into individual ones of the one or more perforated sections (108) of the base pipe (102) and transported with the production fluid. The inflow tracer (112) may be prevented from being flushed directly from the tracer carrier (110) into the base pipe (102) due to a lack of permeability of the non-perforated section of the base pipe (102).
