  • Patent number: 8720561
    Abstract: A downhole tool provided within a casing string for use in cement staging operations. The tool includes a sleeve in the tool that selectively slides downward under pressure to expose ports formed in a side wall of the tool. Also, an annulus through the tool is selectively blocked so that cement in the casing string flows radially outward through the ports and into an annulus between the tool and a wellbore. An inflatable packer is included that is integral to the body of the tool and is inflated with a fluid that is pushed into the packer as the sleeve slides downward. An optional expanding agent can be included in the packer that is a metal oxide and is activated with the addition of water.

  • Patent number: 8695717
    Abstract: Conventional formation evaluation with dual inflatable packers includes the steps of pressurizing the packers so as to isolate an annular portion of the borehole wall, collecting one or more samples of formation fluid via the isolated portion of the borehole wall, and depressurizing the packers so as to permit movement of the mandrel within the borehole. A sampling method and apparatus that utilize one or more of the following to advantage is provided: restricting deformation of the packers during inflation using an annular bracing assembly; actively retracting the packers using ambient borehole pressure; and substantially centralizing the mandrel intermediate the packers so as to resist buckling of the mandrel.

  • Publication number: 20140096979
    Abstract: A packer assembly with an enhanced sealing layer is provided. The packer assembly may have an outer bladder with drains. The packer assembly may further have an inflatable inner packer disposed inside the outer bladder such that inflation of the inner packer causes the outer bladder to expand. End pieces may be coupled to the inner bladder and the outer bladder, and flowlines may be in fluid communication with the drains and the end pieces. A piston ring may reinforce the packer assembly. The piston ring may have three or more passive pistons which expand with the packer assembly during testing.

  • Patent number: 8657004
    Abstract: A downhole tool provided within a casing string for use in cement staging operations. The tool includes an inflatable packer that is integral to the body of the tool and ports in sides of the tool. The ports are selectively opened and closed for circulating cement from within the tool so that cement can flow between the casing string and a wellbore. The ports are actuated by sliding the casing string upward or downward within the wellbore. The packer can be pressure tested after being set to ensure its efficacy.

  • Publication number: 20140020912
    Abstract: An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.

  • Patent number: 8501012
    Abstract: A filter sub apparatus comprising a housing configured to contain a filter and a bypass mechanism is provided. The bypass mechanism may be actuated upon debris buildup on the filter resulting in a load applied to the bypass mechanism rising above a predetermined lower level. A method to prevent chemical injection process failures may also be provided. The method may comprise the steps of providing a filter sub prior to a check valve. The filter sub may include a filter and a bypass mechanism. Another step may be passing fluid through the filter. In addition, the steps may also include containing at least some debris on a side of the filter such that the debris is prevented from reaching the check valve. A further step may be actuating the bypass mechanism after the debris builds up to a level in which a resulting load applied to the bypass mechanism exceeds a lower limit.
