    Abstract: A method for drill pipe tallying includes detecting that a drill bit (14) has tripped in through a rig floor and monitoring movement of a drawworks (6) that supports the drill bit and a length of drill pipe. If a tag interrogating device does not detect a wireless tag (26) associated with a set of slips, the method includes counting the movement of the drawworks toward a drill pipe tally. If a tag interrogating device detects a wireless tag associated with a set of slips, the method includes not counting the movement of the drawworks toward the drill pipe tally. The tag interrogating device is positioned at a fixed location relative to the rig floor.

  • Patent number: 8955603
    Abstract: A system of couplings and method of use of the couplings to locate a downhole tool connected to coiled tubing, such as a bottom hole assembly, within a selected segment of a casing string. The selected segment of casing may be a ported collar or ported housing that permits the treatment and/or stimulation of the adjacent well formation. The system of couplings may be two, three, or four couplings spaced apart at predetermined lengths. The predetermined lengths may be shorter than typical lengths of casing segments. The distance between the first and second coupling may be substantially identical to the distance between the third and fourth coupling. The use of distances between the couplings that are shorter than the length of conventional casing segments may provide surface indicators as to the location of the bottom hole assembly with a higher confidence than relying on a traditional tally sheet.

  • Patent number: 8020614
    Abstract: A method and apparatus for the decomposition of hydrogen peroxide, particularly for use as a hydrocarbon well bore and pipeline cleaning and maintenance aid. The apparatus includes a decomposition engine having an inlet manifold extending centrally within the housing and having means for passage of hydrogen peroxide through the manifold wall through a catalyst stack. The decomposition products produced are directed through an exit venturi. The decomposition products are passed through a piping system which allow the selective venting or introduction of the products into a facility to be cleared. Control means are coupled to the engine and valving to allow for the selective adjustment of temperature and or pressure of the decomposition products, as well as the introduction and diversion of the blend into the facility.

  • Patent number: 7963328
    Abstract: A process and system for release and recovery of methane from subterranean methane hydrate deposits in which heated CO2 is used to displace methane from the methane hydrate deposits and a portion of the displaced methane is routed to a combustion device proximate the deposit for combustion in-situ, generating heated CO2 which is introduced into the deposit, displacing additional methane, a portion of which is routed to the combustion device, thereby providing a substantially self-sustaining process. Portions of the displace methane not routed to the combustion device are captured for use elsewhere.

  • Publication number: 20110030947
    Abstract: The present disclosure is directed to a system and method for stimulating subterranean zones. In some implementations, a method for stimulating a subterranean zone includes pumping stimulation fluid through a tubing string in a wellbore during a stimulation process. The tubing string includes a plurality of sleeves with each associated with a different treatment zone of the subterranean zone. A time for each of a plurality of different sealers entering the tubing string is detected. Each of the plurality of different sealers is associated with a different one of the plurality of sleeves. A location of the plurality of different sealers in the tubing string is substantially determined based, at least in part, on the associated entry time.

  • Patent number: 7762327
    Abstract: A casing annulus is remediated by inserting a hose into a casing annulus, the hose having a nozzle on its lower end. An acoustic signal is directed into the annulus. A sensor in the hose receives the acoustic signal and transmits data from the sensor to the surface. The data represents the acoustic signal arrival time to the sensor, and an analyzer estimates the sensor depth based on the data. The hose is inserted from a reel into a wellhead above the annulus. An electrical transducer mechanically coupled to the hose creates the acoustic signal. The signal is propagated along the hose and transferred to the fluid in the annulus, where it then propagates further into the annulus. The transducer can be installed on a hose roller along which the hose is fed into the wellhead.

  • Publication number: 20100116492
    Abstract: Methods and devices are provided for accurately determining depths of certain structures in downhole strings. Locator tools comprise a shaft and a plurality of locator springs longitudinally mounted on the shaft. The locator springs are biased to expand and are configured to compress to allow the tool to traverse past restrictions in the downhole string. Each locator spring includes a locating pad that allows it to engage with an internal locating notch in the downhole string. The internal locating notch is sized to mate with the locator tool, i.e., to allow the locator springs to engage the internal locating notch. In this way, the depth of internal locating notches may be determined precisely and accurately by sensing engagement of the tool with the internal locating notch. Advantages of certain embodiments include more accurate depth determination, repeatable engagements of the tool, and reduced false engagements.
