Abstract: A perforating apparatus (100) includes a plurality of shaped charges (102) each having an initiation end and a discharge end. A detonating cord (116) is operably coupled to the initiation ends of the shaped charges (102). A carrier (106) contains the shaped charges (102). The carrier (106) includes at least one discharge location corresponding to the discharge ends of the shaped charges (102) when the perforating apparatus (100) is in its operable position. The discharge location has first and second material layers (122, 124) wherein the second material layer (124) exhibits resilient recovery such that an opening created by a jet formed from detonating one of the shaped charges (102) in the second material layer (124) is smaller than an opening created by the jet in the first material layer (122), thereby retaining debris in the perforating apparatus (100) with the second material layer (124).

Abstract: A submersible pump assembly (100) for removing a production inhibiting fluid (102) from a well (110) and method for use of the same is disclosed. The submersible pump assembly (100) includes a composite coiled tubing (120) and a submersible pump (112) coupled to the tubing (120) that is disposed within a fluid accumulation zone (104) of the well (110). The tubing (120) defines a fluid communication path substantially from the fluid accumulation zone (104) to the surface. The submersible pump (112) includes a port (114) for intaking production inhibiting fluid (102). The tubing (120) includes a composite layer in which energy conductors are integrally positioned. The energy conductors provide power to the submersible pump (112) such that the production inhibiting fluid (102) may be pumped from the fluid accumulation zone (104) to the surface via the fluid communication path of the tubing (120).

Abstract: A sand control completion (100) for installation in a wellbore (102) includes first and second packers (114, 116) that define a first zone (110) in the wellbore (102). A production tubing (120) extends substantially through the first zone (110). Positioned between the first and second packers (114, 116) are a sand control screen (130), an inflow control valve (122) and a crossover valve (126). The sand control screen forms a first annulus (152) with the production tubing (120) and a second annulus with the wellbore (102). The inflow control valve (122) is operable to selectively allow and prevent fluid communication between the first annulus (152) and the interior of the production tubing (120). The crossover valve (126) is operable to selectively allow and prevent fluid communication between the production tubing (120) and the second annulus.

Abstract: A system and method of pushing user-selected data items from a host system to a user's mobile data communication device upon detecting the occurrence of one or more user-defined event triggers is provided. The user may then move (or file) the data items to a particular folder within a folder hierarchy stored in the mobile data communication device, or may execute some other system operation on the data item. Software operating at the mobile device and the host system then synchronizes the folder hierarchy of the mobile device with a folder hierarchy of the host system, and any actions executed on the data items at the mobile device are then automatically replicated on the same data items stored at the host system, thus eliminating the need for the user to manually replicate actions at the host system that have been executed at the mobile data communication device.

Abstract: A communication tool (100) includes a housing (102) having recesses (110) and a set of axial locating elements (112) radially extendable through the recesses (110) and engagably positionable within a profile of a tubing retrievable safety valve (50). An anti rotation device (140) is radially outwardly extendable relative to the housing (112). The anti rotation device (140) operably engages the tubing retrievable safety valve (50) to substantially prevent relative rotation between at least a portion of the communication tool (100) and the tubing retrievable safety valve (50). A cutting tool (148) is radially outwardly extendable relative to the housing (102). The cutting tool (148) is operable to create a fluid passageway (150) between a non annular hydraulic chamber (60) and an interior the tubing retrievable safety valve (50).

Abstract: An apparatus (110) and method for treating an interval of a wellbore comprises an outer tubular (112) disposed within the wellbore. A sand control screen (118) is disposed within the outer tubular (112). A treatment fluid passageway (144) is formed between the sand control screen (118) and outer tubular (112). In addition, a production pathway (130) is formed between the sand control screen (118) and outer tubular (112). When the apparatus (110) is in an operable position, the region between the outer tubular (112) and the wellbore serves as a primary path for delivery of a treatment fluid, the production pathway (130) serves as a secondary path for delivery of the treatment fluid if the primary path becomes blocked and the treatment fluid passageway (144) serves as a tertiary path for delivery of the treatment fluid if the primary and secondary paths become blocked.

A sleeve (114) is slidably positioned within the housing (80) and has a first position wherein fluid communication through the openings (112) is prevented and a second position wherein fluid communication through the openings (112) is allowed. A combustible element (124) is positioned in the combustion chamber (98) such that combusting the combustible element (124) generates pressure in the combustion chamber (98) that actuates the sleeve (114) from the first position to the second position.

Thereafter, the drill string (52) is disconnected from the drill bit (30) for retrieval to the surface leaving the completion assembly (50) and the drill bit (30) downhole.
