Abstract: A seal assembly (60) for controlling the flow of fluids in an annulus (68) between a continuous tubular (62) and a cased wellbore (64) is disclosed. The seal assembly (60) includes anchor slips (72) and a seal element (78). The seal assembly (60) is actuated by communicating hydraulic fluid to a setting assembly (82) via an operating fluid conduit integral with the tubular (62). Upon actuation, the setting assembly (82) axially shifts a pair of slip ramps (74, 76) which radially expands the anchor slips (72) into gripping engagement with the wellbore (64) and radially expands the seal element (78) into sealing engagement with the wellbore (64).

Abstract: An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular (112), which forms a first annulus with the wellbore, and an sand control screen (118) disposed within the outer tubular (112) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway (146) and an axially extending slurry passageway (144), which is defined between a sheet member (140) positioned on the sand control screen (118) and a channel (132). The outer tubular (112) has outlets (116) that are substantially aligned with outlets (142) of the channel (132). When a fluid slurry containing gravel is injected through the slurry passageway (144), the fluid slurry exits through the outlets (116, 142) leaving gravel in the first annulus, thereby gravel packing the interval.

Abstract: A communication tool (100) for communicating hydraulic fluid through a tubing retrievable safety valve (50) is disclosed. The tool (100) has a first section (102) and a second section (132) that are initially coupled together. A set of axial locating keys (112) is operably attached to the first section (102) and is engagably positionable within a profile (62).

Abstract: A sand control screen assembly (40) and method for treating multiple formations traversed by a wellbore (34) in a single trip are disclosed. The sand control screen assembly (40) includes a base pipe (56) with multiple openings (58) that allow fluid flow therethrough. A filter medium (62) is positioned about the exterior of the base pipe (56) to filter particulate matter out of the production fluids. One-way valves (70) are positioned within the openings (58) of the base pipe (56) to prevent fluid flow from the interior of the base pipe (56) to the exterior of the base pipe (56) during and following a treatment process. The one-way valves (70), however, are actuatable to allow fluid flow from the exterior of the base pipe (56) to the interior of the base pipe (56) to allow production of fluids from the formation (14).

Abstract: A transition member (130) coupled between first and second slurry delivery devices (132, 134) for maintaining fluid slurry velocity therethrough is disclosed. Each slurry delivery device (132, 134) has a slurry passageway (144, 164) having a cross sectional area. The transition member (130) includes a transition passageway (200) operable to provide fluid communication between the slurry passageways (144, 164) of the slurry delivery devices (132, 134). The cross sectional area of at least a portion of the transition passageway (200) approximates the cross sectional area of the slurry passageways (144, 164) of the slurry delivery devices (132, 134). This allows the transition member (130) to maintain the fluid slurry velocity above the settling velocity of the slurry.

Abstract: An apparatus (60) for absorbing a shock comprises a first tubular member (62) and a second tubular member (80) that are slidable positioned relative to one another. A plurality of layers (94-104) of energy absorbing members (88) extend radially from the second tubular member (80) such that movement of the second tubular member (80) in a first direction relative to the first tubular member (62) sequentially deforms the layers (94-104) of energy absorbing members (88). As the layers (94-104) are sequentially deformed, a subsequent layer (96) of energy absorbing members (88) begins to deform before the previous layer (94) of energy absorbing members (88) is completely deformed. The deformation of the energy absorbing members (88) absorbs the shock.

Abstract: An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular (110), which forms a first annulus with the wellbore, and an inner tubular (114) disposed within the outer tubular (110) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway (190) and an axially extending slurry passageway (194), which is defined between a channel (170) and the inner tubular (114). The outer tubular (110) has outlets (128) that are substantially aligned with outlets (178) of the channel (170). The portions of both the outer and inner tubulars (110, 114) adjacent the production pathway (190) have openings (122, 146). When a fluid slurry containing gravel is injected through the slurry passageway (194), the fluid slurry exits through the outlets (178, 128) leaving gravel in the first annulus, thereby gravel packing the interval.

In addition, the collet member (64) has a second operating position wherein the collet member (64) applies an axial force on a slip assembly (80) to set the slip assembly (80).
