摘要： 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.

摘要： 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.

摘要： A fluid loss device including a flapper and seat assembly that provide a seal on a lower flapper surface when the flapper is closed and resists pressure in either direction. The flapper and seat assembly is spring biased to contact a flapper support above the flapper to resist deformation of the flapper due to a pressure differential from below the flapper. The flapper and seat assembly may be moved by tubing pressure to release an opening prop that opens the flapper. The valve seat may include an elastomeric seal element to improve the fluid flow restriction. The flapper and seat assembly is also biased upward by a pressure differential from below to above the flapper, to thereby increase the flapper to valve seat pressure as the fluid pressure differential increases.

摘要： A gravel packing apparatus comprises multiple joints each having substantially the same construction and each having a perforated outer tubular (150, 152) positioned around a sand control screen (154, 156) including a slurry passageway (190, 194) and a production pathway (188, 192) therebetween. First and second transition members (210, 204) are disposed at opposite ends of each joint. When two such joints are connected together, the second transition member (204) of one joint is proximate the first transition member (210) of the next joint such that a fluid traveling from the slurry passageway (190) of one joint to the slurry passageway (194) of the next joint travels from the exterior to the interior of the second transition member (204) of the one joint and from the interior to the exterior of the first transition member (210) of the next joint.
