    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).

    摘要: An apparatus and method for gravel packing an interval of a wellbore is disclosed. The apparatus comprises an outer tubular (110) forming a first annulus with the wellbore and an inner tubular (114) disposed within the outer tubular (110) forming a second annulus therebetween. The second annulus includes an axially extending slurry passageway (194) and an axially extending production pathway (190). The portion of the outer tubular (110) adjacent the slurry passageway (194) has an outlet (128). The portion of both the outer and inner tubulars (110, 114) adjacent the production pathway (190) has a plurality of openings (122, 146). The slurry passageway (194) is in fluid isolation from the production pathway (190) such that when a fluid slurry containing gravel is injected through the slurry passageway (194), the fluid slurry exits through the outlet (128) leaving gravel in the first annulus, thereby gravel packing the interval.

    摘要: 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.

    摘要: In general, a method is provided for completing a subterranean wellbore, and an apparatus for using the method. The method comprises positioning an expandable sand-control device in the wellbore thereby forming an annulus between the sand-control device and the wellbore; depositing a filter media in the annulus; and after the depositing step, radially expanding the sand-control device to decrease the volume of the annulus. The sand-control device can be a sand screen or slotted or perforated liner having radially extending passageways in the walls thereof, the passageways designed to substantially prevent movement of the particulate material through the passageways and into the sand-control device. Where a slotted liner is desired, the passageways can be plugged during positioning and later unplugged for production. Another embodiment of the method and apparatus presented herein comprises positioning a well-completion device into the wellbore, thereby forming an annulus between the well-completion device and the wellbore, the well-completion device having a flexible, permeable membrane sleeve surrounding an expandable sand-control device; and thereafter radially expanding the sand-control device to decrease the volume of the annulus, thereby also expanding the membrane sleeve. The well-completion device can further include a layer of filter media encased between the membrane sleeve and the sand-control device. The filter media may be of any type known in the industry. Preferably, the membrane sleeve, when expanded, substantially fills the annular space extending between the wellbore and the sand-control device by deforming to substantially contour the wellbore.

Where a slotted liner is desired, the passageways can be plugged during positioning and later unplugged for production. The filter media is typically a particulate material and can be deposited as a slurry comprising liquid material and particulate material, or as a cement slurry. The step of expanding the sand-control device further includes squeezing at least a portion of the liquid of the slurry through the sand-control device passageways thereby forming a pack in the wellbore annulus. The liquid material can be water-based, oil-based or emulsified and can include gelling agents. Further, the particulate can be resin coated with a delayed activation of the resin. The filter media can also be a foam system. The foam can also include decomposable material which can be decomposed after placement of the foam in the annulus.

    摘要: A sand control screen assembly (200) positionable within a production interval of a wellbore that traverses a subterranean hydrocarbon bearing formation comprises a base pipe (202) having openings (204) in a sidewall section thereof that allow fluid flow therethrough. A filter medium (210) is positioned about the exterior of at least a portion of the base pipe (202). The filter medium (210) selectively allows fluid flow therethrough but prevents the flow of particulate of a predetermined size therethrough. A seal member (218, 220, 222) is operably associated with the base pipe (202). The seal member (218, 220, 222) has a one-way valve configuration and a valve open configuration such that the seal member (218, 220, 222) controls fluid flow through the openings (204) of the base pipe (202).

    摘要: A sand control screen assembly (40) and method for treating formations traversed by a wellbore (34) in a single trip are disclosed. The sand control screen assembly (40) includes a base pipe (56) with a plurality of 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 operably associated 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 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).
