    Abstract: 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.

    Abstract: A sand control screen assembly for use in a wellbore includes a tubular base pipe having a first perforated section. The first perforated section has at least a first opening that allows fluid flow therethrough. The assembly also includes an internal seal element disposed within an internal diameter of the tubular base pipe and positioned at least partially overlapping the first perforated section.

    Abstract: 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. 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.

    Abstract: Inflow control devices for sand control screens. A well screen includes a filter portion and at least two flow restrictors configured in series, so that fluid which flows through the filter portion must flow through each of the flow restrictors. At least two tubular flow restrictors may be configured in series, with the flow restrictors being positioned so that fluid which flows through the filter portion must reverse direction twice to flow between the flow restrictors. A method of installing a well screen includes the step of accessing a flow restrictor by removing a portion of an inflow control device of the screen.

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.

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.

    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).
