Abstract:
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).
Abstract:
An apparatus (60) and method for treating an interval of a wellbore comprises an outer tubular (62) disposed within the wellbore. A sand control screen (92) is disposed within the outer tubular (62). A slurry passageway (88) is formed between the sand control screen (92) and outer tubular (62). In addition, a production pathway (90) is formed between the sand control screen (92) and outer tubular (62). When the apparatus (60) is in an operable position, the region between the outer tubular (62) and the wellbore serves as a primary path for delivery of a fluid slurry, the production pathway (90) serves as a secondary path for delivery of the fluid slurry if the primary path becomes blocked and the slurry passageway (88) serves as a tertiary path for delivery of the fluid slurry if the primary and secondary paths become blocked.
Abstract:
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).
Abstract:
A flow control apparatus (100) for controlling the inflow of production fluids (134, 140) from a subterranean well includes a tubular member (118) having at least one opening (138) that allows fluid flow between an exterior of the tubular member (118) and an interior flow path of the tubular member (118) and a flow restricting device (120) operably positioned in a fluid flow path between a fluid source and the at least one opening (138). The flow restricting device (120) includes a valve (128, 130) and an actuator (126). The actuator (126) includes a material that swells in response to contact with an undesired fluid (140), such as water or gas. The flow restricting device (120) is operable to autonomously reduce the fluid flow through the flow control apparatus (100) in response to contact between the material and the undesired fluid (140).
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:
An apparatus for gravel packing a production interval (42) of a wellbore (32) comprises first and second sand control screen assemblies (56, 58) connected downhole of a packer assembly (46) and a cross-over assembly (40) that provides a communication path (74) downhole of the packer assembly (46) for a gravel packing fluid and a communication path (92) uphole of the packer assembly (46) for return fluids. A wash pipe assembly (66) extends into the first and second sand control screen assemblies (56, 58) forming an annulus (84) therebetween. A valve (70) is positioned within the wash pipe assembly (66) in a location between the first and second sand control screen assemblies (56, 58). The valve (70) is actuatable from a closed position to an open position when the beta wave (100) is proximate the location of the valve (70).
Abstract:
An apparatus (60) and method for gravel packing an interval of a wellbore is disclosed. The apparatus (60) comprises a sand control screen (78) positioned within the wellbore and a tubular member (62) disposed within the wellbore forming a first annulus with the sand control screen (78) and a second annulus with the wellbore. The tubular member (62) has an axially extending production section (64) with a plurality of openings (66) and an axially extending nonproduction section (68) with a plurality of outlets (70). A channel (72) is disposed within the first annulus such that the channel (72) is substantially circumferentially aligned with the nonproduction section (68) of the tubular member (62) forming a slurry passageway (74) therewith.
Abstract:
A multi-zone packing system having unique features that allow for remote operation, thereby eliminating the need to raise and lower a work string and crossover tool to various zones of interest during a frac pack, gravel pack or related completion procedure. The squeeze pack system has a crossover tool or port collocated with each zone of interest and remotely operated closing devices to allow for the setting of each packer and the packing job to be performed with minimal or no movement of the work string.
Abstract:
A gravel packing screen with an inflow control device and a bypass. A well screen includes a flow restricting device for restricting inward flow through the screen, and a bypass device for increasing a proportion of the inward flow which passes through the flow restricting device, the bypass device including a material which swells in response to contact between the material and fluid in a well. A method of gravel packing a well includes installing a screen in the well, the screen including a flow restricting device which restricts flow through the screen, and a bypass device for selectively permitting relatively unrestricted flow through the screen; and actuating the bypass device in response to contact between a material of the bypass device and fluid in the well, thereby increasingly restricting flow through the screen. Flow through the flow restricting device and flow through the bypass device may be in parallel.
Abstract:
A screen assembly (60) comprises a base pipe (62) having perforated and nonperforated sections (66, 68), ribs (70) circumferentially spaced therearound and a filter medium (84) positioned around the ribs (70) having voids (92, 94) therethrough. The screen assembly (60) includes a slurry passageway (98) defined by the nonperforated section (68) of the base pipe (62), two of the ribs (70) and the portion (100) of the filter medium (84) that is circumferentially aligned with the nonperforated section (68). This portion (100) of the filter medium (84) has a filler material (96) disposed within the voids (92, 94) to create a fluid tight seal for a fluid slurry. The fluid slurry is discharged from the screen assembly (60) to a plurality of levels of the interval through exit ports (106) in a plurality of manifolds (102) when the screen assembly (60) is in an operable position.
