A downhole debris recovery tool including a ported sub coupled to a debris sub, a suction tube disposed in the debris sub, at least one magnet disposed in the debris removal tool, and an annular jet pump sub disposed in the ported sub and fluidly connected to the suction tube. A method of removing debris from a wellbore including the steps of lowering a downhole debris removal tool into the wellbore, flowing a fluid through a bore of an annular jet pump sub, jetting the fluid from the annular jet pump sub into a mixing tube, displacing an initially static fluid in the mixing tube through a diffuser, thereby creating a vacuum effect in a suction tube to draw a debris-laden fluid into the tool, flowing the debris-laden fluid past at least one magnet disposed in a debris housing, and removing the tool from the wellbore is also disclosed.

Debris catcher for collecting well debris

A non-metallic element system is provided as part of a downhole tool that can effectively seal or pack-off an annulus under elevated temperatures. The element system can also resist high differential pressures without sacrificing performance or suffering mechanical degradation, and is considerably faster to drill-up than a conventional element system. In one aspect, the composite material comprises an epoxy blend reinforced with glass fibers stacked layer upon layer at about 30 to about 70 degrees. In another aspect, a mandrel is formed of a non-metallic polymeric composite material. A downhole tool, such as a bridge plug, frac-plug, or packer, is also provided. The tool comprises a support ring having one or more wedges, an expansion ring, and a sealing member positioned with the expansion ring.

Non-metallic mandrel and element system

Methods and apparatus for use in a welibore to meter and choke certain components from being produced, based upon their density relative to the density of oil are described herein. The device includes an inner tubular body portion having apertures in the wall thereof for passing oil, an outer tubular body and at least one metering orifice therebetween to meter production. Disposed around the inner body is an axially movable member to selectively cover and expose the apertures of the inner body, thereby permitting fluid to flow therethrough.

Flow control apparatus for use in a wellbore

A non-metallic element system is provided which can effectively seal or pack-off an annulus under elevated temperatures. The element system can also resist high differential pressures without sacrificing performance or suffering mechanical degradation, and is considerably faster to drill-up than a conventional element system. In one aspect, the composite material comprises an epoxy blend reinforced with glass fibers stacked layer upon layer at about 30 to about 70 degrees. A downhole tool, such as a bridge plug, frac-plug, or packer, is also provided. The tool comprises a first and second support ring having one or more tapered wedges, a first and second expansion ring, and a sealing member disposed between the expansion rings and the support rings.

Resin impregnated continuous fiber plug with non-metallic element system

An apparatus and method of controlling the flow of hydrocarbons into and/or out of a string of tubing disposed in a wellbore. In one embodiment, the apparatus comprises a tubular member having at least one aperture formed in a wall thereof and a sleeve disposed radially outward of the tubular member. The sleeve is selectively movable between a first position and a second position to control the flow between the outside and the inside of the tubular member. In one aspect, the apparatus further comprises a biasing member disposed adjacent the sleeve and adapted to apply a force against the sleeve in an axial direction and further comprises a piston adapted to receive a hydraulic pressure to move the sleeve against the force of the biasing member. In another aspect, the apparatus further comprises a electromechanical device adapted to selectively move the sleeve between the first position and the second position and further comprises a control line adapted to conduct an electrical current. In another embodiment, the apparatus comprises a tubular member having at least one aperture formed therein and a fixed ring and a rotatable ring disposed radially outward of the tubular member. In still another embodiment, the apparatus comprises a plurality of annular ribs having an inner surface, at least one support rod disposed along the inner surface of the annular ribs, and at least one control line disposed along the inner surface of the annular ribs.

A connector for providing a pathway between a first screened tubing and a second screened tubing. In one embodiment, the connector includes an annular pipe coupled to the first screened tubing at a first end and coupled to the second screened tubing at a second end. The annular pipe defines a plurality of channels disposed therein. The channels are configured to provide the pathway between the first screened tubing and the second screened tubing.

Screen assembly with flow through connectors

In one aspect of the invention apparatus and methods are provided for completing a wellbore using expandable sand screen. An apparatus including a section of expandable sand screen, and an expanding member is disposed in the wellbore on a tubular run-in string. Thereafter, the expandable sand screen is expanded in a producing area of the wellbore.
