A multi-zone, one trip completion system for a wellbore is described. A plurality of isolation packers is installed in borehole to isolate a plurality of zones of the annulus between a tubing string and a wellbore. Each tubing string section is positioned in a zone and comprises a selectively openable stimulation port to provide stimulation fluid to its zone and a selectively openable production port to receive fluid from its zone. The system also comprises a circulation system with a plurality of circulation tubes and circulation tube valves, being configurable in a plurality of configurations to selectively connect, via a circulation flow path, the central bore or the borehole annulus of a wellbore at each of the plurality of sections, to an upper circulation flow path open to an annulus above an uppermost of the plurality of isolation packers.

Multi-zone single trip completion system

An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated.

Expandable apparatus and related methods

In one aspect, an apparatus for treating a formation is disclosed that in one non-limiting embodiment includes a first string for placement in the wellbore that includes a first flow port that enables a treatment fluid to flow from inside the first string to the formation via an annulus between the first string and the formation, a second string for placement in the first string, wherein the second string includes a second flow port that supplies the treatment fluid to the first flow port along a selected radial orientation to direct the treatment fluid in the selected radial direction.

Apparatus and methods for oriented-fracturing of formations

In one aspect an apparatus for use in a wellbore is disclosed that in one non-limiting embodiment includes a completion assembly that contains a filter section having a tubular with a plurality of through holes filled with a filter material for restricting flow of solid particles through the holes for placement of the filter section across from a zone along the wellbore, a sensor inside the tubular for providing information about a parameter of interest during treatment of and/or production from the zone into the tubular, and a first circuit coupled to the sensor that transmits wireless signals corresponding to measurements made by the sensor to a second circuit that transmits the received signals to the surface.

Wellbore completion assembly with real-time data communication apparatus

An apparatus for use in a wellbore contains a flow control device for use in a wellbore that includes a bore that provides a first flow path and a second flow path via an annulus around the first flow path. The apparatus further includes a closing device that closes the second flow path when the closing device is mechanically moved in a first direction and an opening device that opens the second flow path when a fluid under pressure is supplied to the annulus when a valve is closed.

Wellbore strings containing annular flow valves and methods of use thereof

An isolation system is disclosed that contains: a lower wet connect portion, a central production tubing, an isolation device associated with the central production tubing, and at least one communication line, wherein the at least one communication line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further, a method for isolating a lower completion is disclosed that includes: conveying an isolation assembly to the lower completion, the isolation assembly including: a lower wet isolation device; and routing the at least one communication line through an inside diameter of the isolation device. Further a completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.

Wellbore isolation system with communication lines

In one aspect, a device for use in a wellbore includes a tubular body; a barrier member associated with an outer surface of the tubular body configured to retain a proppant; an actuating member associated with the barrier member configured to expand the barrier member in an annular direction; and a fluid channel associated with an upper extent and a lower extent of the barrier member, configured to allow a fluid flow therethrough. In another aspect, a method for completing a multi-zone wellbore, includes deploying a barrier device at a downhole location within the wellbore; expanding a barrier member in an annulus of the wellbore; providing proppant in the annulus of the wellbore; retaining the proppant in the annulus via the barrier member; and providing a fluid flow between an upper extent and a lower extent of the barrier member.

An isolation system is disclosed that contains a lower wet connect portion; a central production tubing; an isolation device associated with the central production tubing, and at least one control line. Further at least one control line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further method for isolating a lower completion is disclosed that includes conveying an isolation assembly to the lower completion, the isolation assembly including a lower wet connect portion, at least one control line, a central production tubing, and an isolation device, and routing the at least one control line through an inside diameter of the isolation device. Further completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.

Entry guides for use on a tubing string comprise one or more dissolvable materials. A profile disposed on the entry guide facilitates aligning the tubing string in a desired orientation within a wellbore. For example, the profile can align the tubing string with a bore of a component disposed within the wellbore so that the tubing string can be inserted into a bore of the downhole component. After proper alignment has been achieved, the one or more dissolvable materials can be activated to disappear leaving behind the tubing string and the downhole component in their desired arrangement. One or more portion of the entry guides, including the profile, can be formed out of the dissolvable material.

Expandable reamer apparatus for enlarging boreholes while drilling

An expandable reamer apparatus and methods for reaming a borehole are disclosed, including at least one laterally movable blade carried by a tubular body selectively positioned at an inward position and an expanded position. The at least one laterally movable blade, held inwardly by at least one blade-biasing element, may be forced outwardly by drilling fluid selectively allowed to communicate therewith or by at least one intermediate piston element. For example, an actuation sleeve may allow communication of drilling fluid with the at least one laterally movable blade in response to an actuation device being deployed within the drilling fluid. Alternatively, a chamber in communication with an intermediate piston element in structural communication with the at least one laterally movable blade may be pressurized by way of a movable sleeve, a downhole turbine, or a pump.

A one-trip system for placement and setting a downhole packer or plug is disclosed. The packer is settable in a variety of ways, including hydraulically, acoustically by pressure pulse signals, or some combination. Use of hydraulic pressure triggers a pressure-creating reaction to initiate the setting of the packer. The setting mechanism for the packer breaks clear of the packer upon setting and allows the tubing-conveyed perforating gun, which is already preassembled as part of the string, to be accurately positioned and fired.
