Tension release packer for a bottomhole assembly and methods of use

In the absence of a pressure equalization valve or flow passages through the packer, the annular passageway equalizes pressure differentials across the packer element allowing a tool, in which the packer is incorporated, to be moved in the wellbore with little or no damage to the packer element and further, allows debris to flow from above the packer to below the packer.

A sleeve assembly has a sleeve axially moveable within a housing, the sleeve being positively locatable within a wellbore for reliable axial shifting of the sleeve between an uphole position and a downhole position. Stops and shoulders, which delimit the shifting of the sleeve between open and closed positions, are located in an annulus between the sleeve and the housing. Uphole and downhole ends of the sleeve and the housing have opposing ramps formed thereon. Locating shifting tools run through the sleeve assembly are engageable only in a locating profile in the sleeve and cannot engage in the annular stops or in gaps formed in the bore, uphole and downhole of the sleeve, as the ramps act to guide the locating tool therethrough. As the uphole and downhole sleeve ramps converge toward either of the uphole or downhole housing ramps during shifting thereof, debris is diverted into the bore allowing the sleeve to shift fully uphole or downhole.

E21B 44/00 - Automatic control systems specially adapted for drilling operations, i.e. self-operating systems which function to carry out or modify a drilling operation without intervention of a human operator, e.g. computer-controlled drilling systemsSystems specially adapted for monitoring a plurality of drilling variables or conditions
Embodiments of a bottomhole assembly (BHA) for completion of a wellbore are deployed on electrically-enabled coiled tubing (CT) and permit components of the BHA to be independently electrically actuated from surface for completion of multiple zones in a single trip using a single BHA having at least two electrically-actuated variable diameter packers. One or both of the packers may be actuated to expand or retract for opening and closing off a variety of flowpaths between the BHA and the wellbore, in new wellbores, old wellbores, cased wellbores, wellbores with sleeves and in openhole wellbores. Additional components in the BHA, which may also be electrically-actuated or powered, permit perforating, locating of the BHA in the wellbore such as using casing collar locators and microseismic monitoring in real time or in memory mode.

Downhole sleeve assembly and sleeve actuator therefor
A bottom hole actuator tool for locating and actuating one or more sleeve valves spaced along a completion string. A shifting tool includes radially extending dogs at ends of radially controllable, and circumferentially spaced support arms. Conveyance tubing actuated shifting of an activation mandrel, indexed by a J-Slot, cams the arms radially inward to overcome the biasing for in and out of hole movement, and for releasing the arms for sleeve locating and sleeve profile engagement. A cone, movable with the mandrel engages the dogs for positive locking of the dogs in the profile for sleeve opening and closing. A treatment isolation packer can be actuated with cone engagement. The positive engagement and compact axial components results in short sleeve valves.

DOWNHOLE OPERATIONS USING REMOTE OPERATED SLEEVES AND APPARATUS THEREFOR
One or more remote-operated sleeve valves are placed along a tubular string downhole. The sleeves can be opened and closed wirelessly, and in embodiments over and over again. Differential pressure between wellbore fluid pressure and an accumulator chamber enable repeated shifting. Each sleeve can have a unique actuation code removing constraints regarding sequence of operation and need for well intervention to access the sleeves. Hydraulic fracturing can be achieved without wellbore obstructions, and other operations benefit for reduced expense in service rigs and the ability or selectively shut off problem zones. Remote signals received downhole include those generated by percussive and seismic, distinguishable from background noise including during pumping.

Extendable/collapsible apparatus for fracture imaging and use of same
Fracture imaging modules having one or more 3-component sensors, are incorporated into a tool comprising two or more of the modules for detecting microseismic events in a formation from the same wellbore as is being stimulated. The modules are locked together in a compact mode to permit injection into the wellbore through a conventional lubricator which has a fixed length. Once injected into the wellbore, the modules are spaced from one another in an extended mode to form an axially spaced sensor array which increases the measurement window in the wellbore compared to sensor arrays conventionally injected through a fixed length lubricator. Following the operation, the modules are actuated to return to the compact mode for pulling out of the hole through the lubricator.
A bottom hole actuator tool is provided for locating and actuating one or more sleeve valves spaced along a completion string.

Microseismic monitoring with fiber-optic noise mapping
The combination of one or more 3-component microseismic sensors deployed into a wellbore adjacent a microseismic event and a linear array of distributed fiber optic acoustic sensors deployed uphole thereof provides two sets of data for establishing noise-free signals for locating the microseismic event in the formation about the wellbore. The distributed fiber optic signals monitor noise transmitted along coiled tubing used to pump a completion operation or as a result of the fluid flowing through the casing or coiled tubing, or along wireline used to deploy the microseismic sensors. The noise is mapped and extrapolated for estimating noise at the 3-component sensors. The estimated noise is removed from the 3-component sensor data for producing clean signals representing the location of the microseismic events.
