SELECTIVE CONNECTION OF DOWNHOLE REGIONS
A method and apparatus for selectively connecting a first fluid communication region to a further fluid communication region are disclosed. The apparatus comprises an elongate housing, locatable in a wellbore, comprising a first end portion associated with a first fluid communication region; a sheath member axially slidable within the housing and biased towards the first end portion via at least one biasing element; and an elongate shuttle member axially slidable within the housing and slidably locatable in a sealed relationship or non-sealed relationship with the sheath member; wherein the biasing element provides a predetermined biasing force that determines a threshold pressure which must be exceeded by a fluid pressure in the first fluid communication region to permit axial movement of the sheath member away from the first fluid communication region or towards a further fluid communication region.

LINER HANGER RUNNING TOOL
Liner hanger running tool (LHRT) having a mandrel with a central through-bore includes a transducer configured to identify a predetermined activation signal and, based on receipt of the predetermined activation signal, transmit an actuation signal. The LHRT also includes a power source. In addition, the LHRT includes a valve. Further, the LHRT includes an actuator configured to be operated by the power source and activated by the actuation signal from the transducer to close the valve in the central through-bore in the mandrel.
DOWNHOLE TORQUE LIMITER
Provided, in one aspect, is a downhole torque limiter, comprising a tubular housing; a pipe positioned within the tubular housing; one or more clutch mechanisms positioned between the pipe and the tubular housing, the one or more clutch mechanisms configured to move between a engaged state to fix the tubular housing relative to the pipe and a disengaged state to allow with the tubular housing to rotate relative to the pipe; and a fluid control system coupled with an exterior of the one or more clutch mechanisms, the fluid control system configured to allow the one or more clutch mechanisms to move from the engaged state to the disengaged state based upon sensing movement of the pipe relative to the tubular housing.
Systems and methods for opening screen joints
Example systems and methods are described that operate to open screen joints using mechanically-generated perforations for beginning fluid production. In an example system, a screen joint is deployed in a production tubing within a wellbore. The screen joint includes a screen element and a blank housing that are coupled to an exterior surface of a non]perforated base pipe. Further, the screen joint includes a locator profile positioned along an interior surface of the non]perforated base pipe. A perforator is deployed within the screen joint that includes a mechanical perforator and a locator for engaging with the locator profile to position the mechanical perforator under the blank housing.

Device and method to trigger, shift, and/or operate a downhole device of a drilling string in a wellbore
A downhole device and method to trigger, shift, and/or operate a downhole device of a drilling string in a wellbore is disclosed. At a high level, the disclosed device causes a portion of drilling fluids to bypass the drill bit and into the annulus. The bypass may be triggered upon certain conditions related to the rotation speeds of the drill string or other conditions such as the pressure of the drilling fluids. For example, the drill string may be rotated in some protocol of operation (e.g., stop at certain rpm, and/or stop at certain other rpm) to describe a recognizable series of signals to an accelerometer and/or microprocessor that will communicate to pumps or valves to operate or pause/stop operations.

Inflow control system
A technique facilitates the production of well fluid. According to an embodiment, an inflow assembly may be deployed downhole with, for example, completion equipment used in the production of well fluid. The inflow assembly comprises a first inflow control device and a second inflow control device disposed in series along a flow path routed between an exterior and an interior of the inflow assembly. As well fluid flows into an interior of the inflow assembly along the flow path, the first inflow control device and the second inflow control device perform different tasks with respect to controlling fluid flow. The different tasks may be selected to, for example, facilitate production of well fluid while protecting the completion equipment.
Wellbore Production Method and System Using Bailer
Hydrocarbons are produced from a wellbore using a wand member supported within the top end of the casing and a bailer vessel supported within the casing of the wellbore to reciprocate between (i) a lower position submerged in the hydrocarbon fluids at a predetermined depth within the casing such that fluids enter a production chamber of the bailer vessel and (ii) an upper position receiving the wand member therein through an open top of the bailer vessel so as to force the hydrocarbon fluids in the production chamber under pressure through a bottom opening in the wand member and into a receiving chamber of the wand member. The hydrocarbons in the wand member are then discharged to a location externally of the casing for storage.
