摘要： Liquid is unloaded from a well with a hybrid gas lift system that includes a lift gas source and valves for injecting lift gas into production tubing. The types of valves include pressure production operated (“PPO”) valves and a surface operated valve. Pressure inside the production tubing is measured to monitor operation of the PPO valves, and identify if the PPO valves are experiencing and anomaly, such as multi-pointing or chattering. The surface operated valve is selectively actuated to correct anomalous operation of the PPO valves.

摘要： A lift gas injection system that is used for introducing lift gas into a stream of production fluid includes a lift gas injection valve. A pressure protection system guards the injection valve against external overpressure by blocking communication to inside the injection valve housing when ambient pressure exceeds a set pressure. Communication is blocked by moving a valve member so that it obstructs flow through an opening in the housing. The system includes pressure actuated valve which has a platen mounted to an end of a bellows, and a valve member coupled to the platen. Surface area is reduced on the bellows side of the platen that creates a force imbalance on the platen from applied ambient pressure. At the set pressure the force imbalance moves the platen, and which pushes the valve member against the opening. A compressible pressure compensator inside the injection valve protects against internal overpressure.

摘要： A bi-directional valve with valve elements having compliant features biasing them together to maintain a sealing interface that defines a fluid communication barrier within the valve. Parting the valve elements from one another removes the sealing interface allow fluid communication across the valve elements. The valve includes a side port and a choke member that selectively blocks fluid flow through the valve when moved adjacent the side port and selectively opens the valve to fluid communication when moved away from the side port. The choke member remains adjacent the side port until the valve elements are spaced a distance apart greater than that at which valve erosion or fluid cavitation occurs.

摘要： An annulus safety valve assembly for controlling gas flow in a wellbore annulus that includes a passage, a check valve in the passage, and an actuator that is selectively changed between first and second states. The actuator is bi-stable, and requires no energy to remain in either state. When the actuator is put into one of the states, the check valve configuration is changed from one way flow to two way flow. Reconfiguring the check valve into the two way flow configuration vents lift gas from inside the annulus that is below the check valve.

摘要： An apparatus for producing fluid from a wellbore includes production tubing in the wellbore, an annulus around the tubing, and a chemical injection system for injecting chemical additive into the production tubing from the annulus. The chemical additive system includes an injection module with a valve that is selectively opened and closed by operating an actuator. When the valve is opened, the chemical additive is injected into the tubing in response to a pressure differential between the annulus and tubing. The injection module is surface-controlled and downhole conditions are monitored, so that a flow of chemical additive injection is initiated, adjusted, or suspended in real time.

摘要： Fluid is produced from a well that is equipped with a plunger lift system. The plunger lift system includes a plunger that is inserted into production tubing that is installed in the well. Liquid from a surrounding formation accumulates on top of the plunger. The liquid accumulation on the plunger is monitored. Lift gas is injected into the production tubing below the plunger to lift the plunger and accumulated liquid to surface. A wellhead assembly at surface directs the accumulated liquid away from the well, and injection of the lift gas is suspended to allow the plunger to drop back to its initial position. The timing of the lift gas injection is based on monitoring liquid accumulation, and also to maximize production from the well.

摘要： A method and system of producing fluid from a well with a gas lift system that includes a virtual plunger made from a plunger forming material. The virtual plunger is formed downhole by injecting the plunger forming material directly into a column of liquid inside production tubing and from an annulus that circumscribes the production tubing. The flow of plunger forming material into the production tubing is controlled by an injection valve intersecting a sidewall of the production tubing. The plunger forming material is added to the annulus from the surface, and enough is added so its upper level is above the injection valve. Adding injection gas to the production tubing below the virtual plunger pushes the virtual plunger and column of liquid to surface. The plunger forming material has properties so that the virtual plunger remains cohesive while traveling uphole.

摘要： A well system having a wellbore that intersects a subterranean formation, a valve station in the wellbore, and a primary controller on surface that communicates with the valve station using wireless telemetry. The valve station includes a valve member that controls a flow of fluid in the wellbore, an actuator for operating the valve member, and a valve controller that provides command signals to the actuator for positioning the valve member. The primary controller sends command signals that are receivable when the telemetry is operational. The valve controller is programmed to control operation of the valve actuator and valve member when telemetry is suspended and so that the valve station operates autonomously when out of signal communication with the primary controller and until signal communication is reestablished.
