A wellbore material transfer system is disclosed, and comprises a downhole fluid conductor defining a downhole-conducting fluid passage, an uphole fluid conductor defining an uphole-conducting fluid passage, a flow controller for opening and closing the uphole-conducting fluid passage, and a completion disposed within a wellbore and defining a wellbore interval between the completion and the wellbore, the completion including selectively openable first and second flow communicators. While the flow communicators are open and the uphole-conducting fluid passage is closed, a subterranean formation zone may be fractured, and flow communication is absent, via the second flow communicator and the uphole-conducting fluid passage, between the wellbore interval and the surface. While the flow communicators and the uphole-conducting fluid passage are open, the wellbore interval may be gravel packed, and a solids-depleted fluid is conductible, via the second flow communicator and the uphole-conducting fluid passage, from the wellbore interval to the surface.

A method can include receiving production fluid flow rate data from a well in a field that includes a plurality of wells; generating a gas lift profile for the well using the production fluid flow rate data; solving a system of equations representing at least two gas lift profiles for at least two of the plurality of wells to generate results; and issuing an instruction based at least in part on the results to control gas lift for production of fluid by the well.

Provided is a downhole zonal isolation assembly. The downhole zonal isolation assembly, in accordance with one aspect, includes a rotating fracturing valve positionable within wellbore casing proximate a fracturing zone of interest. The downhole zonal isolation assembly, according to this aspect, further includes a rotating fracturing valve actuator coupled to the rotating fracturing valve, and rotating fracturing valve electronics coupled to the rotating fracturing valve actuator, the rotating fracturing valve electronics operable to activate the rotating fracturing valve actuator to move the rotating fracturing valve from a first wellbore casing open position to a second wellbore casing closed position.

A plunger lift system includes a bumper assembly to reduce the impact of the plunger at the bottom of the well and in some circumstances to reconfigure the plunger for the plunger's next ascent. The bumper assembly has a spring, a mandrel, an impact head, and a flow cage. The impact head and mandrel are constructed from a single piece of material thereby removing a joint between the impact head and mandrel. The unitary impact head/mandrel is connected to the flow cage using a first cooperating shoulder at the lower end of the unitary impact head/mandrel and a second cooperating shoulder within the flow cage. The first cooperating shoulder and the second cooperating shoulder are held in place with respect to each other by a force provided by the spring.

A sand collector including a diverter section and a filter section. The diverter section having a tubular portion with at least one aperture extending therethrough and at least one collector extending outwardly therefrom to cooperate with an exterior side of the tubular portion to form a channel in which solids traveling on the exterior side of the tubular portion from the upper end toward the lower end are guided to the aperture. The filter section having a tubular portion with an upper end, a lower end, and a sidewall extending between the upper end and the lower end. The filter section having at least one aperture extending through the sidewall, the upper end of the filter section extending from the lower end of the collector section and the lower end of the filter section being closed and connectable to at least one of another sucker rod and an upper end of a pump assembly.

A system and method for controlling production fluid flow between an annular chamber extending between a casing disposed in a downhole bore and production tubing disposed in the casing. An electrically down hole control valve which includes a motor, a position sensor, a gearbox and a linear actuator coupled to the gearbox to convert rotational movement to an axial movement. The control valve further includes a connecting rod coupled to the linear actuator and a valve assembly. The valve assembly includes a gate that can translate in an axial direction to a plurality of continuously variable positions between a fully closed position and a fully open position. A plurality of such control valves can be disposed in respective openings formed in the production tubing, and a passage is formed in each valve for connecting the annular chamber and the production tubing interior. The valves are selectively closed and selectively opened to permit fluid flow to and from the chamber, through the passage, and to and from the interior of the production tubing. Thus, the volume of fluid passing to and from the chamber, through the valve members, and to and from the interior of the production tubing is controlled.

A drive fluid inlet is at an uphole end of the submersible pump top drive. A removable hydraulic motor is driven by drive fluid received by the drive fluid inlet. The removable hydraulic motor is separable from a downhole pump. A receiver is at a downhole end of the hydraulic motor. The receiver is configured to mate with the downhole pump. A drive fluid outlet is configured to expel the drive fluid after the drive fluid has flowed through the hydraulic motor. The drive fluid outlet is downhole of the drive fluid inlet.

A valve assembly for integration within a wellbore string disposed within a subterranean reservoir is provided. The valve assembly includes a valve housing having one or more injection ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a valve sleeve operatively mounted within the valve housing and comprising a fluid channel adapted to establish fluid communication between the central passage and the injection ports, and configured to create a fluid flowrate restriction. The valve assembly has a flow adjuster connectable to the valve sleeve, and is selectively arranged to align an opening with the fluid channel and allow fluid to flow from the fluid channel through the opening to the injection port, wherein connecting the flow adjuster to the valve sleeve defines a flow length of the fluid channel to adjust the fluid restriction created by the fluid channel.
