A communications path between a surface control system (142) and downhole equipment includes a network of wirelessly interconnected communication devices (114) that are located along a conduit (108). When the communications path fails or cannot be established during performance of a downhole operation, a mobile master communication tool (150) that is in communication with the surface system (142) can be deployed within the wireless range of one of the devices (114) to provide an alternative communication path between the surface system and the downhole equipment.

| Surface controlled subsurface control valves for use in wells and methods of controlling the same. In one embodiment, a valve includes a valve body, a bore closure assembly, a mechanical linkage, a drive assembly, and a control assembly. The valve body defines a bore for fluid to flow through when the bore closure assembly is in an open position. When the bore closure assembly is in its closed position, the bore closure assembly prevents fluid from flowing through the bore. The mechanical linkage is operatively connected to the bore closure assembly and to the drive assembly. The primary control assembly determines a force to apply to the mechanical linkage based on a present operating condition of the valve and causes the drive assembly to apply the determined force to the mechanical linkage. As a result, the mechanical linkage drives the bore closure assembly. | ||||||

| A well system is provided and configured for local and/or global control of a well. The well system may comprise one or more controllable downhole devices. Each of the downhole devices may include a telemetry module, an energy module configured to at least power an actuator, a controller communicably coupled to the telemetry module and one or more sensors, and a controllable component coupled to the actuator. The well system may further include a surface controller comprising a desired state input device configured to accept a desired state and then provide the desired state to the controller via the telemetry module. The controller may compare the desired state to an actual state determined by a sensor and instruct the actuator to adjust the controllable component such that the actual state approaches the desired state. The downhole device may operate autonomously after the initial setting of the desired state. | ||||||

| A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device.

Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool. Where the tools include sliding sleeves, the tools can be used to hydraulically fracture subterranean environs at spaced apart locations along a well bore in any desired sequence and without removing the tools from the well during the fracturing process. | ||||||

An electrically actuated valve and an electrical actuator (10) particularly suited for driving a valve are proposed for regulating a flow. The electrical actuator may include a gear reduction train (76), a brake (78) and a manual input override with clutch protection (80). The electrical actuator can be configured in three different operational modes that provides a predetermined position upon power loss including fail-bias fixed, fail open and fail bias closed. The electrical actuator can be driven for example by using the existing local power supply in wellhead valve systems, typically a solar panel (24) and a battery (26).

| A method and associated system for setting downhole control pressure. A method of setting a downhole control pressure includes the steps of : installing a pressure control system (24) with a pressure source (28); connecting a proximal end (26) of a line (22) to the pressure source (28) and a distal end to a well tool; calibrating the system by applying an overshoot pressure to the proximal end, then sensing a settled pressure in the proximal end resulting from the overshoot pressure, and determining a mathematical relationship between the overshoot and settled pressures. A system for setting a downhole control pressure includes a pressure source, a pressure limiter (30) and an interface for applying pressure to a proximal end of a control line and a well tool (16) connected to a distal end of the control line. The well tool is operated in response to a predetermined settled pressure achieved at the distal end in response to an overshoot pressure being applied to the proximal end and the pressure limiter limiting application of pressure from the pressure source to the proximal end to the overshoot pressure. | ||||||
