  • REMOTELY CONTROLLED VALVE
    Publication number: 20180372236
    Abstract: A remotely controlled valve includes an electric motor and transmission for moving a valve stem or valve actuator. The operation of the motor may be controlled by a first input for power and analog signals. The valve is also provided with a programmable logic controller and a wireless module for receiving wireless control signals for controlling the operation of the motor which moves the valve stem or a valve actuator in a desired manner.

  • Electronic Switch and Circuit for Select-Fire Perforating Guns
    Publication number: 20120250208
    Abstract: Apparatus and method are provided for select-firing of perorating guns or activating other equipment in a well, such as a bridge plug. Double-pole double-throw electronic relays, used along with diodes that block voltage below a selected level, are used to control access of positive or negative voltages to blasting caps. Firing of a blasting cap causes an open circuit across the blasting cap and shifting of a relay. Alternate application of negative and positive voltages allows activation of multiple devices in a well.

  • Unlimited Downhole Fracture Zone System
    Publication number: 20110198096
    Abstract: Apparatus and method are provided for diverting treatment fluids in wells. Sliding sleeves or valves are sequentially opened by dropping balls that may be of uniform size. Opening of one valve moves a collet into position such that the same size ball can be used to open a second valve. Any selected number of valves can be opened with the same size balls. Systems using the valves are also disclosed, along with methods for operating.
