    Abstract: This system invention relates to the use of short hop communications to transfer data between 2 modules inside a well. A system deployed in a well permanently or semi-permanently collects data from downhole parameters such as pressure, temperature, vibration, flow and fluid identification and stores the information in the system memory. The receiver module is deployed in the well via slick line, electric line or coil tubing with the purpose of retrieving the data from the system memory by interfacing with the downhole module via wireless short hop communications. The receiver module can also send commands into the downhole module to change its data collection parameters. Upon completion of the data transfer, the collector is returned to the surface where the data is again wirelessly transferred to a processing system such as a Personal Computer.

    Abstract: A system for harvesting energy from the operation of a downhole jar is disclosed. The system converts the kinetic energy associated with the operation of the jar to electrical energy by associating the relative movement between a magnet and a coil to the relative movement between a movable member and a stationary member in the jar. Electrical energy is generated in the coil as a result of the relative motion between the magnets and the coil. This electrical energy may be stored in an electrical energy storage subsystem and provided to a downhole tool for use in the wellbore. The downhole tool may be used to power other tools, to take measurements, to communicate with other devices, to actuate other devices, and to otherwise control such other devices.

    Abstract: A method and apparatus for charging a bulk energy storage capacitor, such as used for actuating solenoids in downhole tools. An electrical generator, which may be a mud-powered, provides a rectified voltage proportional to its rotational speed. The rectified voltage is fed to a single-ended primary-inductor converter, which in turn charges the bulk capacitor 16 when the voltage across the bulk capacitor falls between predetermined upper and lower set points. Upon discharging the bulk capacitor, such as from actuation of solenoid valves for creating mud pressure pulses, control logic also causes the converter to cease charging the bulk capacitor 16 to enhance circuit efficiency and performance. A battery may also be provided to charge the bulk capacitor via a current limiter, and a disconnect circuit prevents the battery from charging the bulk capacitor when the generator is charging the bulk capacitor via the converter.
