    摘要： Methods and apparatus for actuating a downhole tool in wellbore includes acquiring a CCL data set or log from the wellbore that correlates recorded magnetic signals with measured depth, and selects a location within the wellbore for actuation of a wellbore device. The CCL log is then downloaded into an autonomous tool. The tool is programmed to sense collars as a function of time, thereby providing a second CCL log. The autonomous tool also matches sensed collars with physical signature from the first CCL log and then self-actuates the wellbore device at the selected location based upon a correlation of the first and second CCL logs.

    摘要： A communications module and methods for downhole operations having utility with production of hydrocarbon fluids from a wellbore, including at least one alternate flow channel and an electrical circuit. Generally, the electrical circuit is pre-programmed to (i) receive a signal and, in response to the received signal, deliver an actuating command signal. The communications module further has a transmitter-receiver. The communications module allows a downhole tool to be actuated within a completion interval of a wellbore without providing an electric line or a working string from the surface. The tool may be actuated in response to a reading from a sensing tool, or in response to a signal emitted in the wellbore by a downhole carrier, or information tag.
