A hydraulically set packer assembly actuated over an electronic line. The assembly includes a hydraulic packer setting mechanism that serves as an intensifier that is activated by way of an electronic trigger. As such, the trigger may be electronically coupled to an electronic line that is conventionally available for surface communications between surface equipment and a downhole gauge. The gauge generally present for monitoring well conditions such as pressure. Thus, a separate dedicated hydraulic or other powering line need not be outfitted as part of the assembly. Once more, for sake of gauge and well monitoring integrity, communications with the setting mechanism may be severed upon setting of the packer.

To communicate measurement data from a well, data corresponding to measurement data collected by multiple sensors in a well is transformed downhole and passed to an intermediate communications device, which device in turn passes a subset of that data to a destination communications device. The destination communications device applies a second transformation to the data received from the intermediate communications device. The first and second transformations are designed such that meaningful data can be recovered at the destination communications device even though only a subset of the original transformed data has been received.
