Abstract
A method for downhole analysis at an analysis enabled gauge associated with an electric submersible pump, ESP, includes: receiving instructions from a gauge surface readout for measuring downhole a given parameter of the ESP as a function of a variable, measuring the given parameter, downhole processing the given parameter, for a first range of the variable, to generate results, and transmitting the results to the gauge surface readout along a power cable of the ESP.

A method for downhole analysis at an analysis enabled gauge associated with an electric submersible pump, ESP, the method comprising:
- receiving instructions, from a gauge surface readout, for (1) measuring downhole a given parameter of the ESP as a function of a variable, and (2) processing the given parameter for a first range of the variable;
- measuring the given parameter with a frequency in the kHz to MHz range and generating associated raw data;
- downhole processing the raw data associated with the given parameter, for the first range of the variable, to generate displayable results, which have a smaller digital footprint than the raw data;
- and
- transmitting the displayable results to the gauge surface readout along a power cable of the ESP, wherein the power cable has a data transmission speed in a range of bits per second.
