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.

Claims (41)

1 . 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.

2 . The method of claim 1 , further comprising:

receiving additional instructions from the gauge surface readout for processing the given parameter within a second range of the variable, which is different from the first range.

3 . The method of claim 2 , wherein the second range is narrower than the first range.

4 . The method of claim 1 , wherein the given parameter is one or more of: a vibration level, a rotation speed of a motor of the ESP, vibrations root mean square (rms) velocity, vibrations peak acceleration, or vibrations Kurtosis.

5 . The method of claim 4 , wherein the variable is a rotation frequency.

6 . The method of claim 1 , further comprising:

adjusting an operation of the ESP based on the displayable results.

7 . The method of claim 1 , wherein the step of measuring the given parameter includes:

measuring a vibration of the ESP with a sensing device including one or more of an accelerometer, a MEMS, or an acoustic sensor.

8 . The method of claim 7 , wherein the sensing device is directly located on the analysis enabled gauge.

9 . The method of claim 7 , wherein the sensing device is directly located on the ESP.

10 . A method for downhole analysis at a gauge surface readout associated with an electric submersible pump, ESP, the method comprising:

transmitting instructions, to an analysis enabled gauge, 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;

receiving displayable results, along a power cable of the ESP, processed by the analysis enabled gauge, based on raw data associated with measurements performed downhole on the ESP with a frequency in the kHz to MHz range, on the given parameter, wherein the displayable results have a smaller digital footprint than the raw data; and

sending additional instructions to the analysis enabled gauge for processing the given parameter for a second range of the variable, which is different from the first range,

wherein the power cable has a data transmission speed in a range of bits per second.

11 . The method of claim 10 , wherein the second range is narrower than the first range.

12 . (canceled)

13 . The method of claim 10 , wherein the given parameter is one or more of: a vibration level, a rotation speed of a motor of the ESP, vibrations root mean square (rms) velocity, vibrations peak acceleration, or vibrations Kurtosis.

14 . The method of claim 13 , wherein the variable is a rotation frequency.

15 . The method of claim 10 , further comprising:

adjusting an operation of the ESP based on the displayable results.

16 . A downhole analysis system comprising:

an analysis enabled gauge configured to work with an electric submersible pump, ESP;

a gauge surface readout in communication with the analysis enabled gauge; and

a power cable connecting the gauge surface readout to the analysis enabled gauge, wherein the power cable has a data transmission speed in a range of bits per second,

wherein the analysis enabled gauge is configured to,

receive instructions from the 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;

measure the given parameter with a frequency in the kHz to MHz range and generate associated raw data;

downhole process the given parameter, within the first range of the variable, to generate displayable results, which have a smaller digital footprint than the raw data; and

transmit the displayable results to the gauge surface readout along the power cable of the ESP.

17 . The system of claim 16 , wherein the analysis enabled gauge is further configured to,

receive additional instructions from the gauge surface readout for processing the given parameter within a second range of the variable, which is different from the first range.

18 . The system of claim 17 , wherein the second range is narrower than the first range.

19 . The system of claim 16 , wherein the given parameter is one or more of: a vibration level, a rotation speed of a motor of the ESP, vibrations root mean square (rms) velocity, vibrations peak acceleration, or vibrations Kurtosis.

20 . The system of claim 19 , wherein the variable is a rotation frequency.
