Data memory unit for electric submersible pumping system

A method for storing data for a pumping system from one or more sources, the method comprising the steps of:

• recording data from a sensor within the pumping system at a first frequency, wherein the data is recorded within a volatile memory module of an onboard data memory unit within the pumping system;
• aggregating the data recorded at the first frequency within the volatile memory module on a rolling average basis;
• moving the aggregated data to a non-volatile memory module within the onboard data memory unit;
• detecting the occurrence of a frequency shifting event;
• automatically changing the storage location of the data recorded at the first frequency from the volatile memory module to the non-volatile memory module for the duration of the frequency shifting event.

A method for storing data for a submersible pumping system from one or more sources, the method comprising the steps of:

• outputting measurement data from a sensor within the submersible pumping system;
• receiving or retrieving the measurement data at a data memory unit within the submersible pumping system;
• storing the measurement data in a volatile memory module within the data memory unit;
• aggregating the measurement data in the volatile memory module;
• moving the aggregated measurement data in a non-volatile memory module;
• recording additional measurement data at the volatile memory module of the data memory unit within the submersible pumping system;
• detecting the occurrence of a frequency shifting event;
• and
• automatically transferring the additional measurement data in an unaggregated form from the volatile memory module to the non-volatile memory module.
