Abnormal operating condition validation system for saltwater disposal pump systems and methods of use thereof

A method for validating abnormal operating conditions of a saltwater disposal pump system, the method comprising the steps of:

• receiving an alarm from a saltwater disposal pump assembly that exceeds a predetermined alarm level indicative of an abnormal machine operation, the saltwater disposal pump assembly comprising:
• an inlet valve;
• a saltwater tank fluidly coupled to the inlet valve, the saltwater tank configured to retain a saltwater;
• at least one pipe fluidly coupled to the saltwater tank;
• an outlet valve fluidly coupled to a portion of the at least one pipe;
• a recycle valve assembly fluidly coupled to the at least one pipe;
• a pump having a motor and fluidly coupled to the at least one pipe and the recycle valve assembly, the pump configured to generate a pressure within the at least one pipe such that the saltwater retained in the saltwater tank is forced through the pump and into a well site under pressure;
• and
• a plurality of sensors configured to sense a plurality of data, the plurality of data comprises a suction strainer differential pressure, a suction flow, a discharge pressure, a suction pressure, a vibration, and a temperature;
• receiving the plurality of data from the plurality of sensors indicative of a current operating conditions of the saltwater disposal pump assembly;
• deriving an expected value for the plurality of data utilizing a statistical regression analysis, wherein the statistical regression analysis comprises at least one statistical regression formula, the at least one statistical regression formula comprises the plurality of data from the suction strainer differential pressure, the suction flow, the discharge pressure, the suction pressure, the vibration, and the temperature as variables for the statistical regression analysis;
• determining whether the expected value and a history of the plurality of data correlate at a point where the plurality of data exceeds the predetermined alarm level indicative of the abnormal machine operation;
• in response to determining that the expected value and the history of the plurality of data correlate at the point where the plurality of data exceeds the predetermined alarm level indicative of the abnormal machine operation, determining whether a deviation from a predefined operating profile exceeds a predetermined machine data validation threshold value;
• in response to determining that the deviation from the predefined operating profile exceeds the predetermined machine data validation threshold value, validating the alarm received from the saltwater disposal pump assembly indicative of the abnormal machine operation;
• outputting an alert of the deviation;
• and
• inhibiting a further operation of the saltwater disposal pump assembly.
