Description
SYSTEM AND METHOD FOR COMPREHENSIVE
FRACTURING PUMP OPERATION MONITORING
FIELD
The present disclosure relates to sensors and monitoring devices and systems, and in particular, to a system and method for comprehensive fracturing pump operation monitoring.
BACKGROUND
Hydraulic fracturing is a process to obtain hydrocarbons such as natural gas and petroleum by injecting a fracking fluid or slurry at high pressure into a wellbore to create cracks in deep rock formations. The hydraulic fracturing process employs a variety of different types of equipment at the site of the well, including one or more positive displacement pumps, slurry blender, fracturing fluid tanks, high-pressure flow iron (pipe or conduit), wellhead, valves, charge pumps, and trailers upon which some equipment are carried.
Positive displacement or reciprocating pumps are commonly used in oil fields for high pressure hydrocarbon recovery applications, such as injecting the fracking fluid down the wellbore. A positive displacement pump may include one or more plungers driven by a crankshaft to create a high or low pressure in a fluid chamber. A positive displacement pump typically has two sections, a power end and a fluid end. The power end includes a crankshaft powered by an engine that drives the plungers. The fluid end of the pump includes cylinders into which the plungers operate to draw fluid into the fluid chamber and then forcibly push out at a high pressure to a discharge manifold, which is in fluid communication with a well head.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a simplified block diagram of an exemplary embodiment of a system and method for comprehensive monitoring of a positive displacement pump according to the teachings of the present disclosure; and FIG. 2 is a pictorial representation of an exemplary positive displacement pump as an exemplary monitoring subject for a system and method for comprehensive monitoring according to the teachings of the present disclosure.
DETAILED DESCRIPTION
The system and method for comprehensive monitoring may be used on a number of different pieces of equipment commonly found at a hydraulic fracturing site, such as positive displacement pumps, slurry blender, fracturing fluid tanks, high-pressure flow iron (pipe or conduit), charge pump (which is typically a centrifugal pump), trailers upon which some equipment are carried, valves, wellhead, conveyers, and other equipment. It is desirable to monitor the operation of these equipment so that timely inspection, maintenance, and replacement can be scheduled to ensure optimal operations. The system and method described herein can be used to monitor the operations of these different types of equipment used for hydraulic fracturing. Currently, no reliable data is available relating to the operations of these equipment so that equipment servicing tasks can be scheduled in a timely and optimal manner. Further, operation data can be easily falsified to benefit from warranty programs if no accurate data is available.
FIG. 1 is a simplified block diagram of an exemplary embodiment of a system and method 100 for comprehensive monitoring of a positive displacement pump according to the teachings of the present disclosure.

3 PCT/US2020/021928 (e.g., mounted on the metal housing of the fluid end of the pump to sense and measure the amount of flex in the housing due to pressure fluctuations of the fluid inside the fluid end), pressure sensor, accelerometer, vibration sensor, piezoelectric element, proximity sensor, linear variable displacement transducer (LVDT), load cell, and flow meter. The system 100 may include one or more of these sensors/devices. Pressure could also be obtained by using load cells located in close proximity to the bore but not necessarily in direct contact with the frac fluids.
The microcontroller 102 includes or is in communication with non-volatile memory devices 108 such as a FRAM (ferroelectric random-access memory) and flash memory.
Alternatively, a memory device located externally, such as a flash drive or an SD card, may be used to store data from the microcontroller 102. The microcontroller 102 also receives an accurate real-time clock signal from a real-time clock 110. The microcontroller 102 is coupled to a display 112, which is used to present the hour, cycle count, and duty cycle data generated by the microcontroller 102, as well as to enable a user to perform diagnostics, change system settings, etc. A voltage regulator 114 is configured to supply a constant voltage level to a battery charger 116, which in turns supplies power to charge a battery 118 that is at least one of the power source for the microcontroller 102 and other circuit elements in the system 100. The microcontroller 102 may also be coupled to a wireless communication interface 120 that enable it to receive commands/instructions/code updates as well as transmit the hour, cycle count, and duty cycle data to an external/remote device that can be accessed by a user. The wireless communication interface may comprise Bluetooth, WiFi, cellular, and other technologies, Not shown explicitly, the microcontroller 102 may also be coupled to ADC
(analog-to-digital converter), DAC (digital-to-analog converter), one or more data communication interfaces such as UART (Universal Asynchronous Receiver-Transmitter), IrDA
(Infrared Data Association), and SPI (Serial Peripheral Interface), I2C (Integer-Integrated Circuit), etc.
to process/transmit/supply input and output to and from the microcontroller 102.
Accordingly, the system and method 100 described herein are configured to measure, obtain, and determine a number of operating parameters of a frac pump: number of operating hours, cycle count, and the duty cycle. For purposes of this disclosure, the number of operating hours is defined as the amount of time, in hours, that the pump is operating equal or above a certain predetermined speed threshold, for example 20 RPM. The cycle count is the number of times that a crankshaft of the pump has gone through a whole cycle. The duty cycle is the percentage of total time that the pump is in operation measured as in operation within a certain discharge fluid pressure range. Preferably, a desired output is a histogram of cycle count and operating hours for predetermined ranges of pump discharge pressure. For example, the pump may determine the pump cycle count and operating hours where the pump discharge pressure < 10,000 psi, 10,000 - 11,000 psi, 11,000 ¨ 12,000 psi, 12,000 ¨
13,000 psi, etc.
FIG. 2 is a pictorial representation of an exemplary positive displacement pump 200 as an exemplary monitoring subject for the system and method 100 described herein. The positive displacement pump 200 has two sections, a power end 202 and a fluid end 204. The fluid end 204 of the pump includes a fluid end block or fluid cylinder, which is connected to the power end housing via a plurality of stay rods 206. In operation, the crankshaft (not explicitly shown) reciprocates a plunger rod assembly between the power end 202 and the fluid end 204. The crankshaft is powered by an engine or motor (not explicitly shown) that drives a series of plungers (not explicitly shown) to create alternating high and low pressures inside a fluid chamber in the fluid end that entered the fluid end via a suction manifold 208.
The cylinders operate to draw fluid into the fluid chamber and then discharge the fluid at a high pressure to a discharge manifold 210. The discharged liquid is then injected at high pressure into an encased wellbore. The injected fracturing fluid is also commonly called a slurry, which is a mixture of water, proppants (silica sand or ceramic), and chemical additives. The pump 200 can also be used to inject a cement mixture down the wellbore for cementing operations. The pump 200 may be freestanding on the ground, mounted to a skid, or mounted to a trailer.
Although described in the context of monitoring a frac pump, the system and method may be used to monitor a variety of equipment at a fracturing site. The system and method may also be used to monitor the operations of a slurry blender, fracturing fluid tanks, high-pressure flow iron (pipe or conduit), trailers upon which some equipment are carried, valves, wellhead, charge pump (typically a centrifugal pump), conveyers, and other equipment at the site of a hydraulic fracturing operation or other types of hydrocarbon recovery operations.
The microcontroller 102 includes or is in communication with non-volatile memory devices 108 such as a FRAM (ferroelectric random-access memory) and flash memory.
Alternatively, a memory device located externally, such as a flash drive or an SD card, may be used to store data from the microcontroller 102. The microcontroller 102 also receives an accurate real-time clock signal from a real-time clock 110. The microcontroller 102 is coupled to a display 112, which is used to present the hour, cycle count, and duty cycle data generated by the microcontroller 102, as well as to enable a user to perform diagnostics, change system settings, etc. A voltage regulator 114 is configured to supply a constant voltage level to a battery charger 116, which in turns supplies power to charge a battery 118 that is at least one of the power source for the microcontroller 102 and other circuit elements in the system 100. The microcontroller 102 may also be coupled to a wireless communication interface 120 that enable it to receive commands/instructions/code updates as well as transmit the hour, cycle count, and duty cycle data to an external/remote device that can be accessed by a user. The wireless communication interface may comprise Bluetooth, WiFi, cellular, and other technologies, Not shown explicitly, the microcontroller 102 may also be coupled to ADC

(Infrared Data Association), and SPI (Serial Peripheral Interface), I2C (Integer-Integrated Circuit), etc.
to process/transmit/supply input and output to and from the microcontroller 102.
Accordingly, the system and method 100 described herein are configured to measure, obtain, and determine a number of operating parameters of a frac pump: number of operating hours, cycle count, and the duty cycle. For purposes of this disclosure, the number of operating hours is defined as the amount of time, in hours, that the pump is operating equal or above a certain predetermined speed threshold, for example 20 RPM. The cycle count is the number of times that a crankshaft of the pump has gone through a whole cycle.
