Definitions
- an artificial lift mechanism that utilizes a pump is sometimes used.
- One type of pump is an electrical submersible pump that can be operated at different frequencies.
- the electrical submersible pump can be controlled by a variable speed drive system that is able to vary the operational frequency of the electrical submersible pump.
- the resonance frequency of an object is the natural frequency of vibration of the object, determined by the physical parameters of the object.
- a manual procedure is performed.
- the manual procedure involves controlling the variable speed drive system (normally located at the earth surface) to perform a frequency sweep of the electrical submersible pump.
- the vibration of the electrical submersible pump is monitored by the well operator over the frequency sweep. Normally, the frequency associated with the maximum amount of vibration is considered the resonance frequency, which is recorded by the well operator conducting the test.
- the variable speed drive system is then manually set to skip the resonance frequency during normal operation of the electrical submersible pump.
- a downhole system e.g., an electrical submersible pump
- a drive system controls an operating frequency of the downhole system.
- a controller controls the drive system to, in a test procedure, vary the operating frequency of the downhole system, and to automatically detect a resonance frequency of the downhole system in the test procedure.
- the controller is also able to set the detected resonance frequency as an operating frequency to avoid.
- FIG. 1 illustrates a system with a pump located in a wellbore and a surface variable frequency drive and control system having a module to determine a resonance frequency of the pump, according to an embodiment.
- FIG. 2 is a flow diagram of a process of detecting the resonance frequency of the pump of FIG. 1 , according to an embodiment.

- the control module 126 includes a controller 128 and the variable speed drive system 130 . Note that other components (not shown) can also be part of the control module 126 .
- the variable speed drive system 130 controls the speed at which the motor 114 runs. The speed control affects the operating frequency of the electrical submersible pump assembly 102 .
- the variable speed drive system 130 is connected to the controller 128 , which controls (among others) the speed variation provided by the variable speed drive system 130 .
- the variable speed drive system 130 also provides protection functions for the submersible pump assembly 102 .
- the controller 128 includes a resonance frequency detection software 134 that is executable on a central processing unit (CPU) 136 .

- the resonance frequency detection software 134 provides an automated mechanism for automatically detecting the resonance frequency of the electrical submersible pump assembly 102 (or other type of downhole tool that is capable of operating at multiple frequencies).
- Using the resonance frequency detection software 134 in the controller 128 to perform the resonance frequency detection enables a well operator to automate the resonance frequency detection procedure, such that the well operator does not have to manually detect for the resonance frequency and to make adjustments in the variable speed drive system 130 for such resonance frequency.
- the resonance frequency detection software 134 works with an electric submersible pump assembly 102 that includes a downhole sensor module that is able to measure vibration at any point on the submersible pump assembly 102 .
- the resonance frequency detection software 134 is executable to detect the resonance frequency of the electrical submersible pump assembly 102 , and to automatically set one of the resonance frequencies that the variable speed drive system 130 will skip, called “setting a jump frequency.”
- a user station 132 can be coupled to the control module 126 .
- a user such as a well operator
- the user can invoke execution of the resonance frequency detection software 134 as well as view the results of the execution of resonance frequency detection software 134 .

- a downhole sensor module 118 is provided in the electrical submersible pump assembly 102 .
- the downhole sensor module 118 is connected to the cable 120 through the motor 104 , while one or more transducers can be located at any point on the electrical submersible pump assembly 102 .
- the resonance frequency detection software 134 is executable to receive or generate (at 202 ) minimum and maximum operating frequency values that define a frequency range over which a frequency sweep is to be performed in the test procedure.
- the minimum and maximum operating frequencies can be entered by a user at the user station 132 or through the user interface of the controller 128 .
- the user interface presented by the resonance frequency detection software 134 can have fields for receiving various parameters, including the minimum and maximum operating frequencies.
- the minimum and maximum operating frequencies can be generated by the resonance frequency detection software 134 based on various data associated with the electrical submersible pump assembly 102 .
- the electrical submersible pump assembly 102 can be associated with motor “nameplate” data, including the maximum horsepower of the motor 114 , and the motor nameplate frequency.
- the motor nameplate frequency is typically 50 Hz or 60 Hz, depending on power supply frequency.
- the HP consumption at motor nameplate frequency refers to the expected horsepower consumed by the pump 108 , gas handling device 110 (if present), and intake/gas separator 112 being run by the motor at the motor nameplate frequency.
- the HP consumption at motor nameplate frequency can be entered by a user (such as through the user station 132 ), or can be derived from other information such as pressure or flow rate information from transducers located on the electrical submersible pump assembly 102 .
- the resonance frequency detection software 134 After receiving or generating (at 202 ) the minimum and maximum operating frequencies at 102 , the resonance frequency detection software 134 causes (at 204 ) the controller 128 to control the variable speed drive system 130 to run the electrical submersible pump assembly 102 from the minimum operating frequency to the maximum operating frequency. During this frequency sweep, the resonance frequency detection software 134 receives (at 206 ) vibration data from a sensor.
- the vibration data is stored (at 208 ) and correlated to the operating frequencies.
- the vibration data and corresponding operating frequencies can be stored in a table format.

- the controller 128 based on the resonance frequency determined by the resonance frequency detection software 134 , sets (at 214 ) the variable speed drive system 130 to skip the resonance frequency.
- the variable speed drive system 130 can be associated with a jump frequency or jump frequencies that is or are to be skipped over during operation.
- control module refers to hardware, software, or a combination thereof.
