Purpose of Dyno

  • Function test basic motor anatomy
  • Build a realistic power curve based on actual performance
  • Provide a consistent motor to field
  • Simulating well bore conditions to test motor reliability
  • Provide data to make more informed drilling parameter decisions
  • Track and manage Power section performance
  • Look at power output of different motor configurations

VON Dynamics Dyno Capabilities

  • 9 5/8” to 3 ½” tools
  • Up to 4° bent housings
  • Motor bend is on its side (reduce vibration)
  • Up to 75,000 WOB (bearing load)
  • 3000 gallon tank (water only)
  • Purge Filter box for post run test
  • Heat exchanger for duration testing
  • 30,000ft lbs of torque
  • 920 GPM @ 1600 psi

VON Dyno Standard Motor Test

  • Motor’s bend angle is measured (+/- 0.1°)
  • Loaded into dyno and flow for 2 minutes @ 60% of test flow rate
  • Temperature readings are measured and recorded 3 times at the bearing housing and power section during this time.
  • Motor is brought to test parameters and the power curve is built automatically over a 1 – 5 minute period of time.
  • Data is compiled and motor efficiency is recorded.

Operator Specific Assumptions

  • A 5 rig program sending 50 motors per month to location
  • 50 motors can result in 7 failures per month using multiple backups or 11 failures assuming every motor is used
  • Assuming each motor failure costs at least 6.5 hours of rig time, this translates into a potential impact of $20,000 per motor incident resulting in a trip.

Motor Optimization

Drilling motors are an essential component in any downhole drilling application. During the drilling process, a “good” motor operating at optimum performance can increase ROP significantly. Conversely, a motor that is operating at less than optimum output can have the adverse effect. By the nature of their design, drilling motors create dynamic forces that both assist in the drilling operation, and, at times cause damage to other components of the drill string.

In most cases, each motor sent to a location is almost always accompanied by at least one motor of the same size and configuration. Rarely, even if the motor is new, will it operate identically to it’s back up

VON Dynamics process of testing drilling motors on our dynamometer, identifying the operating characteristics of each motor, and “grading” them based on horsepower, torque, differential and vibration will assure that the “best” motor is put in the hole first.

  • Identify motors that are using mechanical energy more effective than others
  • Creation of a grading system for Pass / Fail criteria
  • Establish actual maximum outputs, operating parameters, and efficiencies vs relying on published data that is based on conservative approximations
  • Allows us to make more informed decisions on which motor to use as a primary and which could be selected as a backup or quarantined

Motor Optimization

The data analysis gathered during this testing will also identify the optimum operating horsepower and flow allowing the driller to get the most out of the motor while downhole.

Equally as important, dynamically testing a motor before putting it in the hole can identify motors that are not operating within the design parameters eliminating unnecessary tripping time, poor ROP and potential lost or severely damaged BHA’s.

Our system of “grading” each motor will help assure that the best tool is sent downhole first, operate at optimum performance increasing ROP and reduce or eliminate costly downtime.

Shock Mitigation

  • Vibrations has been a well known issue for MWD reliability
  • Often times there is no indication of where vibration comes from
  • Von recently fitted the Dyno system with a Vibration sensor that now records G shock while testing motors
  • As tests are done, we are able to identify specific motors prodicing excessive vibration that could harm other drill string components.
