-The gauge can be used on propellant jobs, and ANY type of perforating work.

-Tool design or improvement.

-Failure analysis of other Tools.


-Verify the actual propellant or perforating burn pressure profile

- Did it burn properly or did it go “Low Order”?

- Was there enough propellant to do the job?

- If the job was not successful, you can use the actual pressure data, collected from the gauge, to design a BETTER job the next time…

-Measure the pressure and temperature after the fracturing or propellant job

-Determine the actual fracturing response of the formation


-Record hydraulic fracturing and stimulation jobs

-Record tool movement and impact/vibration, using the Gauge’s accelerometers

◦ - Use to analyze tool failures

◦ - Design better tools

- Use pressure data to measure reservoir properties and determine “Frac Closure Pressure”

- Use the “gauge” to fire the StimGun™ Assembly, StimTube ™, or other

perforating tools

- Collect the Pressure / Temperature / Low and High G Acceleration profiles

- Leave the gauge in place to record pressure/ temperature changes AFTER the gun fires

- Fish the Gauge out and download the data

- Determine if the tool fired correctly

- Use with propellant or perforating tools

DROP BAR WARNINGS….

◦ If the DROP BAR Gauge is dropping through AIR (no fluid), you can NEVERhave a change in the “Restriction ID”. If you do, you can damage the gauge hardware or batteries, and not collect any pressure data

◦ IF you have a change in the ID restriction in your pipe, be sure it ONLY occurs in FLUID!

◦ Please let Scott Ager ([email protected]) review your well diagram for your drop bar application, before your job. Indicate the well depth where the top of the fluid column starts.
