What we do at the well
We shoot the fluid level, check the pump and read the motor. Here is what each one tells you.
Fluid level shot
We put a wireless acoustic gun on the casing valve and fire it from the truck.
How it works
The gun lets off a pulse of compressed gas down the casing. The sound goes down the annulus and echoes off each tubing collar, and then off the fluid. We count the collar echoes to get the depth to the fluid.
The gun uses compressed gas, not blanks.
What it tells you
- How much fluid is over your pump
- Your pump intake pressure
- Whether gas is coming up the annulus, and how fast
- The percent liquid in a gassy column
- Your producing bottomhole pressure
- How much more the well can make
The 5,000 psi gun covers gas-lift, flowing and high-pressure wells.
Dyno on the polished rod
This one is for rod pumped wells. The rod transducer clamps on in about 30 seconds without touching your spacing.
What we get
We see the surface card and the pump card live at the well, and we run the valve checks. We can record the fluid level and the dyno together.
On crooked holes and heavy oil we use a horseshoe load cell.
What the card shows
- Tagging
- Gas lock
- Gas interference
- Fluid pound
- A leaking traveling or standing valve
- A worn pump
- A bad tubing anchor
- A possible rod part
Motor and balance
A power probe clamps on the motor leads. We don't move any wires.
- How hard the motor is working
- How much torque is on the gearbox
- How far to move the counterweights
ESP wells
On an ESP we shoot the casing the same way. That gives us the fluid over the pump intake and your intake pressure, without a downhole gauge.
There is no dyno on an ESP. It has no polished rod.
What's in your report
The readings off our tech's ticket:
- Fluid level
- Pump depth
- Casing and tubing pressure
- Submergence
- Findings
- Recommendations
You also get the shot and card files, and a PDF of the test.
Your readings are in your login as soon as our hand sends the ticket from location. The shot and card files follow as soon as he has signal.
Every test on that well stays in your login, back to the first one.
The gear
Everything talks to a base station in the truck. No cables across your location.
Wireless acoustic gun
Goes on the casing valve. We fire it from the truck, up to about 400 feet back, so our hand isn't standing at the wellhead while it records.
5,000 psi gun
For gas-lift, flowing and high-pressure wells.
Base station
Sits in the truck and links every sensor, so the fluid level, dyno, power and pressure readings are recorded together.
Rod transducer
Clamps on the polished rod in about 30 seconds. It doesn't touch your spacing.
Horseshoe load cell
For crooked holes and heavy oil.
Power probe
Clamps on the motor leads. We don't move any wires.
Dyno class
Once a month we run a free class on reading a dyno card. It is in person, with six seats and real cards off real wells. Echo Testing customers get first call on the seats.
