Methods to Monitor Wear in Oil and Gas Production Tubing Without Well Intervention | InnoCentive Challenge

[Joshua Lopez]

I get regular notices on these types of proposals. Some are pretty interesting.

I believe Sensorica may be interested in providing solutions for this particular issue.

If we can find sensors to measure things like pollutants in the oil/air then we could create solutions to detect wear and tear.

Even something like a turbidity sensor could maybe help detecting pollutants in oil caused by wear and tear, but I'm guessing the pollutants could be too small to detect with a turbidity sensor.

Vaporising oil could allow gas sensors to detect pollutants caused by wear and tear.

Analysing gas is easier because there are loads of different types of cheap gas sensors which are readily available and compatible with arduinos.

Just start by defining the control levels of certain gases, then detect and alert when something changes, or when an undesirable gas is detected or goes above control levels.

Cheers,

John

Agreed. I think monitoring gas levels is the way to go. To avoid direct impact and excessive corrosion of the sensors within the tubing. A high pressure auto venting test port could be installed at multiple points along the tubing. Gas sensors within these test ports could be used to capture samples and relay results to a monitoring station.

The MQ gas sensors could be a good option:

There are different versions for different types of gases. So it's a matter of choosing the gas type you want to monitor and picking the appropriate sensor.

The big question is how to gasify/vaporise the liquids so the sensors can analyse them. A high pressure venting port might work. Worth a try.

The more I research, the more I believe the steel tubing will need to have an exterior coating/jacket made of material that will provide unique particle, chemical and or electrical readings that indicate the tubing’s wall has been compromised and it’s time to replace the tubing. The coating/jacket could be wire meshed, so when the tubing’s wall is penetrated it will short out and indicate when and possible where the tube was compromised. The coating/jacket would have to have the strength to hold rated pressure for as long as it takes to shutdown and depressurize the tubing for replacement. Something like that.
