Intrinsically Safe Pressure, Temperature, & Density Measurement

Single or Multi-Point Suspended Measurement Systems for Corrosive and Non-Corrosive Chambers and Wellbores. Intrinsically Safe
Bubble Tube System
High-Temperature Downhole Pressure
Designed to accurately measure pressure in high-temperature wellbores in a reliable and cost effective way.
Bubble Tube System – High-Temp Downhole Pressure
The primary advantage of the GEO PSI Bubble Tube System is its reliability, and cost effectiveness.
The concept is very simple. An automated system controls pressurized inert gas such as nitrogen or helium which is injected down a capillary tube into a pressure chamber (the same can be done in a wellbore using pressurized fluid). This causes a purge in which case an automated solenoid valve is then closed. The reservoir pressure fights back, compressing the inert gas column in the capillary tube. A high-end piezoresistive transducer measures the compressed pressure at the surface, and the GEO PSI logger makes an accurate downhole calculation of the reservoir pressure.

Impressive Track Record
Since 2010 we have installed many bubble tube systems in the Canadian steam-assisted gravity drainage (SAGD) environment. To date, we have a perfect track record of 100% installation success.

Success Rate
Low Maintenance
Our bubble tube systems are very low maintenance. We engineer each solution so that the inert gas supply only needs recharging every 1-3 months. And in some cases, supplied natural gas can be substituted for Nitrogen or Helium.
Tried & True Technology
Bubble tube technology has been used for bottom hole pressure calculations for over 75 years. Over that time the technology has been refined, and it remains one of the most reliable and cost effective methods for measuring downhole pressure in high-temperature environments. You can find our bubble tube systems deployed in SAGD, high-temperature offshore oil fields, and many other oil and gas recovery systems around the world.
