GEO4-20 CP 105 T – Permanent Downhole Gauge

The GEO4-20 CP 105 T is a specialty solution which was designed for measuring real-time pump intake pressure in ESP wells which suffer from electrolytic and galvanic corrosion.

Downhole electrolytic corrosion is caused by a current from an external source. It could be from the AC power for an ESP pump, or any number of issues associated with improper grounding or electrical connections. Downhole galvanic corrosion is caused by an electric current generated by two different metals in a conducting medium such as seawater. Both of these forms of corrosion have similar effects, and can cause system failures at an alarming rate.

This specialty gauge has been engineered to reverse traditional electric flow through the gauge which counteracts the effects of electrolytic corrosion. This, along with the inclusion of a sacrificial anode, prevents damage to downhole equipment from the effects of galvanic corrosion which is common in salt water wells.
