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 saltwater wells.

Technical Specifications

Product Development Background

The GEO4-20 CP 105 T 4 20mA pressure gauge was designed to maximize reliability, cost-effectiveness, and to be easy to install and integrate into a highly corrosive downhole system.

It is engineered to connect to metal armoured cables (TEC) via metal-to-metal sealing techniques. Our innovative patented Easy-ConnectTM Cablehead System reduces installation errors and improves system reliability. The gauge body is welded and requires no elastomer. Ingress protection is provided by a glass feed-through system and dialectic oil chamber.
