GEOHV 125
The GEOHV 125 is a breakthrough gauge that is immune to signal noise from high-voltage cables and surface equipment.
GEOHV 125 – Downhole Gauge
The GEOHV 125 is a breakthrough downhole gauge designed to specifically address a common problem for operators of high-powered equipment or with noisy wellsites. With high-voltage surface or downhole equipment, there can often be excessive electromagnetic noise which can overwhelm downhole signals. In these instances, there is no way of getting critical downhole pressure and temperature data. Until now.
Immunity To Ambient Signal Noise
Easy-ConnectTM Cablehead
Universally Compatible
- Shockingly Clean Data
Our team has developed a gauge capable of running on our standard 4mm TEC with our industry-leading patented Easy-ConnectTM Cablehead connection that is immune to signal noise. This means that no matter the electrical environment, this gauge will be able to reliably deliver every packet of data to SCADA with full resolution and accuracy.
Technical Specifications
Complex Monitoring, Simplified
When producers have to deal with challenging completions it can at times prove too difficult to implement downhole monitoring. The number of accessories needed, troubleshooting, and expensive changes to VSDs or high-voltage cables can prove too costly to implement or justify. In these cases, operators miss out on the abundance of operational efficiencies gained through the utilization of real-time downhole pressure and temperature data.
With the GEOHV 125 the solution to this headache is turn-key, requiring no expensive troubleshooting, changes to the completion, or expensive accessories. All that’s needed to begin reliably monitoring downhole is to deploy the gauge and cable as you would any other permanent downhole gauge, and tie into the compact surface interface card.

Methods
Despite its advanced capability, this gauge can be deployed like any other permanent dowhole gauge.

Dual Temperature Measurement
The unique feature set of the GEOHV 125 includes multiple temperature measurement points. Located in different areas of the tool, yet offering the same incredible accuracy and resolution, this enables a number of temperature measurement options for the end-user depending on how the tool is deployed and connected to the completion.
When the gauge is installed so as to measure the annulus/reservoir, these points offer fantastic redundant measurement. When the gauge is connected via an internally ported carrier, the first temperature point alongside the pressure transducer will measure internal temperature, and the second point will measure external/annulus temperature.
Interface Card Capabilities
The GEOHV 125 gauge is extremely capable, packing four measurement parameters into such a small package. While every gauge comes ready to provide high-quality reservoir pressure, dual temperature, and head voltage data to surface, we have developed multiple surface solutions designed to meet the needs of every budget.
