GEOESP 150 Dual EV – Downhole ESP Gauge

The GEOESP 150 Dual EV Downhole Gauge is designed to be mounted below the electrical submersible pump (ESP) system bottomhole assembly with an industry-standard flange connection.  This is the first tool to incorporate our new Enhanced Vibration sensor. This technology, over time, will provide operators with a more in-depth and detailed picture of the health of their down hole assets, as well as allow for predictive health analytics to be utilized for long-term planning.

Technical Specifications

Enhanced Vibration Data

Our industry first ESP EV technology captures 512 frequencies of highly detailed enhanced vibration data. This allows for an incredibly accurate direct analysis of the downhole rotating equipment by utilizing a proven surface maintenance technology in a downhole environment. This enables predictive long-term ESP health monitoring and minimizes downtime. Additionally, this provides the added benefit of being able to forecast system failures minimizing costly reactive unplanned workovers. This highly accurate downhole data can then be used by the platform to develop Machine Learning survivability, diagnostic, and optimization analysis of your ESP and wellbore.

Pump Discharge Pressure

Utilizing a pump discharge sub and a high-quality 4mm control line made in-house at our GEO PSI headquarters, the GEOESP 150 Dual gauge provides optional pump discharge pressure measurement. This enables an even greater level of insight for operators as to the optimization and health of the overall ESP system.

3 Phase Modular ESP Choke

The GEO PSI 3 Phase Modular ESP Choke offers a unique modular design. This enables users to install the components in a variety of locations as either a complete unit, or in separate pieces. This simple modular design provides unparalleled versatility and cost savings to the end user. A lockable & weatherproof cabinet provides secure protection to internal components. And easy access to electrical connections allow for easy configuration within the transformer, and flexibility to make modifications over time.

E6 Interface Card

The E6 Interface Card is a premium downhole telemetry decoder that takes the raw signal from the downhole gauge, and converts it into usable data. When used with our ESP gauges and the corresponding surface choke the E6 Interface Card connects the downhole tool to the surface data acquisition equipment. The non-proprietary design allows the output data to be tied in to almost any traditional SCADA or other surface data acquisition setup.
