Introducing Poseidon

Advanced Water-Cut Measurement For Oil & Gas Applications



The Poseidon water-cut meter features patented optical technology that delivers unmatched accuracy and reliability across 2 and 3 phase flow conditions. Multiple sensing points profile the water distribution in the pipe thus maintaining measurement accuracy in changing flow regimes and quasi-stratified flow.

The novel optical arrangement has been designed to prevent films and blockages on the optical windows to maintain accuracy at all times. The sensor has an automated diagnostic feature to detect and alert the operator of any optical issues and with multiple sensing points there is always measurement redundancy.    

The probe form factor makes integration easy, quick and cost effective. The integrated temperature measurement allows for installation into existing thermowells reducing the barriers to entry and cost of installation.

WC Range

0-100% WC range & not affected by inversion point

GVF Range

Excellent performance in wet gas conditions from 90-99.9%


Novel design to prevent fouling with automated optical diagnostics


Measurement unaffected by salinity


Easy calibration with no PVT data required

Flow Regimes

Maintains accuracy in changing flow regimes and quasi-stratified flow

Hydrate Inhibitors

Measurement unaffected by hydrate inhibitors, solids & emulsions

Traditional water-cut meters have various limitations that range from sensitivity to GVF, salinity, the transition point, limited water-cut range, inaccuracy due to optical films, complex integration methods and challenges getting a representative sample of the fluids into their sensor. Hand sampling only gives a snapshot into the wells performance while the high cost of current water-cut meters often means measurement are made when production from multiple wells are commingled losing the granularity of individual well performance and the benefit of optimization strategies.
Poseidon has been designed to overcome the shortcomings of traditional water-cut meters by providing a cost effect solution to accurately measure water-cut in real-time. The sensor can be installed upstream or downstream of the separator to monitor individual wells, water breakthrough, well tests, or group monitoring. The deep insights produced by Ai Exploration’s system allows our customers to optimize their lift and production strategies to increase their bottom line, reduce costs and contribute to ESG policies through lower production emissions.

Customer Support

The procurement and installation of sensors and equipment in the oil field can often involve a complex chain of third party providers and service companies. This can often lead to installation and operational issues and a disconnect in customer support for the end user leading to frustration. One of AI Exploration's core values is to provide swift and accurate customer support to any company utilising our technology. We have an E-learning resource portal that customers can access to support integration and issues which is fully supported by our team.
