Piezometer

Ideally utilised in wells where little to no flow is expected and wellbore environments are below 250°C.

An industry standard Reservoir Group Oil & Gas Piezometer is a steadfast design to acquire pressure temperature data in high temperature conditions. A cost effective alternative to standard gauges, it is ideally utilised in wells where little to no flow is expected and wellbore environments are below 250°C. This gauge should not be used when significant vibration or electronic noise is prevalent.

This design utilises our locally produced 0.125” Downhole Instrument Cable as well as Reservoir Group’s integrated surface electronics package which provides data storage and transmission. This gauge can be installed to depths of up to 6000 meters and is typically deployed on production tubing or cemented in casing. Additionally, Omega Well can deploy this gauge in a suspended method by utilising our Downhole Instrument Cable.
