ABERDEEN, UK – A new downhole pressure sensor capable of operation in 500 °C (932 °F) environments is being introduced. Zenith Oilfield Technology Ltd. says it plans to show test results on its XT system next month.

The extreme temperature system uses ceramic insulation to withstand the temperatures. A new pressure sensor also was developed for this application. It is a molecular bonded micromachined sensor constructed of ceramic monocrystalline silicone and Pyrex, says Zenith.

“This technology overcomes the historic problem of monitoring steamflood operations and also HP/HT wells as the gauges available have short life spans and give erroneous results,” says Greg Davie, MD of Zenith. We now have robust technology that performs at high temperatures which will ultimately improve production and reservoir drainage.”
