Reservoir Group’s Sentinel gauge is an extremely rugged downhole pressure and temperature gauge designed to be run as part of any wireline string.

A true user-friendly ‘Run-it-yourself’ gauge contained in a bespoke spring mounted shock absorbing assembly, the Sentinel is fully automatic and requires no operator input to acquire data. The Sentinel is supplied in monitor mode, a non-recording mode, where it is checking pressure and temperature readings every two minutes. When a user-programmed temperature or pressure threshold has been exceeded, the Sentinel automatically enters record mode and stores data to memory at a pre-set sample rate. At the end of a survey, the Sentinel stops recording automatically when pressure and temperature readings fall below the user-programmed threshold values. The Sentinel then reverts to monitor mode ready for the next survey.
