AES has designed a pH probe used to measure and monitor pH in the subsea environment, particularly useful in drilling operations and the prediction of cement returns. The probe, which features a handle for ease of manipulation by the ROV, monitors pH levels within a wellbore and assists in the accurate prediction of cement return. This allows for the well to be capped in a timely fashion, preventing costly damage associated with rupture.

Our pH probe is entirely self-contained and battery powered, with an extensive battery life of approximately 72 hours. The probe’s red LED display is highly visible in dark water, and features an energy-conserving sleep function that can be switched on or off by flashing an ROV’s lights. The probe also features a logging function that can record pH readings for later download and analysis.
