Photon Control has released the Downhole Pressure and Temperature Sensor (DHPTS), a new product, which is designed exclusively to meet the demands of the Steam Assisted Gravity Drainage (SAGD) process that is necessary to take out the bitumen from oil sands projects.
Downhole Pressure and Temperature Sensor
The SAGD process requires substantial pressure and temperature of the steam for bitumen extraction. The pressure can be beyond 100 MPa with temperature ranging to 300°C.
The capacity of measuring these process variables precisely during production is very significant for the optimization of the SAGD process and also can decrease the overall cost of production. Because of thermally induced noise at high level and material limitations, traditional sensors are likely to malfunction.
But, the elements in this new DHPTS sensor are resistant to hydrogen and completely enclosed in a stainless steel probe. This sensor shows off a high range of temperature and pressure with an 8 or 16 channel Spectral Multiplexer. The probe is linked to the interface electronics along with optical fibers present in a stainless steel cable. The length of the cable can be up to 5000 m.
