Wood Group Production Technologyhe industry, the PDRC (Casing Conveyed) System is installed on the outside of the production casing in custom engineered housings. Communication to the wellbore and/or the reservoir is provided through unique pressure ports.

Continuous measurements can be obtained throughout the life of a well without any impact or interference with wellbore operations such as pump changes, stimulations, workovers, etc. Using the PDRC system, pressure data starts with cementing operations, carries on through underbalance drilling and remains in place for long term production optimisation and reservoir analysis. Multiple sensors are installed with each PDRC system, affording redundancy and reliability in each instrumentation system.

Typical Applications:
Production optimisation
Transient well testing
Observation wells
Limited wellbore annular space
Zonal interference testing
Monitoring cementing pressures
Underbalanced drilling
EOR applications:
SAGD and SWAGD
vapex
methane injection
CO2 flood
Pump control production optimisation
Hydraulic fracturing
Injection monitoring

Features and Benefits
Monitoring of pressures both inside and external to the production casing
No downhole electronics to fail
No downhole batteries to go dead
Real-time bottomhole pressure and temperature
Simple wellbore exit bushing
Eliminates ongoing costs on memory gauges
Flexible data acquisition
