HOUSTON – Petrobras has taken delivery of READ’s new PerForM permanent reservoir monitoring system following a final acceptance test. The equipment is going to Brazil for ultimate installation downhole in the Namorado oilfield in the second half of this year.
Following installation, READ plans a 4D seismic survey and the system will provide continuous real-time micro-seismic monitoring of the reservoir.
The system can have as many as 120 levels of seismic sensor nodes downhole and can include pressure, temperature, and other measurements on a high-speed data link to the surface. Placing the sensors in the annulus allows for real-time data acquisition without interruption of well production. When the micro-seismic monitoring is combined with real time multiple migrations, PerForM offers a combination to image of large reservoir areas, says READ. PerForM also enhances well safety by providing early indication of reservoir leakages, gas accumulations, and seabed subsidence.
