Monitoring steam chamber development in thermal hydrocarbon recovery operations
A recently granted patent (Publication Number: US12000730B2) discloses a method for monitoring steam chamber development in a reservoir created through a thermal hydrocarbon recovery operation. The method involves drilling horizontal wellbores, deploying fiber optic cables, and using a seismic wave source to generate and receive seismic waves that pass through the reservoir. By analyzing the attenuated seismic waves received at the fiber optic cable, information about the steam chamber's location within the reservoir can be extracted and transmitted to a receiver for monitoring purposes.
The patent claims also detail variations of the method, such as using a piezoelectric source as the seismic wave source, locating the source in a vertical well, and utilizing full-waveform inversion for processing the signal. Additionally, the method can be implemented in existing observation wells as part of the thermal hydrocarbon recovery operation. By combining fiber optic technology with seismic wave analysis, this innovative method offers a reliable and efficient way to monitor steam chamber development in reservoirs, providing valuable insights for optimizing thermal hydrocarbon recovery operations.
