SYSTEM AND METHOD FOR INTER-WELLBORE MONITORING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17935475 titled 'SYSTEM AND METHOD FOR INTER-WELLBORE MONITORING
Simplified Explanation
The method described in the patent application involves using seismic data obtained from optical fibers in two different wellbores to create a virtual seismic dataset for an inter-wellbore region of interest. This virtual dataset is then used to determine a seismic velocity model for the region through seismic inversion.
- Seismic data is collected from two different wellbores using optical fibers.
- Seismic interferometry is applied to the collected data to create a virtual seismic dataset.
- Seismic inversion is then used to determine a seismic velocity model for the inter-wellbore region of interest.
Potential Applications
The technology described in the patent application could be applied in various industries such as oil and gas exploration, geothermal energy exploration, and underground storage monitoring.
Problems Solved
This technology helps in accurately determining seismic velocity models for inter-wellbore regions, which is crucial for understanding subsurface structures and making informed decisions in resource exploration and monitoring activities.
Benefits
The use of optical fibers in collecting seismic data provides a cost-effective and efficient way to gather information about subsurface structures. The virtual seismic dataset created through seismic interferometry allows for detailed analysis and modeling of the inter-wellbore region.

Original Abstract Submitted
Systems and methods are disclosed. The method includes obtaining a first seismic dataset generated by a passive seismic source at a first epoch for an inter-wellbore region of interest lying between a first wellbore and a second wellbore. The first seismic dataset includes a first plurality of seismic traces recorded by a first optical fiber in the first wellbore and a second plurality of seismic traces recorded by a second optical fiber in the second wellbore. The method further includes determining a first virtual seismic dataset by applying seismic interferometry to the first seismic dataset. The method still further includes determining a first seismic velocity model for the inter-wellbore region of interest by applying seismic inversion to the first virtual seismic dataset.
