Abstract: A method for managing a fracturing operation. In one implementation, the method may include positioning one or more sources and one or more receivers near a hydrocarbon reservoir; pumping a fracturing fluid into a well bore of the hydrocarbon reservoir; performing a survey with the sources and the receivers during the fracturing operation; comparing the baseline survey to the survey performed during the fracturing operation; analyzing one or more differences between the baseline survey and the survey performed during the fracturing operation; and modifying the fracturing operation based on the differences.

Abstract: Propagation of wavefields are simulated along paths in a survey environment, where the simulated propagation includes an influence of a reflection at an interface that causes ghost data in measured survey data. Deghosting of the measured survey data is performed using the simulated wavefields.
