SYSTEMS AND METHODS FOR ALIGNING A MONITOR SEISMIC SURVEY WITH A BASELINE SEISMIC SURVEY

摘要

Systems, methods, and mediums may implement obtaining baseline traces of a baseline seismic survey and monitor traces of a monitor seismic survey; employing a computer to align the monitor traces to corresponding baseline traces using an error function having a phase-based component, thereby obtaining an aligned monitor survey; generating with the computer a comparison of the aligned monitor survey to the baseline seismic survey; and using the comparison of the aligned monitor survey to the baseline seismic survey to determine a change in the subterranean hydrocarbon producing reservoir.

1. A seismic monitoring method for determining a change in a subterranean hydrocarbon producing reservoir, comprising:
a. obtaining baseline traces of a baseline seismic survey during a first time period and monitor traces of a monitor seismic survey during a second time period, the baseline seismic survey and the monitor seismic survey representative of the subterranean hydrocarbon producing reservoir; b. employing a computer to align the monitor traces to corresponding baseline traces using an error function having a phase-based component, thereby obtaining an aligned monitor survey; c. generating with the computer a comparison of the aligned monitor survey to the baseline seismic survey; and d. using the comparison of the aligned monitor survey to the baseline seismic survey to determine a change in the subterranean hydrocarbon producing reservoir.
