SYSTEM AND METHOD FOR PREDICTING THE FRONT ARRIVAL TIME IN RESERVOIR SEISMIC MONITORING |
摘要 |
A system and method for predicting the front arrival time in seismic monitoring is disclosed The method includes measuring or computing a physical property reference signature at a calibration point, the physical property reference signature based on a change in a physical property over time due to a well injection; computing a seismic attribute reference signature at the calibration point based on the physical property reference signature; identifying a reference marker, the reference marker corresponding to a change in the seismic attribute reference signature at the calibration point over time; detecting a measured marker, the measured marker corresponding to a change in a seismic attribute of a recorded dataset over time; calibrating the measured marker; and calculating a marker arrival time for a location other than the calibration point. |

1. A method for predicting the front arrival time in seismic monitoring, comprising:
measuring or computing a physical property reference signature at a calibration point, the physical property reference signature based on a change in a physical property over time due to a well injection; computing a seismic attribute reference signature at the calibration point based on the physical property reference signature; identifying a reference marker, the reference marker corresponding to a change in the seismic attribute reference signature at the calibration point over time; detecting a measured marker, the measured marker corresponding to a change in a seismic attribute of a recorded dataset over time; calibrating the measured marker; and calculating a marker arrival time for a location other than the calibration point. |
