SYSTEM AND METHOD FOR SUBSURFACE RESERVOIR CHARACTERIZATION |
摘要 |
<p>A system and computer-implemented method for characterizing a subsurface reservoir is presented. The method includes receiving seismic data and at least one migration velocity model representative of the subsurface reservoir and well logs representative of a geologic region similar to the subsurface reservoir; analyzing the well logs to determine regional trends that differentiate at least two of porous sands, cemented sands, and shales; inverting the seismic data to obtain a p-impedance model and an s-impedance model; predicting a gross sand volume from a ratio of the p-impedance to the s-impedance; and determining a porous sand volume from the gross sand volume through a depth dependent cutoff for cemented sand p-impedance values.</p> |
