SYSTEM AND METHOD FOR CHARACTERIZATION WITH NON-UNIQUE SOLUTIONS OF ANISOTROPIC VELOCITIES |
摘要 |
<p>A system and method for characterizing structural uncertainty in a seismic analysis of features in a subsurface region includes obtaining seismic data including information representative of the features, performing a plurality of depth migrations on the seismic data, each depth migration being based on a model using a respective set of parameters relating to a velocity field and anisotropy of the subsurface region, selecting a family of equivalent solutions from the plurality of depth migrations, evaluating a characteristic of at least a portion of the subsurface region for each member of the family of equivalent solutions, determining a range of values of the evaluated parameters, and based on the determined range, determining a degree of uncertainty of the seismic analysis.</p> |
