Abstract
A method for autopicking of bedding in a well includes receiving image logs associated with the well, eliminating tool marks from the image logs, performing a grid search for (1) a vertical amplitude and (2) a horizontal shift of the bedding at plural sampling depths to obtain a predicted bedding, calculating an azimuth and a dip of the predicted bedding, and generating an image of the predicted bedding, wherein the image includes structural features of the well.
Claims20
A method for autopicking of bedding in a well, the method comprising:
- receiving image logs associated with the well;
- eliminating tool marks from the image logs;
- performing a grid search for (1) a vertical amplitude and (2) a horizontal shift of the bedding at plural sampling depths to obtain a predicted bedding;
- calculating an azimuth and a dip of the predicted bedding;
- and
- generating an image of the predicted bedding, wherein the image includes structural features of the well.
A method for facies classification based on image logs associated with a log, the method comprising:
- receiving image logs associated with the well;
- splitting the image logs into plural patches;
- implementing a trained classifier to determine the facies corresponding to the plural patches;
- and
- assembling the facies to obtain an image of the well, wherein the image includes structural features of the well.
