Abstract: Strata surfaces can be identified in well logs and correlated across the well logs taking into account manual corrections. For example, a computing device can receive well logs. The computing device can determine multiple stratum-surface correlations based on the well logs. Then, the computing device can receive user input indicating a correction to a particular stratum-surface correlation. Based on the correction to the particular stratum-surface correlation, the computing device can update some or all of the other stratum-surface correlations.

Abstract: Well logs can be automatically correlated using dynamic warping with descriptors. For example, a computing device can receive user input indicating a manual correlation between a first node in a first well-log and a second node in a second well-log. The computing device can use the manual correlation to automatically determine a combination of descriptors usable to correlate the first node to the second node. The computing device can then perform dynamic warping on other well logs using the combination of descriptors determined by using the first well log and the second well log. This may provide more accurate correlations between well logs.
