Name: Rubber-banding of logs
Goal: Convey TVD uncertainty in logging depth.
Description: A set of MWD logs is to be compared to wireline logs. The MWD and Wireline log sets were measured with a different depth measurement systems, each subjected to independent stretch errors. One of the measured depths has to be stretched or shrunk by matching similar features across the MWD and wireline logs.Example from Dashevskiy et al., 2008, Dynamic Depth Correction to Reduce Depth Uncertainty and to Improve MWD/LWD Log Quality, SPE Drilling and Completions, page 13-22
