Well Log Editing In Support Of Detailed Seismic Studies

Modern seismic processing techniques often permit relatively detailed interpretation. Inherent in many of these detailed seismic applications is the necessity of calibrating seismic information with wellbore data. Consequently, every effort must be made to insure that wellbore data provide the best possible picture of in situ physical properties of the subsurface section. This paper discusses the need for well log editing and the fact that the editor must not only recognize bad data but must also determine the most appropriate substitution values. Three levels of editing (mechanical, interpretive and modeling) are identified and examples of each are presented.
