ABSTRACT

The physics of induction well-logging measurements controls the fundamental vertical resolution of a well log. Logs with great depth of investigation have coarser vertical resolution than the logs of smaller depth of investigation where measured by the same physical principles. For log-interpretation purposes, however, it is often convenient to have all logs at the same vertical resolution. The resolution matching technique essentially extracts high-resolution variations from a high-resolution curve and imposes them onto the low-resolution curve, to enhance the lower-resolution curve to the same resolution.
