Abstract
A compter-based log processing system is described herein for exploring a subsurface formation and that uses log signals and dip signals. The system includes signal processing circuitry for storing each signal as a value individually within a universally formatted relational data base, for identifying any portions of the log signal and the dip signal that are unacceptable, and means for replacing the identified unacceptable portions of either signal with a corresponding acceptable portion from the other signal. Further, the system has the capability of processing dipmeter data, as well as log data, utilizing conventional log processing editing, plotting, and analysis programs on a single system.
