Manual dips are features that have been identified and picked interactively from a dipmeter or borehole image. The advantage of the manual dip picking over automated dip processing is that each feature may then be classified into a geological category (e.g. bedding, fractures and faults), and that only the results in which the interpreter has confidence are used for further interpretation. Another advantage of manual dip picking is the ability to measure and orient discordant and steep surfaces such as fractures and faults, which are unlikely to be identified by standard interval correlation techniques.
