Manual dips

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.

About the glossary
This listing is not exhaustive or definitive, do not expect Oxford English Dictionary standards; it is aimed at those who need to understand basic principles and those that read reports on dipmeters and borehole images requiring some technical help to get the most from such documents.

We have attempted to make the descriptions and explanations generic, giving the glossary a wide application and appeal, with minimal, if any, commercial bias. If you spot any mistakes, omissions or any problems with the explanations, please do not hesitate to contact us, and we will try to accommodate your comments.
