Apparent dip

The orientation of any line, excluding the line of steepest descent, that can be drawn on a plane. Within image and dipmeter analysis it is sometimes necessary to present data as apparent dips relative to the borehole to allow corrections to be applied when modelling resistivity curve responses that are a part function of apparent dip.

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.
