Well logging has substantially contributed to the evaluation of these two quantities. The reserves of a particular geological structure are additionally controlled by the geome

Dips are measured with respect to the borehole (“apparent dips”) or with respect to geographic north and the earth’s vertical at a given location (“true dips”).
