A dip log. 

(1) A well log from which formation [[dip]] magnitude and [[azimuth]] can be determined. The [[resistivity]] dipmeter includes three or four (sometimes eight) micro-resistivity [[reading|readings]] made using sensors distributed in azimuth about the logging [[sonde]] and a measurement of the azimuth of one of these; a measurement of the hole [[deviation]] or [[drift angle]] and its bearing; and one or two [[caliper]] measurements. The azimuth, deviation, and [[relative bearing]] are measured by a system similar to that described for the [[poteclinometer]]. The microresistivity [[curve|curves]] are correlated to determine the difference in depth of bedding markers on different sides of the hole. See also [[high-resolution dipmeter]] and [[poteclinometer]].

(2) Other types of dipmeters use three [[SP]] curves, three wall scratchers, etc. to produce logs.

(3) A log showing the formation dips calculated from the above, such as a [[tadpole plot]] or [[stick plot]]. See illustration of dip patterns at [[dip]].
