→Dipmeter data acquisition
For the results to be geographically significant, it is necessary to define the orientation of the tool in space. This involves continuous measurements of the orientation of the electrode array relative to north, its rotation relative to the high side of the hole, and the inclination of the tool axis from vertical. Such navigation data are produced from the output of an assembly of three orthogonally mounted magnetometers and a similar array of accelerometers. [[:file:dipmeters_fig1.png|Figure 1]] is a sketch of a four-arm tool illustrating the orientation measurements. [[:file:dipmeters_fig2.png|Figure 2]] is an expanded scale recording of the raw dipmeter data showing the orientation curves, calipers, gamma ray, and correlation curves from a six-arm tool. Note that the curves are responding to apparent bedding features less than [[length::1 in.]] thick.
