of 
Dipmeter
Data to Structurally Complex Areas in the Mid-Continent
EHINGER, ROBERT F.
Dipmeter tools provide
a practical method to determine the true strike and dip of strata within
a single borehole. In a vertical borehole structural dips have to approach
20 degrees before they are recognized by stratigraphic expansion. If the
borehole deviates in an updip direction, then the dips can approach 30
degrees before they produce observable stratigraphic expansion. By using
dipmeter calculations with a reducing copy machine, expanded stratigraphic
intervals can be corrected to a normal section even when the dips exceed
60 degrees. The corrected intervals can aid in stratigraphic correlations,
identify fault blocks, and quantify the internal geometry of complex folds.
"Stick plots" which can be generated from dipmeter data integrate effectively
with other subsurface tools especially seismic data. Various examples of
dipmeter
applications, types of data output, and factors that influence
data quality will be presented. Even though dipmeters for the Mid-Continent
area have been available for almost fifty years, they are still under utilized
on many exploration projects.
