OIL & GAS SPECTRAL RESISTIVITY EXAMPLE

WinLoG Oil Spectral Resistivity Example

Integrated deep and shallow resistivity, spectral gamma ray, caliper, lithology, formations and core recovery.

This example demonstrates a 180 ft borehole combining deep and shallow resistivity with caliper, total gamma ray, potassium, thorium and uranium. The geophysical curves are aligned with 23 lithology intervals, formation and member columns, core numbers and recovery bars.

Each of the seven continuous datasets contains 392 samples. The geological record includes four formations, six members and 14 recovery samples. Automated validation passes with 100% completeness, Good quality, 85% confidence, and no errors or warnings.

  • Validation reporting

Integrated Electrical and Spectral Interpretation

The log places deep and shallow resistivity beside lithology and spectral gamma-ray components. Differences between the two resistivity responses can be reviewed against borehole diameter, rock type, stratigraphic boundaries and potassium, thorium and uranium variation.

The supplied validation report records Passed status, 100% completeness, Good quality, an 85% confidence score, and zero errors and zero warnings.
