OIL & GAS CHROMATOGRAPH EXAMPLE

WinLoG Oil Chromatography Example

Integrated C1–C5 gas chromatography, gamma API, drilling rate, fluorescence, oil shows, cuttings and lithology.

This example demonstrates a petroleum well log covering the 5,000–6,000 ft interval. Five chromatograph curves—C1 through C5—are presented beside drilling rate, gamma API, cuttings fluorescence, direct fluorescence, oil-show symbols, percent cuttings and detailed lithologic descriptions.

The record contains 501 samples for each continuous curve, 12 lithology intervals, 16 cuttings intervals and nine oil-show records. Automated validation passes the example with 100% completeness, Good quality, 85% confidence, and no errors or warnings.

Integrated Gas and Geological Interpretation

The combined display allows changes in light hydrocarbon components to be compared directly with gamma response, drilling behaviour, fluorescence, oil shows and cuttings composition. This makes the example useful for illustrating how multiple mud-logging datasets can be synchronized within one professional well-log presentation.

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