AUTOMATED LOG QUALITY CONTROL BY USING CATGEOKU SOFTWARE

Here are the automatic features you get after uploading LAS data:

• Interactive Visualization: The application displays three interactive plots: a Log Plot showing the curve vs. depth with color-coded badhole zones, a Distribution Histogram to check data spread, and a Box Plot to identify statistical outliers.

• Statistical Analysis: A summary table provides key descriptive statistics for the selected curve, including mean, median, standard deviation, and min/max values.

• Customizable Badhole Detection: The program automatically flags bad data using Caliper-Bit Size differences, Casing locations, and DRHO values. All detection thresholds are fully adjustable by the user for precise quality control.

• Data Cleaning & Repair: Users can instantly act on flagged data with one-click tools to delete bad points, interpolate gaps using a spline algorithm, remove negative values, or restore the data to its original state at any time.

• LAS File Export: After processing, the cleaned and conditioned log data can be downloaded as a new, correctly formatted .LAS file, ready for further analysis.
