3. Well Log Data Analysis and Machine Learning

Noise filtering and data conditioning
Remove noise in log data through noise filtering and de-spiking.
Elastic modulus calculator
Calculate 12 elastic modulus log curves from Vp, Vs, and density logs, for single or a group of wells. Flexible log calculator can derive user defined log curves.
Data Analysis
Remove noise in log data through noise filtering and de-spiking.
2-D and 3-D cross plotting
  • Flexible to select any well logs to cross plot in 2-D and 3-D, color coded by any well log
  • Samples in user defined polygons on cross plots can be updated in well sections in real-time
Predict missing logs
  • Build deep learning models to predict missing logs from other logs
  • Performance analysis of the prediction model to avoid over-training
Log facies classification
Four methods are implemented for generating facies logs:
  • Deterministic rules from one or multiple log curves
  • Self-organizing map from one or multiple logs
  • Supervised classification based deep-learning model
  • Bayes model
