Predict-Beta-Function-Using-Neural-Network: Utilizes deep neural networks to predict the diagenesis Beta function, crucial for pore pressure prediction.
-
Using-ML-to-Discover-New-Physical-Model: Explores machine learning techniques to uncover new physical models for seafloor temperature estimation.
-
Lithology-Classification-Using-Deep-Neural-Network: Implements machine learning to classify lithology using seismic attributes (Vp, Density, PR) and deep neural networks for geophysical interpretation.
Rock Physics and Pore Pressure Prediction:
-
Basin-wide_rock_physics: A comprehensive project focused on basin-wide rock physics modeling using Jupyter Notebook.
-
Basin-wide-rock-physics---3D: Extends rock physics template calculations from 1D to 3D for enhanced subsurface analysis.
-
Sand-RPT-Compare-Different-Sand-Models: Compares various sand models within a rock physics template framework.
Geomechanics and Wellbore Breakout:
-
Stress-concentration-and-wellbore-breakout: Analyzes stress concentration around wellbores and the potential for breakout scenarios.
-
Stress-concentration---3D: Visualizes stress concentration around wellbores in a 3D context.
Fun Stuff and Web Apps:
-
Snap2PDF: A web app that transforms photos of documents into searchable PDFs. Built with a focus on accessibility and simplicity, Snap2PDF is perfect for organizing and digitizing your paperwork.
-
Rock Physics Templates (RPTs): A web app designed to streamline rock physics analysis by allowing users to input, visualize, and manipulate rock physics templates. The app supports dynamic column creation, formula-based calculations, normalization, and neural networks.
