Bachelor's Thesis
Title: “Vp logs prediction from well logs and seismic using ANFIS”
The goal was to infer sonic logs for 27 wells located in a productive basin in Venezuela, using fuzzy logic and neural networks combining radioactive and resistive logs different seismic attributes as input. The generated maps showed the expected low p-wave velocity behavior for most of the geologic horizons around each currently active well.
The project included OpendTect Neural Networks module, MATLAB ANFIS (Adaptative Neuro-Fuzzy Inference System) for training the fuzzy sets, SegyMat library for reading traces, and Petrel, Oasis Montaj for data management.
Applications in Physical Geography and Earth Sciences

Project: Horizon Angles (ArcGIS Toolbox)
I developed a script that calculates the maximum angular obstruction for each cell on a raster, specially from a digital elevation model, recreating functions from GRASS GIS and GDAL. The project required the design of a graphic interface (GUI) letting the user parse parameters between ArcGIS and Python. (Available on Github)
Project: The prospects of coffee cultivation in South America in a future climate
I developed group of Python scripts for classifying The Earth's climate zones based on Köppen-Gauger method, averaging NC files in climate normals for global temperature and precipitation from several CMIP6 experiments: historical and Representative Concentration Pathway 8.5(RCP) models. Available on Github.
