Correlating Geological and Seismic Data with Unconventional Resource Production Curves using Machine Learning

Abstract

We present a machine learning workflow that incorporates geophysical (seismic attributes) and geological data, as well as engineering completion parameters, into a model for predicting well production curves. The study area is in southwest Texas in the lower Eagle Ford formation. We make use of functional principal component analysis to summarize the well production time series, and random forest models to predict the functional principal components with geological, geophysical and engineering data as predictors. We are then able to predict the well production time series, with 65-76% accuracy. This method incorporates disparate data types into a robust, predictive model that predicts well production in unconventional resources.
