Abstract: System and methods for transforming well production data for predictive modeling are provided. Aggregated production data for one or more wells in a hydrocarbon producing field is pre-processed in order to generate clusters of the production data, based on a set of uncontrollable production variables identified for the wells. The pre-processed production data within each of the clusters is standardized based on clustering parameters calculated for each cluster. The standardized production data within each of the clusters is then used to generate transactional data for use in a predictive model for estimating future production from the one or more wells.
