Machine Learning Applications in Upstream

Due to complexity and scale, managing and engineering a modern hydrocarbon asset is extremely challenging. Bringing necessary data from multiple different sources and analyzing it in a relatively short period of time to provide actionable insight to field operators’ is the key to optimize performance. Supervised machine learning methods can provide effective tools for predicting uplift from operational decisions. Proper choice of features, novel use of available data and evaluation of several machine learning technologies enabled the development of an efficient and robust mechanism for identifying and prioritizing operational actions to achieve production uplift. We trained time-progressive predictive models using historical well test rates as targets and well operating conditions as features. These models were then integrated into an existing rule based production optimization recommender system to provide the uplift estimates for every recommendation, hence optimize and prioritize operating strategies.
