A method of predicting hydrocarbon production from one or more artificial lift wells is disclosed. Measurements and/or well test data are obtained from one or more artificial lift wells representing well performance at more than one time period. A statistical model, representing well performance, is generated. Using the statistical model and the measurements and/or well test data, real-time production of the one or more artificial lift wells is predicted and a measure of confidence is generated. Potential optimization opportunities are identified for well performance based on the predicted real-time production of the one or more artificial lift wells. The optimization opportunities are outputted. Hydrocarbon production activities are modified using the optimization opportunities.

Method and system of producing hydrocarbons using physics-based data-driven inferred production

A method and system are described for hydrocarbon exploration, development and production. The method relates to performing regression and/or classification in subsurface models to support decision making for hydrocarbon operations. The evaluation may then be used in performing hydrocarbon operations, such as hydrocarbon exploration, hydrocarbon development and/or hydrocarbon production.

Methods and apparatus for measuring individual phase fractions and phase flow rates in a multiphase flow based on velocity of the flow, speed of sound through the fluid mixture, and the density of the fluid mixture. Techniques presented herein are based on measuring frictional pressure drop across a flowmeter conduit, determining a surface roughness term for the conduit during initial flow tests or through other mechanical means, implementing a correction method to balance the momentum equation, and calculating the fluid mixture density using the measured pressure drop. The techniques may be applicable to measuring flow parameters in horizontally oriented conduits and, more generally, conduits of any orientation.
