Real-time production optimization of oil and gas production systems: A technology survey

This is a noncritical survey of key literature in the field of real-time production optimization of oil and gas production. The information flow used for optimization of the system is described. The elements in this description include data acquisition, data storage, processing facility model updating, well model updating, reservoir model updating, production planning, reservoir planning, and strategic planning. Methods for well prioritization, gas lift optimization, gas or water injection optimization, and model updating are discussed in the view of the information flow described. Challenges of real-time production optimization are also discussed.
