Fundamentals of Wellbore Flow

10:36 Hours
Fundamentals of Wellbore Flow is a training course designed to provide a solid foundational understanding of wellbore flow dynamics relevant to production optimization and monitoring. The course addresses both single-phase and multiphase flow conditions in wellbores, covering flow behavior through pipes and restrictions. Learners will explore methods to estimate bottomhole flowing pressure from surface measurements, especially when direct downhole gauges are unavailable. The curriculum involves practical examples, exercises, and tests that help participants apply inflow performance relationships for reservoir performance prediction. It also discusses production engineering roles from field development to production maintenance and improvement in hydrocarbon recovery.
