Well Performance & Relation to Damage and Stimulation

Introduction:

The course is designed to provide a comprehensive approach to perform NODAL analysis for the production system. The participant will be guided to practice predicting the rate at which a well should be capable of producing, given reservoir and fluid properties, wellbore configuration, and flowing wellhead pressure. Identify which components of the reservoir/completion/wellbore system are restricting performance

The impact of skin on well inflow is analyzed in a descriptive review of completion operations such as perforating, sand control, and matrix acidizing. The contribution of hydraulic fractures to reservoir performance will be examined. Finally, the course examines the effect of horizontal wells in optimizing the reservoir potential. Practical worked examples are used to reinforce the theoretical content.

Targeted Groups:

Reservoir and Production Engineers
