Flow restrictions into the wellbore create additional pressure drops (skin) and reduce well productivity. It is essential to understand the various causes of skin either those implicit in the completion design or arising from formation damage in drilling, completion and production to diagnose and remediate well productivity problems and in predicting well performance.
The objective of this course is to review how reservoir and well performance and skin are handled in various nodal analysis calculations and in turn how these are affected by various completion and well intervention methods.
The course also provides the attendees with a firm foundation for well performance modelling applied in nodal analysis software applications commonly used in the industry.
In this course you will learn:
- the basics of transient and steady state flow modelling from the reservoir into the wellbore
- the development of common inflow performance relationships and their application to oil, gas and condensate wells
- the various components of skin, their causes and how they affect well performance
- recognising and diagnosing skin
- how various completion and treatment methods cause skin and impact reservoir performance: perforating, sand control, matrix acidising
- inflow performance from hydraulically fractured and horizontal wells
Who should attend?
This course is intended for petroleum, reservoir and production engineers interested in understanding the flow of hydrocarbons from the reservoir into the wellbore and the management of skin for maximising well productivity.
