About Training
This 5-day course will cover successful well completion and workover practices. It is a practical oriented course designed to bridge the knowledge gap in the area well completion and workover designs and operations.
Well completion is considered to be one of the most critical practices for reservoir exploitation and management. During this process, the responsible personnel is tasked to optimally design and install a system that can deliver its full potential to optimize oil gas and production, without compromising safety and reliability.
During the field life cycle, some reservoirs undergo some physical and chemical changes. This leads to loss of revenue as the wells are no longer operating at their optimal conditions. Hence, a workover/well intervention may be required to safely and efficiently restore the wells back to production. This presents a lot of challenges due to the different reservoir fluids, various operating conditions, and different operating environments.
The course possesses the following futures:
- It is the first of its kind in the industry.
- It is loaded with practical examples, case studies, and industrial applications taken from:
- Different operating environment (land, swamp, and offshore including deep-water)
- Different well conditions: High-Pressure High-Temperature, sour gas, and sweet gas, etc.
- Tropical and arctic (temperate) climates
- It provides practical exercises, and delegates will be followed up to ensure they can handle all the calculations, without difficulties.
- Focuses on different technological innovations to optimize reservoir drilling and completion practices, to improve well productivity.
- Sustainable and responsible oil and gas field development and production amid energy transition.
- It could be designed to meet the need of the clients on specific topics of interest.
- Team learning. A group completion design project accomplishes the course. All the elements of the course will help you and your team to handle the project challenge.
- Towards the end of the course, the groups formed in the class will present their completion design project for discussions/reviews.
- Delegates are allowed to come with their projects of interest, which they could substitute for the class field project design work but must be presented for discussions/reviews
