COURSE OVERVIEW:

Completion Design for Cased Hole and Open Hole Wells is a high-level engineering program that focuses on the critical decision-making process of selecting the most appropriate wellbore interface for specific reservoir conditions. This course provides a detailed comparison between the structural security of cased and perforated completions and the high-productivity potential of open-hole configurations. Participants will learn to evaluate geological risks, such as formation instability and fluid contacts, to determine which design maximizes the present net value of the asset.

The scope of this training includes the engineering of sand control, zonal isolation, and flow efficiency. For cased-hole designs, the course covers the mechanics of perforating and the importance of cement bond integrity. For open-hole designs, the curriculum delves into the use of open-hole packers, swellable elastomers, and sand screens. Attendees will explore how these designs affect future interventions and the overall life cycle of the well, ensuring that the chosen completion can handle secondary recovery and stimulation needs.

Coverage also extends to the integration of advanced technologies like intelligent completions and multilateral systems. Participants will learn how to model inflow performance for both vertical and horizontal wells, accounting for the unique skin factors associated with different completion types. By the end of this course, engineers will be equipped to design completions that optimize reservoir drainage, manage water and gas breakthroughs, and maintain mechanical integrity throughout the decades of the well’s productive life.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Evaluate the technical and economic trade-offs between cased-hole and open-hole designs.
• Identify formation characteristics that dictate the need for specific completion types.
• Design cased-hole completions with an emphasis on optimal perforation strategy.
• Configure open-hole completions using standalone screens or gravel packs.
• Analyze the role of swellable packers in providing zonal isolation in open holes.
• Explain the impact of completion type on reservoir skin and productivity index.
• Select appropriate materials for corrosive and high-temperature well environments.
• Design completions for horizontal and highly deviated wellbores.
• Integrate intelligent completion sensors and valves into the well design.
• Predict the performance of multizone completions and selective injection systems.
• Assess the risks of formation collapse in open-hole environments.
• Develop a completion program that facilitates future workover requirements.
• Utilize Nodal Analysis to validate the efficiency of the chosen completion design.

TARGET AUDIENCE:

Completion Engineers, Drilling Engineers, Reservoir Engineers, and Production Managers involved in well design and field development planning.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
