12 Questions
What are some objectives that need to be satisfied in the design and completion of production and injection wells?
Provision of optimum production/injection performance, ensure safety, maximize integrity and reliability, minimize total costs per unit volume of fluid produced or injected
What is the purpose of producing a conceptual design or a series of alternatives in the completion process?
To select one or more designs for more detailed development
What is the goal of the detailed design process in completion string design?
To specify all components and assess sensitivity of well and completion performance to variations in reservoir data
Why is it important to minimize the total costs per unit volume of fluid produced or injected in completion design?
To minimize costs of initial completion, maintaining production, and remedial measures
What may be required in the completion design to control sand production?
Other criteria to control sand production
Why are drilling and completion operations considered crucial in the long term viability of wells?
They are crucial in meeting specified objectives and ensuring the wells can be depleted efficiently
What are the four principal decision areas in the fundamental design of a completion?
- Specification of the bottom-hole completion technique; 2. Selection of the production conduit; 3. Assessment of completion string facilities; 4. Evaluation of well performance/productivity-injectivity.
Why are a number of alternative designs for well completions selected and retained as a contingency?
Due to considerable uncertainty in the validity and accuracy of data from exploration wells.
What are the objectives in the detailed design phase of completion?
- Specify all equipment and materials; 2. Optimise completion performance; 3. Optimise well performance.
Why is an interactive approach adopted in both the conceptual and detailed design stages of completion?
Due to the diversity of design data and the range of disciplines involved in the decision-making process.
What are the three alternative approaches for the completion of the reservoir zone?
- Open hole completion; 2. Pre-drilled / pre-slotted liner or screen completion (uncemented); 3. Casing or liner with annular cementation and subsequent perforation.
What is the simplest approach to bottom-hole completion?
Open hole completion.
