Upper & Lower Completion Design
This course covers upper and lower completion design as an integrated system. Participants study design basis and architecture, lower completion options including sand control and inflow control, interface equipment and crossovers, upper completion tubing and equipment, isolation and barrier requirements, installation sequence, intervention access and the interaction between the two halves.
Description
Most completions are built in two parts. The lower completion connects the reservoir to the well, through screens, gravel packs, perforated liners or open hole, and is usually installed first. The upper completion carries the produced fluid to surface, with tubing, packer, safety valve and flow control equipment, and is installed afterwards and can be retrieved for workover.
This course covers both and the interface between them. It starts with design basis and completion architecture, then covers lower completion options, including open hole, cased and perforated, screens, gravel packs and inflow control, and the zonal isolation they require. It covers the interface: polished bore receptacles, seal assemblies, crossovers and the clearances that constrain everything above. It then covers upper completion design, including tubing sizing and stress analysis, packers, safety valves and flow control, barrier requirements, the installation sequence for both halves, intervention and workover access, and the consequences of design decisions in one half for the other.
The interface is where completion designs fail. A lower completion installed with a seal bore of a given size fixes the maximum size of everything run through it afterwards, and a seal assembly that does not stab cleanly or a crossover that restricts flow becomes a permanent limitation. Designing the two halves together avoids finding this out during installation.
Retrievability is the reason for the split. The upper completion can be pulled for workover without disturbing the sand control or the reservoir connection, which protects the most difficult and expensive part of the completion. That benefit only exists if the interface is designed to allow clean retrieval and re-entry.
Barriers have to work through both halves. During installation, after installation and during any intervention, the well needs two verified barriers, and the equipment that provides them sits in both the lower and upper completion. Mapping those barriers through each stage of the installation sequence is part of the design rather than a safety case written afterwards.
By the end of this training, participants will be able to:
- Define the completion design basis and select the completion architecture.
- Select lower completion options for the reservoir and well conditions.
- Design zonal isolation within the lower completion.
- Specify the interface equipment between lower and upper completions.
- Size tubing and perform stress analysis for the upper completion.
- Select packers, safety valves and flow control equipment.
- Map barriers through installation, production and intervention.
- Plan the installation sequence for both completion halves.
- Design for intervention and workover access.
- Assess how design choices in one half constrain the other.
The course is instructor-led. Participants design complete two-part completions for given wells, working from reservoir requirements through lower completion selection to upper completion design and installation sequencing. Field cases cover interface failures and completions that could not be retrieved. Participants are encouraged to bring their own designs for discussion.
