Intermediate String Design Enhances Intelligent Deepwater Completions
This paper describes an intelligent completion design installed in two deepwater wells with dual-zone stack-pack sand-control lower completions and the installation of an intermediate string to isolate the reservoir in each zone.
An intelligent completion design was installed in two wells in China’s L field deepwater project. Both wells have dual-zone stack-pack sand-control lower completions. To handle critical well-control concerns and enable production from each zone, an intermediate string was installed to isolate the reservoir in each zone temporarily. While the complete paper details both the completion string design and its field installation, this synopsis concentrates on the former aspect of the project.
