Abstract
Passive completion optimization with fluid loss control. A completion string includes a set of well tools interconnected as a portion of the completion string, the well tools including a well screen assembly, at least one valve which controls fluid communication between an interior and exterior of the string, and two packer assemblies, each of the packer assemblies including at least one swellable seal element, and the packer assemblies longitudinally straddling the valve and the screen assembly. Another completion string includes a set of well tools interconnected as a portion of the completion string, the well tools including two packer assemblies, a well screen assembly, and the screen assembly including an inflow control device which restricts fluid flow through the screen assembly, each of the packer assemblies including a swellable seal element, and the packer assemblies longitudinally straddling the screen assembly.
