WELLBORE SYSTEM AND METHOD OF COMPLETING A WELLBORE

摘要

A wellbore system is provided comprising a borehole formed in an earth fo rmation (10), the borehole having a borehole section containing a volume of gravel pack particles (26) and at least one body of a swellable material (22 ). Each body of swellable material (22) is adapted to expand from an unexpan ded state to an expanded state upon contact of the swellable material with a selected fluid, wherein a flow passage (30) is present in said borehole sec tion allowing fluid' to bypass the volume of gravel pack particles when the body of swellable material is in the. unexpanded state. The body of swellabl e material is arranged to substantially close the flow passage upon expansio n of the body of swellable material to the expanded state.
