    摘要: A wellbore device is provided which includes a fluid passage for transferring fluid between an earth formation and a surface facility, and a body transferable from a first mode to a second mode upon contact of the body with a selected fluid. The body is arranged so as to substantially close the fluid passage upon transfer of the body from the first mode to the second mode due to contact of the body with the selected fluid.
