Method and apparatus for providing controlled force transference to a wellbore tool

摘要

Method and apparatus for actuating one or more downhole well tools carried by a production or workstring conduit having an imperforate wall and for blocking fluid communication between an activating fluid body and a second fluid source within said well across dynamic seals between actuating members of the well tool, by producing selective signals through the conduit wall detectable by a member to produce an activating signal for actuating the downhole well tool by a downhole energy source.
