Abstract
A technique facilitates improved actuation and use of packers disposed along a well string and placed in a borehole, e.g. a wellbore. A plurality of packers may be disposed along a base pipe, e.g. a production tubing. Each packer has an expandable sleeve which may be expanded into a fully expanded configuration establishing a secure, sealing engagement with a surrounding wall. e.g. a surrounding wellbore wall. Additionally, a hydrolock prevention valve system comprises a valve which may be actuated to allow or block the flow of fluid from an annular region or regions between the packers.
