Abstract

A float equipment assembly includes an inner string that provides a fluid flow path through the float equipment assembly. The float equipment assembly also includes an opening through which a fluid flowing through the inner string exits the float equipment assembly. The float equipment assembly further includes a moveable member, which when repositioned, isolates the inner string. The float equipment assembly further includes a dissolvable material that initially prevents repositioning of the moveable member, where the moveable member is repositioned after a threshold portion of the dissolvable material has dissolved.
