Abstract
A wellbore tubular flotation device comprises a housing having a locking element disposed thereon. The housing is shaped to move through an interior of a wellbore tubular segment. The locking element is shaped to engage the interior of the wellbore tubular segment. The locking element comprises a locking mechanism configured to urge the locking element into contact with the interior of the wellbore tubular. A burst disk is engaged with the housing and is shaped to close the tubular segment to fluid flow. A release mechanism is configured to reverse the urging of the locking mechanism when a release tool is moved through the housing.
