The Innovex Casing Floatation System allows casing to be floated in the hole, significantly reducing friction. The reduced friction allows the casing to be run at a quicker pace and ensures enough string weight is available to make it to total depth.
The Casing Floatation System incorporates the entire shoe track with integral debris catcher. The Casing Float Sub is typically placed at the top of the curve and allows the lateral casing section to be run dry and float in the hole. Once the casing is landed, applied surface pressure ruptures the Casing Float Sub, thus allowing for a conventional cement job.
The system can incorporate either a single cement wiper plug or a two plug lead-follow system.
