Abstract:

The present disclosure provides a modular insert float system and method that can be inserted into a casing and attached to the casing internal surface by internal slips and sealing components. The system is modular in that three main components: an upper valve assembly, a lower valve assembly, and a pair of casing anchor and seal assemblies along with top and bottom shoes form a kit that can be used for virtually any casing of a given size regardless of the threads, casing material grades, length of joint, or other variations. Further, the system allows for insertion of the casing into the wellbore without damaging the formation from forcing wellbore fluid into the formation and causing the loss of wellbore fluid in the wellbore.
