Flapper valve tool

A method, the method comprising:

• positioning a downhole tool in a wellbore, the downhole tool comprising:
• a flapper valve assembly for controlling the backflow of fluid into a tubing string, the flapper valve assembly includes at least one flapper;
• and
• a sleeve assembly slidably disposed within at least a portion of the flapper valve assembly and the downhole tool, the sleeve assembly having a deformable portion that deforms when a fluid blocking member is pumped through the sleeve assembly, the deformable portion having an inner diameter that is less than an inner diameter of a majority of the sleeve assembly prior to the fluid blocking member being pumped through the sleeve assembly and the deformable portion having an outer diameter that is greater than an outer diameter of the majority of the sleeve assembly after the fluid blocking member is pumped through the sleeve assembly;
• wherein the deformable portion outer diameter is created by passing the fluid blocking member through the inner diameter to deform the inner diameter and forming the outer diameter of the deformable portion;
• shifting the sleeve assembly in the downhole tool to interact with the flapper valve assembly;
• and deforming the deformable portion of the sleeve assembly by pumping the fluid blocking member through an entire length of the sleeve assembly.
