Apparatus, method and system for plugging a well bore

Apparatuses, systems and methods for plugging a well bore. A plug formation apparatus includes a plug support tool having a substantially cylindrical and hollow body having one or more ports for fluid communication between an interior of the plug formation apparatus and an annulus of a well bore, a base extending radially around an outer surface of the body, and an elastically deformable member extending radially around an outer surface of the body beyond the base and supported by the base; a top-of-cement bypass sub having one or more ports, actuatable between a closed position and an open position; a detachment member coupled with the top-of-cement bypass sub; and a length of tubing fluidically coupled with an upper portion of the plug support tool and a lower portion of the top-of cement bypass sub.
