The Slim-X design combines expandable liner hanger and conventional pump down plug technologies. The design utilizes casing as a supporting member, transferring the load from the ball to the ball seat, through the slips and onto the casing. Pressure exerted on the ball during stimulation completes the setting operation while continuing to reinforce the integrity of the tool’s seal, forming a tighter seal as pressure is increased. The tool contains only one quarter the material of standard pump down plugs. The load transfer technology allows the minimalistic design to be feasible. After use, the plug will dissolve in standard chloride solution or even in very low-salinity fresh water, depending on plug material.
