Abstract
The frac plug device is a wedge type or ramp type frac plug that can seal at a setting position in a large diameter portion of the borehole. The thickness, taper angle, and dimensions of components for passing through the narrowest portion of the borehole during deployment no longer limit the radial expansion. The frac plug device includes a core cone, a segmented cone, a slip device, a segmented cap member, and a core cap member. A simplified setting action sets the high expansion of the slip device by the core cone and the segmented cone. The segmented cone and the segmented cap member increase expansion of the slip device, and the segmented cap member and the core cap member lock the slip device around the core cone in the final expansion configuration at the maximum radial expansion for large diameter portions of the borehole.
