Abstract
An embodiment of the present invention utilizes a frac plug having an extremely short length. The extremely short length minimizes the amount of dissolvable material that must be utilized in order to maintain the physical integrity of the plug without unduly deforming the cone. Relatively uniform loading of the cone is accomplished by circumferentially locking the slip sections in place during setting. A sufficient quantity of sealing material is provided by angling the slip surface to a degree that allows a sufficient quantity of elastomer or other sealing material to be used in conjunction with backup rings to prevent the sealing material from extruding down towards the slip.
Claims9
A wellbore plug comprising,
- a mandrel,
- an expander cone circumferentially mounted about an outer surface of the mandrel,
- a slip element circumferentially mounted on the outer surface of the mandrel,
- a sealing element circumferentially mounted on an outer surface of the expander cone,
- an anti-extrusion element circumferentially mounted on an outer surface of the expander cone,
- wherein the anti-extrusion element is axially located between the sealing element and the slip element,
- further wherein the anti-extrusion extends radially beyond an outer surface of the slip element.
