Wiper plug elements and methods of stimulating a wellbore environment

A method of stimulating a wellbore environment, the method comprising the steps of:

• (a) cementing a wellbore casing within a wellbore, the wellbore casing comprising a downhole tool having a valve disposed below a fluid restriction apparatus, the fluid restriction apparatus comprising a tubular member having a seat disposed within a bore of the tubular member and a plug element for landing on the seat, the plug element comprising a dissolvable material;
• (b) opening the valve to place the wellbore casing in fluid communication with a wellbore environment;
• (c) landing the plug element on the seat to restrict fluid communication between the wellbore casing and the wellbore environment;
• (d) performing a pressure test of the wellbore casing;
• (e) dissolving a portion of the plug element causing an increase in fluid communication between the wellbore casing and the wellbore environment;
• and
• (f) performing a stimulation operation in the wellbore environment.

A plug element for an apparatus for restricting fluid flow through a valve disposed in a wellbore casing, the plug element comprising:

• a first dissolvable material;
• a first shape in which fluid flow is restricted through a bore of a valve disposed in a wellbore casing when the plug element is landed on a seat, the seat being disposed above the valve;
• and
• a second shape in which the plug element is transported through the seat and the valve bore to remove debris disposed in the valve bore, the second shape resulting from dissolution of a portion of the first dissolvable material.
