ABSTRACT:
A new method for introducing wellbore cement into a wellbore shoe joint has been invented, the shoe joint having a hollow tubular body, the shoe joint containing an amount of wellbore fluid, the shoe joint disposed in a wellbore cementing system between a float shoe, guide shoe, or other flow apparatus beneath the shoe joint, and a hollow tubular member above the shoe joint, the hollow tubular member being a lower part of a wellbore tubular string of a plurality of tubular members (e.g., casing) extending from an earth surface down into a wellbore, the method including moving a wellbore wiper plug into the hollow tubular body of the shoe joint, moving the plug within the shoe joint to push wellbore fluid from the shoe joint and, in one aspect, debris in the fluid, the fluid flowing to the float shoe, guide shoe or other flow apparatus, flowing wellbore cement into the hollow tubular body of the shoe joint.
