Wiper dart with reinforced drive element

A well system, comprising:

• a work string extended within a wellbore and coupled to a wellbore liner;
• and
• a wiper dart conveyed into the work string to hydraulically force a fluid through the work string and into the wellbore liner, the wiper dart including:
• one or more wiper elements disposed about a mandrel and each comprising a wiper cup that extends radially outward and rearwardly relative to the mandrel to sealingly engage an inner wall of the work string;
• a nose assembly coupled to the mandrel;
• and
• a drive element disposed about the mandrel and including a shoe and a cup coupled to the shoe,
• wherein the cup of the drive element extends radially outward and rearwardly from the shoe and exhibits a maximum diameter less than or equal to a maximum diameter of the one or more wiper elements, and wherein the shoe provides at least one of axial and radial support to the cup,
• wherein the cup of the drive element provides an inner cup surface and an outer cup surface,
• wherein the outer cup surface provides a reinforced section that engages an end wall defined by the shoe, and
• wherein the end wall extends at a first angle offset from a longitudinal axis of the drive, the first angle ranging between 1° and 90° to provide radial support to the cup of the drive element.

A method, comprising:

• pumping a fluid into a work string extended within a wellbore and coupled to a wellbore liner;
• pumping a wiper dart into the work string, the wiper dart including one or more wiper elements disposed about a mandrel, a nose assembly coupled to the mandrel, and a drive element disposed about the mandrel and including a shoe and a cup coupled to the shoe,
• wherein the cup exhibits a maximum diameter less than or equal to a maximum diameter of the one or more wiper elements,
• wherein the cup of the drive element provides an inner cup surface and an outer cup surface,
• wherein the outer cup surface provides a reinforced section that engages an end wall defined by the shoe, and
• wherein the end wall extends at an angle offset from a longitudinal axis of the drive,
• the angle ranging between 1° and 90° to provide radial support to the cup of the drive element;
• engaging an inner wall of the work string with the one or more sealing elements as the wiper dart advances downhole and thereby hydraulically forcing the fluid into the wellbore liner;
• propelling the wiper dart through a reduced diameter section defined in the work string with the drive element;
• and
• providing at least one of axial and radial support to the cup with the shoe as the wiper drive element propels the wiper dart through the reduced diameter section.
