<p>A methodology and system facilitate performance of an operation in tubing, such as wellbore tubing. A seat is placed in the tubing so that an object may be delivered along an interior of the tubing for engagement with the seat. The object is designed with a non-degradable component, e.g. wiper, mounted on a degradable core. In many applications, fluid may be used to move the object along the interior of the tubing and into engagement with the seat. As the object moves along the interior, the wiper is used to wipe, e.g. scrape, material from an inside surface of the tubing. After the object engages the seat, pressure may be applied along the interior of the tubing to actuate a desired tool. Upon completion of the procedure, the core may be degraded, e.g. dissolved, and thus removed from the tubing.</p> |
