Abstract
By incorporating a dissolvable or degradable material into the wiper dart and/or float equipment, a fluid can be pumped during the cement phase (or spotted by other means) to begin degradation of the dissolvable material. Once the material is dissolved, a flow path is exposed, allowing communication to the backside or formation of the wellbore through the plug set and shoe track.
