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.

Abstract: Methods of plugging a hydrocarbon well by using degradable plugs plus a degradable tape to ensure pressure testing to 10,000 psi. When the plug is no longer needed, a degradation fluid or fluids are pumped downhole and that fluid or fluids degrade the degradable plugs and degradable tape, thus avoiding the production of any solids large enough to clog or block equipment.
