Title (EN) DEGRADABLE PUMP IN SHOE
(FR) POMPE DÉGRADABLE DANS UN SABOT
Abstract:
(EN) 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.
(FR) Le fait d'incorporer un matériau soluble ou dégradable dans la pointe du bouchon de cimentation et/ou l'équipement de flotteur, permet de pomper un fluide pendant la phase ciment (ou de le transporter par d'autres moyens) pour commencer la dégradation du matériau soluble. Une fois que le matériau est dissous, un trajet d'écoulement est exposé, permettant une communication vers l'arrière ou la formation du puits de forage à travers l'ensemble bouchon et lavoie de passage du sabot.
