Beschreibung
Zusammenfassung:	An earth-boring tool includes a bit body having a face on which two different types of cutters are disposed, the first type being cutting elements suitable for drilling at least one subterranean formation and the second type suitable for drilling through at least one elastomeric component of a casing string, as well as a casing shoe and cement. Methods of drilling with an earth-boring tool include engaging and drilling an elastomeric component using at least one abrasive cutting structure. La présente invention concerne un outil de forage comprenant un corps de trépan ayant une face sur laquelle deux types différents de lames sont agencés, le premier type coupant des éléments appropriés pour forer au moins une formation souterraine et l'autre type étant approprié pour forer à travers au moins un composant élastomère d'une colonne de tubage ainsi qu'un sabot de tubage et du ciment. Des procédés de forage avec un outil de forage comprennent la mise en prise et le forage d'un composant élastomère en utilisant au moins une structure de coupe abrasive.
