Zusammenfassung:	Methods and systems for conducting liner drilling and subsequent completion of the drilled section by cementing and anchoring the liner (32) into place. The methods and systems prevent the liner from being cemented in a bent or corkscrewed configuration. Additionally, there are no exterior components associated with the liner during drilling so as to allow relatively unrestricted return of drilling mud and cuttings. L'invention concerne des procédés et des systèmes de forage par colonnes perdues et de complétion subséquente d'une section forée par cimentation et ancrage des colonnes perdues (32). Ces procédés et systèmes empêchent les colonnes perdues d'être cimentées dans une configuration coudée ou en serpentin. De surcroît, aucun élément extérieur n'est associé aux colonnes perdues pendant le forage, ce qui permet un retour relativement direct des boues et déblais de forage.
