Abstract
Methods for sealing a wellbore include placing a barrier material within an annular space between a wellbore tubing and a wellbore casing, wherein a seal is placed across or below openings in the wellbore tubing at at least one location above a lowermost tubing to annulus opening. In some embodiments, an intervention tubing may be used to insert the barrier material into successively exposed ones of the annulus openings, whereby no seal sleeve is needed.
