摘要 |
Method and apparatus for identifying lost circulation in subterranean wells, in particular, methods for treating the identified lost circulation zones with fluid compositions that are pumped into a wellbore enter voids in the subterranean-well formation through which wellbore fluids escape, and form a seal that limits further egress of wellbore fluid into the lost-circulation zone.
