摘要:
A method for cementing a wellbore having a lost circulation zone includes installing a cement basket around a casing string having a casing diameter, and running and setting the casing string in the wellbore. The cement basket is set in proximity of and up hole from the lost circulation zone. The method includes pumping a cement slurry, through the casing string, to a first depth downhole from the cement basket, running a first tubing, having a tubing diameter, into an annulus between the casing string and the wellbore, and pumping the cement slurry, through the first tubing, to a second depth up hole from the cement basket. The tubing diameter is less than the casing diameter.
