Abstract
A system includes coiled tubing configured to be lowered into a well using a reel. A bottom-hole assembly is connected to a downhole-most end of the coiled tubing. A fail-safe valve is installed within the coiled tubing at a location up-hole from the bottom-hole assembly. A fluid is configured to flow within the coiled tubing. The fail-safe valve is configured to prevent the fluid from flowing in an up-hole direction and permit the fluid from flowing in a downhole direction.
