  • Coiled tubing through production tubing zone isolation and production method
    Patent number: 10352139
    Abstract: An existing well has zones that respectively produce water and desired fluids. Existing production tubing is in the well to a location uphole of the producing zones and preferably in a lateral portion on the borehole. The water producing zone is between the surface and the productive zone. A coiled tubing string with a straddle assembly of inflatable isolation packers is run through the production string. An optional milling out of the lower end of the production string can take place first. The inflatable straddle assembly is run past the end of the production string for placement to straddle the water zone while allowing production from the productive zone. The coiled tubing serves as the new production tubing for the productive zone. One or more zones can be isolated or aligned for flow from productive zones.
