Abstract
A completion string, including an upper completion having a shifting tool, and a lower completion having a hydraulic releaser and a valve responsive to the shifting tool. A method for completing a well, including running the completion string in a borehole, establishing pressure integrity, applying tubing pressure to release the hydraulic releaser, and shifting the valve. A method for completing a well, including running an upper completion connected to a lower completion into a borehole, releasing a hydraulic releaser with applied tubing pressure, and shifting a valve in the lower completion with movement of the upper completion. A wellbore system, including a borehole in a subsurface formation, an upper completion and a lower completion in the borehole, a hydraulic releaser connecting the upper completion to the lower completion, the hydraulic releaser being responsive to applied tubing pressure to releaser the upper completion from the lower completion.
