When the dummy valve is clear of the pocket, the operator will bring the valve to surface and remove it from the lubricator. The operator will then drop downward and allow the pulling tool to latch onto the latch and dummy valve, which can then be retrieved by jarring up. This directs the kickover tool out over the dummy valve. The operator will then start up hole slowly and the KOT kickover tool will make contact with the orienting sleeve located in the top portion of the mandrel. This pressure is held long enough to determine that no communication exists.Īfter a successful hydro-test, the dummy valves are retrieved by wireline, starting with the bottom dummy valve and continuing, in sequence, retrieving the top one last.Īs the kickover tool approaches the depth of the bottom mandrel, the operator will slow the speed and proceed through the mandrel. After the wellhead is flanged, a hydro-test is performed by pumping into the annulus to achieve the specified pressure in the engineering prognosis. The packer is set with the designated weight and the master valve and wing valves are flanged up on the wellhead. Flanging Wellhead / Hydro-testing Casing / Tubing:.As the tubing is correctly placed in the well, the packer is then set in accordance with the specifications in the engineering prognosis. The packer is set somewhere above the perforations to the productive formation. The side pocket mandrels are pre-loaded and hydro-tested, with dummy valves in the pockets. This specifies where the packer, side pocket mandrels and any other downhole production equipment are to be placed in the well. The decision to complete the well implemented by setting and cementing the casing, is followed by running the tubing string.Īn engineering prognosis is then completed. Running the tubing / setting the packer:.In order to further explain all these aspects and more simplify the process, gas lift operations have been described in the next paragraphs:
Gas lift operations and unloading procedure are described in the following demonstration video:
