Operation of flowing and gaslift wells via one-level elevator

K.P. Aliyev

The operation of flowing and gaslift wells is recommended to perform via gaslift valves and use one-level elevator. The advantages of this method lies in the fact that due to the installation of shutoff-valve and packer of elevator first line, the probability of open flow is excluded, a great amount of tubes and labor force saved, well completion time reduced as well. In case of regime failure in gaslift system, the well does not stops completely and keeps operating with less oil production than previously.
