Abstract:
A subsea well production system has a natural drive mode and a lift-assist mode using a submersible pump. The submersible pump can be installed while the well is live. The well system has a downhole safety valve in the production tubing. The operator closes the downhole safety valve and lowers an electrical submersible pump assembly into the production tubing. Once landed, the valve is opened and the pump assembly placed in operation.
