Abstract
A method of unloading a well using a modular adapter having a pump, a pump suction line, and a pump discharge line. The adapter is connected to a subsea wellhead assembly so that the pump suction line communicates with a main bore in the wellhead assembly and the pump discharge line communicates with a production line attached to the wellhead assembly. The production line is isolated from the main bore and the pump draws fluid from within the well and discharges it into the production line. After unloading the well, the adapter can be removed and moved to another location for well unloading.
