Abstract
Disclosed are fluid handling systems and methods for mitigating the effects of pressure drops that occur at the startup of subsea pumps associated with liquid producing reservoirs. The systems and methods are particularly useful in conjunction with subsea pumps used for producing liquids from high-pressure, low permeability hydrocarbon reservoirs. The systems and methods can mitigate damage to reservoir completions and reservoirs caused by high pressure transients downstream of the pump. A choke valve is used to restrict the flow of the liquids prior to the startup of the subsea pump. After the start of the subsea pump, the choke valve is gradually opened while a recirculation valve is gradually closed, and a full bore valve is opened.
