Abstract
A system is disclosed for subsea transportation of a hydrocarbon production stream utilizing a wellhead aspirator to reduce wellhead flowing pressure. By using the Bernoulli effect, a head is delivered to the flowing stream that enables the crude oil/water/gas fluid within the system to be moved farther distances than wellhead pressure alone would allow.
