Abstract: A system for bringing producing oil and gas from a subsea gathering manifold or wellhead, including a loop having an upper end at the surface and a lower end below the surface, the loop rotatable around a closed path, and production vessels attached to the cable loop, each production vessel having a hollow interior, the weight of the plurality of production vessels sufficient, when filled with seawater, to cause the production vessels to sink, the plurality of production vessels each having an inlet pipe. The system also includes a plurality of receivers attached to the production gathering manifold or wellhead that receive production fluid, the receivers engaging production vessels and filling them with well fluid while seawater is discharged from the production vessels, the production fluid having a lower density than ambient seawater so that the production vessels become buoyant when filled with the production fluid.

Abstract: A method of producing oil and gas from a gathering manifold or a well. The method includes the steps of channeling field production into a sealed vessel through an inlet pipe, and permitting oil and gas components of the field production to separate naturally from water and other fluids within the vessel. The method further includes the steps of evacuating the separated oil and gas from the vessel via pipelines attached to the vessel at locations corresponding to the separated oil and gas, and pumping seawater into the vessel to pressurize the vessel and thereby aid in the production of oil and gas from the vessel.
