초록 ▼

A modular near-surface completion system that positions the production wellheads in a quiescent zone beneath significant wave activity yet within reach of divers for maintenance and inspection. Each subsea well is provided with (a) its own riser, (b) a riser tensioning buoy and (c) a production well tree mounted atop the riser buoy. Produced fluids are transmitted from the well tree to the floating production platform by means of flexible risers suspended in a catenary loop of sufficient length to permit the platform to be maneuvered to position it for drilling or workover of any of the plurality of templates it services.

대표청구항 ▼

A modular near-surface completion system for a plurality of subsea wells in deep water, wherein each of said plurality of subsea wells has been drilled and cased from a mudline and completed with a lower tubing hanger below the mudline, said near-surface completion comprising: a first plurality of production risers, one said production riser extending from each of said plurality of subsea wells to a quiescent zone beneath the surface of the sea; a plurality of riser buoys positioned in said quiescent zone out of a subsurface sea region affected by the action of wind and waves, one each of said plurality of riser buoys being attached to one of said first plurality of production risers, each of said buoys having positive buoyance in an amount exceeding the weight of respective elements it supports; a plurality of well completion trees with a single well completion tree mounted atop each of said riser buoys; means for connecting each of said plurality of well completion trees to an above-surface production facility; means interconnecting at least one of said riser buoys directly to one or more additional adjacent riser buoys of said plurality of riser buoys to increase stability of said near-surface completion system by substantially fixedly interconnecting said adjacent riser buoys, said interconnecting means including a plurality of attachment points capable of accomodating variations in vertical positioning of said adjacent buoys.
