In 2016, a client approached Stena Drilling to work on a concept for taking crude oil to the rigs’ hull storage tanks. Taking the crude oil into the hull storage tanks allowed the client to mitigate any unnecessary shut-ins associated with flare-out situations. This was vital to this operation as the interrupted flow meant that downhole gauges installed in five wells already drilled in the field could collect data on the reservoir performance.
The current trend for highly mobile deepwater rigs is for bigger drillships and semi-submersibles with ever-increasing building costs. Stena Drilling proposes a smaller drillship or semi-submersible, the DrillSLIM drillship or DrillSLIM semi-submersible to dramatically reduce the costs of wells in water depths up to 7500ft and relatively benign conditions.
DrillSLIM Basis of Design
Drilling MPD, UBE or Dual Gradient Riserless Drilling
High-pressure riser and sub-surface BOPDrill, complete and intervene in subsea wells
Ability to drill a subsea 15,000ft slim well in 7,500 water depth
Well intervention and TTRD capability
