Deepwater Drilling Engineering
This course covers deepwater drilling engineering. Participants study deepwater conditions and challenges, shallow hazards, riserless and riser drilling, mud and hydraulics in cold deep water, narrow pressure margins, well design and casing programmes, subsea wellheads and BOPs, well control in deep water, operational practice and cost management.
Description
Deepwater drilling combines narrow pressure margins, cold seabed temperatures, long risers, subsea equipment and very high daily cost. Each of these changes the engineering: fracture gradients are low because of the water column, mud properties change in the cold riser, riser margin may not exist, and every piece of pressure control equipment sits on the seabed where access is slow.
This course covers that engineering. It starts with deepwater conditions, the pressure window problem created by the water column, and shallow hazards including shallow water flow and gas. It covers riserless top hole drilling and the transition to riser drilling, drilling fluids and hydraulics in cold deep water including rheology, equivalent circulating density and barite sag. It covers well design and casing programmes for narrow margins, subsea wellheads, casing hangers and seal assemblies, and subsea blowout preventers. The course then covers well control in deep water, including riser gas and riser margin, operational practice, and the cost structure and efficiency measures that matter at deepwater day rates.
The water column is the root of the pressure problem. Seawater has a lower gradient than rock, so fracture gradients below the mudline in deep water are much lower than at the same total depth onshore. The window between pore pressure and fracture gradient is therefore narrow from the start and narrows further with depth, which drives casing points, mud weights and the frequent use of managed pressure techniques.
Temperature is the second effect. Seabed temperature near freezing cools mud in the riser, raising its viscosity and gel strength, increasing pressure losses and encouraging barite sag. Rheology that is correct at bottomhole temperature may be unmanageable in the riser, which is why deepwater fluid design considers the whole temperature profile.
Riser margin is a well control consideration unique to floating operations. If the riser is disconnected, the mud column is replaced by seawater and bottomhole pressure drops. Carrying enough mud weight to keep the well dead after disconnection, which is riser margin, is often impossible within the narrow window, so operations proceed without it and the consequences are managed procedurally.
By the end of this training, participants will be able to:
- Explain deepwater conditions and the challenges they create.
- Assess shallow hazards, including shallow water flow and shallow gas.
- Plan riserless top hole drilling and the transition to riser operations.
- Design drilling fluids and hydraulics for cold deepwater conditions.
- Manage barite sag, rheology and equivalent circulating density in deep water.
- Design casing programmes for narrow deepwater margins.
- Describe subsea wellhead systems, hangers and seal assemblies.
- Describe subsea blowout preventer systems and their operation.
- Apply well control principles in deep water, including riser gas and riser margin.
- Manage deepwater operational practice and cost.
The course is instructor-led. Deepwater engineering is developed through a well design case covering pressure window assessment, casing programme, fluid design and well control planning. Equipment is covered with drawings and specifications, and operations with procedures and field cases including deepwater incidents. Participants are encouraged to bring their own wells for discussion.
