- Introduction to Deepwater Drilling
- Deep Water History
- Deepwater Locations and Geology
- Overburden and Compaction, Pore and Fracture pressures
- Metocean & Currents
- Station keeping
After the introduction to deepwater wells and a offshore drilling history. Stundent will look at the deepwater geological setting in various deepwater locations in the world. Here we discuss how deepwater reservoirs are formed and how many challenges associated with deepwater can be explained by the geological setting.
Then Overburden and compaction in deepwater locations, leading into the critical differences in pore and fracture pressures between deepwater and shallow water operations. Finally participant will look the metocean setting for deepwater wells, and the requirements for station-keeping in this environment
- Rig Selection
- Open water Operations (ROV’s)
- Subsea Wellheads and Casings
- BOP Systems
- Drilling Riser Systems
- Drilling Equipment For Deepwater
- Deepwater Well Control
First sessions will address the rig selection and “Open Water Operations” which take place before setting the Blowout Preventors (BOPs), to conductors, wellheads, casing, and cementing. Following, students will focus on BOPs, riser systems, and what drilling equipment is required for deepwater wells compared with other offshore wells. This include drilling systems as well as mud handling and riser handling systems. Finally at the end of the day well control in deepwater will be covered, including a brief discussion of the BP Macondo well and the consequences of this disaster on the industry.
- Drilling Challenges
- Shallow Hazards / Hydrates
- New Technology; Dual Gradient Drilling, MPD
- Completions & Interventions
- Operations Management
During this day, participants will review some of the key drilling challenges such as shallow water flows, shallow gas, and hydrates. Then a review of drilling fluids and subsalt issues. Some new drilling techniques such as MPD and Dual Gradient Drilling will be mentioned briefly.
Finally, completions and interventions in deepwater to provide insight into how these differ from shallow water wells, ending the session day with the management of deepwater operations, in terms of the demands of complex wells, advanced rig systems, and the high cost operating environment.
