Deepwater oil & gas wells are often extremely expensive (and often carry high risk) especially if they are drilled with the latest generation semi-submersibles or drill ships, which typically have operating day rates in excess of $1 million per day. Further, if they’re in particularly remote locations with water depths of 10,000 ft. or so and burn significant quantities of fuel through staying on location due to harsh wind / wave / storm force loadings.
This course covers those operational aspects in detail, which will maximise the success of the drilling phase of the well to be drilled (e.g. dual operations / activity etc.) and also looks at the use of surface BOP stacks in the moon-pool.
To maximise learning, a wide range of Case Histories are also presented with delegates being given the opportunity as teams to drill their own well on paper (DWOP). Presentation material is through the use of Manuals, PowerPoints, Case Histories, videos and digital film.
Duration: 5 Days
Skill Level: Intermediate
This course covers the following topics:
- Deepwater: The Challenges;
- Commonest reasons behind cost over-runs & well failure;
- The Deepwater Environment – wind, wave, current & storm loadings; Environmental effects on marine vessels;
- Stability, Choice of Vessel – including 5th & 6th Generation;
- Prior to Spudding the Well: Seabed Condition, Shallow Gas, Conductor & Surface Casing Setting; BOPE Installation, The Effects of Weak Formations On Kick Tolerance, Preliminary Well Design.
- Spudding the Well. Subsea Wellheads. Temporary & Permanent Guidebases. Templates. Sub-sea BOP Stacks, H-4 Connector, The LMRP, Riser System, Telescopic Joints, Riser Tensioner, Heave Compensator.
- Drilling to TD.
- Personnel who are involved with Deepwater Drilling especially Operational personnel but also suitable for Planning personnel too.
- Service Company Personnel / Well Reviewers / Examiners
Prerequisite: Previous operational knowledge on more standard offshore wells.
