Course Content

  • ADVANCED COMPLETION

      • Subsea smart completion: objectives, technology description and implantation.
      • Multilateral completion.
      • Single trip multizone gravel pack system: introduction, dual string and single string, BJ & Halliburton comparison, offshore wells operation BJ MST system key components.
      • Tubingless completion: objectives, tubingless well architecture and equipment innovation.
      • Would it make sense to add a word about WABs? Cementless expandable lower completion?
  • HPHPT WELLS

      • HPHPT definitions:
      • API.

      • Basic design engineering:
      • Casing design specific to HPHT (thermal simulations/introduction to limit-state and reliability based design/survival loads).
      • OCTG choice (material grade, SSC, qualification).
      • OCTG connector choice (test and qualification).
      • Well equipment (liner, wellheads, casing hangers…).
      • Subsea HPHT specificities (wellhead fatigue, X-Mas tree choice, introduction to APB).
      • Annulus management systems (N2 cushion, burst discs, crushable foams…).
      • Well architecture specificities of HPHT well. Real case presentation.
      • Advanced HPHT well engineering:
      • Casing wear (modeling, measurement, remedial).
      • Wellhead growth (modeling and impacts, heat island effect).
      • Fluids and cement aspects of HT environments (mud weight reference at 50°C).
      • Kick tolerance modeling (dispersed modeling w/drill bench or equivalent, limitations of single bubble in HPHT).
      • Hydraulic modeling in HPHT operations.
      • Logging (current HT limitations on MWD tooling).
      • Infill drilling.
      • Operational preparation
      • Rig inspection program for HPHT operations.
      • Importance of bridging document/JDM between contractor and operator.
      • Equipment specific to HPHT (mud coolers, kick assembly, dart sub, MPD…).
      • Hydrates (formation mechanisms, prevention).
      • HPHT checklists (example supplied).
      • HPHT procedures (pit management and discipline, breaking circulation, connections, Horner plot flow checks, tripping procedures, pump out of hole or stripping if MPD).
      • Operational execution
      • ECD management.
      • Wellbore breathing (breathing vs. influx, loss-gain scenarios, supercharging mechanisms, fracture…).
      • Well control aspects.
      • LOT/FIT in HPHT.
      • Mud weight management.
      • Fingerprinting (dummy) connections, swab and surge, compressibility test, drain back/flow volume…).
      • Case studies (HPHT train wrecks, database analysis of exploration and development wells).
  • MANAGED PRESSURE DRILLING

      • Introduction:
      • Definition (IADC), history and objectives.
      • Why using MPD?
      • Surface back pressure (SBP) introduction.
      • Main components and layout:
      • Rotating control device (RCD).
      • Choke manifold including Coriolis mass flow meter (example of real layout).
      • Drill pipe non return valves.
      • MPD operations with RCD:
      • Drilling: difficulties to differentiate “well breathing-supercharge” and an “influx”; management of the surface back-pressure (manual, SBP mode, APC mode, “C” mode); use of PWD; kick detection (EKD, virtual trip tank); limitations and risks, well control matrix.
      • Tripping/stripping: POOH (adjusting SBP); temperature effect mud weight (static and dynamic temperatures), mitigation; mud cap, why and when, risks and limits; RIH; procedure example.
      • Dynamic fit/lot: principles, dynamic FIT with PWD, dynamic LOT with PWD and Coriolis flow meter, real time SBP setting.
      • Dynamic pore pressure (pp) assessment: principle, SBP and AFL, MW adjustment for drilling and tripping/stripping.
      • Casing RIH and cementing: case study.
      • Conclusion:
      • Advantages of MPD.
      • Risks and limitations.
  • Knowledge assessment

Learning Objectives

  • Upon completion of this course, participants should be able to:
  • work on complex completion issues,
