Audience

    • Drilling engineers, drilling supervisors, drilling superintendents.

Level

  • Advanced
  • To provide a comprehensive knowledge on how to design and execute an HPHT well in an exploration or development context.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • understand the design concepts related to an HPHT well,
  • learn about required operational preparedness aspects of HPHT drilling operations,
  • assimilate the key aspects for executing successful operations in HPHT drilling.
Course Content

GENERALITIES

0.5 day

  • Applications, terms and definitions.
  • PPFG aspects of HPHT reservoirs (effect of depletion, geomechanics).
  • Well architecture specificities of HPHT wells.

BASIC DESIGN ENGINEERING

1 day

  • 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…).
  • Annulus management systems (N2 cushion, burst discs, crushable foams…).
  • Subsea HPHT specificities (wellhead fatigue, X-Mas tree choice, APB).

ADVANCED HPHT WELL ENGINEERING

1.5 days

  • Casing wear (modeling, measurement, remedial).
  • Wellhead growth (modeling and impacts, heat island effect).
  • Fluids & cement aspects of HT environments.
  • 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).
  • Introduction to MPD.
  • In-field drilling (depletion and stress caging…).

OPERATIONAL PREPARATION

0.75 day

  • Rig inspection program for HPHT operations.
  • Equipment specific to HPHT (mud coolers, kick assembly, early-kick-detection…).
  • Hydrates (formation mechanisms, prevention).
  • HPHT checklists.
  • HPHT procedures (pit management and discipline, breaking circulation, connections, flow checks, tripping procedures, pump out of hole).
  • HPHT coring and wireline logging.

OPERATIONAL EXECUTION

1.25 days

  • ECD management.
  • Wellbore breathing (breathing vs. kick, loss-gain scenarios, supercharging mechanisms, fracture…).
  • Well control aspects.
  • (E)LOT/FIT in HPHT.
  • Mud weight management.
  • Fingerprinting (dummy) connections, swab & surge, compressibility test, drain back/flow volume…).
  • Case studies (HPHT train wrecks, database analysis of exploration and development wells).
