This course aims to provide a comprehensive knowledge on how to design and execute an HPHT well in an exploration or development context.
Public :
Engineers, supervisors, superintendents operators from operators, contractors and service companies who will be involved in geothermal, storage or oil/gas drilling operations.
Level :Expert
Prerequisite :
Comprehension and understanding of well design, well construction operations, and management.
To be familiar with and understand basic geomechanics, drilling operations, well placement, well planning, and drilling fluids basics.
Understanding of well control concepts and procedures is a plus.
Course Content
GENERALITIES
-
Duration : 3 hours
Applications, terms and definitions.
PPFG aspects of HPHT reservoirs (effect of depletion, geomechanics).
Well architecture specificities of HPHT wells.
BASIC DESIGN ENGINEERING
-
Duration : 6 hours
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
-
Duration : 9 hours
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
-
Duration : 4.5 hours
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
-
Duration : 7.5 hours
ECD management.
Wellbore breathing (breathing vs. kick, loss-gain scenarios, supercharging mechanisms, fracture…).
Case studies (HPHT train wrecks, database analysis of exploration and development wells).
