HP/HT Drilling Engineering
This course covers high pressure and high temperature drilling engineering. Participants study HP/HT definitions and challenges, pore pressure and narrow margins, drilling fluids at extreme conditions, casing and wellhead design, equipment ratings and elastomers, well control at HP/HT, kick tolerance, annular pressure build-up, operating practice and risk management.
Description
High pressure and high temperature wells sit at the limits of equipment, materials and prediction methods. Margins between pore pressure and fracture gradient are narrow, kick tolerance is small, mud properties change substantially downhole, elastomers and electronics degrade, and the consequences of a well control event are more severe than in conventional wells.
This course covers the engineering and the operating discipline. It starts with HP/HT definitions and classifications and the specific challenges each level brings, then covers pore pressure prediction and narrow margin management at extreme conditions. It covers drilling fluid behaviour at high temperature and pressure, including rheology, density changes, sag and thermal stability, and the hydraulics consequences. It then covers casing, wellhead and equipment design and ratings, elastomer and material selection, and well control at HP/HT including kick tolerance, gas behaviour and kill design. The course closes with annular pressure build-up, operating practice, monitoring requirements and the risk management framework HP/HT wells require.
At HP/HT conditions, small errors become large ones quickly. Kick tolerance may be only a few barrels, meaning a kick must be detected and shut in almost immediately; mud density changes with temperature and pressure by enough to matter for pressure control; and equipment operating close to its rated pressure has little margin for the surge of a shut-in.
Mud behaviour is harder to predict. Downhole rheology differs substantially from surface measurements, equivalent circulating density calculations that ignore compressibility and thermal expansion can be significantly wrong, and barite sag risk is high in hot deviated wells. Fluid design and hydraulics modelling therefore need temperature and pressure dependent data rather than surface values.
Materials and elastomers set hard limits. Seals degrade, electronics fail, and casing strength falls with temperature, which narrows the design margins at the same time as the loads increase. HP/HT wells are therefore slower, more carefully monitored and more procedurally controlled than conventional wells, and the planning reflects that.
By the end of this training, participants will be able to:
- Define HP/HT classifications and the challenges at each level.
- Predict pore pressure and manage narrow margins at extreme conditions.
- Assess drilling fluid behaviour at high temperature and pressure.
- Calculate hydraulics and equivalent circulating density with temperature and pressure effects.
- Manage barite sag and fluid stability in HP/HT wells.
- Design casing, wellheads and equipment for HP/HT service.
- Select materials and elastomers within temperature and pressure limits.
- Calculate kick tolerance and apply well control at HP/HT conditions.
- Assess and mitigate annular pressure build-up.
- Apply HP/HT operating practice, monitoring and risk management.
The course is instructor-led. HP/HT effects are developed through calculations comparing conventional and extreme conditions, and participants work through a well design case including margins, fluid design, casing and well control planning. Field cases cover HP/HT wells and incidents. Participants are encouraged to bring their own wells for discussion.

- Design and drill HP/HT wells with adequate margin and control.
- Reduce well control risk in low kick tolerance conditions.
- Improve fluid and hydraulics prediction at extreme conditions.
- Select materials and equipment correctly for HP/HT service.
