Objectives of this Thesis are to:
- Develop an awareness of the challenges presented from elevated temperatures
and pressures in well construction.
- Learn the key differences between ―normal‖ condition wells and HPHT wells.
- Understand some of the indicators of thermal- and pressure-related problems.
- Understand the responses which may be made to mitigate high pressure and
high temperature ,,HPHT‘‘ challenges while drilling wells.
HPHT wells are an unavoidable consequence of the ever expanding search for
oil and gas resources around the world. As wells are ...

In addition to encountering HPHT conditions in deeper reservoirs, we also have HPHT
conditions in wells in which we employ steam injection, and in geothermal wells.
