A proper borehole design (the drilling & casing scheme) 
is an important factor to successfully drill a deep well, in 
drilling for hydrocarbons as well as for recovery of 
geothermal energy. Selection of a casing scheme has 
also a high impact on overall borehole costs.
With the oral presentation an overview on following 
aspects will be given:
- how to plan the casing scheme of a deep well properly,
- which pressures (external, internal) and loads 
(weight, tension, bending, compression) are stressing 
the casing strings, 
- how to design (calculate) casing strings for different 
pressure and load situations, 
- the influence of temperature and temperature 
changes on casing,
- the impact of well design on the capability of 
proper cementation of casing strings, 
- the influence of borehole design on well costs.
