Keywords (the order of these keywords does not matter, except from the OBJECT keyword – this keyword should always be the first one).

Keyword	Description	Optional	Comment
WELLDESIGN	Specifies the object type in this file	No	One value is expected: 1. Name of the well design
TYPE	Specifies the WellDesign type	Yes	One value is expected: 2. Type of well design (default = UNDEFINED) When this keyword is not included, the default type is applied.
DLSUNIT	Specifies the dls units	Yes	One value is expected: 1. Dls unit (Default = m/rad) For the Depth the unit can be: 1. rad/m (radians/meter) – default unit 2. rad/ft (radians/feet) 3. deg/m (degrees/meter) 4. deg/ft (degrees/feet) 5. deg/10m (degrees/10 meter) 6. deg/30m (degrees/30 meter) 7. deg/30ft (degrees/30 feet) 8. deg/100ft (degrees/100 feet) When this keyword is not included, the default unit is applied
