| Entity Type | Table |
| Description | Defines a valid instance of a type of wellbore trajectory shape. Common types are: Build and Hold, S Shaped, Vertical, Horizontal. In the early stages of well planning, this information, along with some key parameters, are used to generate an approximate well profile - without the requirement for detailed trajectory planning. This information is also of value for wells that have already been drilled because it is difficult to categorize wells by their detailed trajectory. |
