intersection_role (I, V: SET[0:?] space_time_operation(intersecting_object))

Indicates a space/time operation for which the object is involved as an intersecting agent. For projection, this is the screen on which an object is being projected.

Specifies various materials which are found at this position in the wellbore. Each wellbore_composite_position may locate one or more other_material. Inherited from position_in_wellbore.

Defines the set of classifications of this position with respect to its degree of uncertainty. Each wellbore_composite_position may be classified by one or more position_uncertainty_classification. Inherited from earth_model_object.


primary_role (I, V: SET[0:?] space_time_operation(primary_object))

Indicates a space/time operation for which the object is involved as a primary agent. For degeneration, this object is being degenerated. For projection, this object is being projected onto another object. For proximity, this is the container object. Each wellbore_composite_position may be the primary object for one or more space_time_operation. Inherited from topological_object.


primary_topological_relationship (I, V: SET[0:?] topological_relationship(primary_topological_object))

Indicates a topological relationship in which the topologic object has the role of primary agent. For an object intersection type of "inside" this is the containing role (e.g., if a city is inside a county then the county would be the primary agent). For all other object intersection types the roles are symmetrical and both relationships must be searched for a particular object. For example, if a wellbore and a formation overlap then either could be chosen as the primary agent with the other chosen as the secondary agent. Each wellbore_composite_position may be primarily involved in one or more topological_relationship. Inherited from topological_object.


pty_bounding_rectangle (I, V: SET[0:?] pty_bounding_rectangle(composite_spatial_object))

This points to the rock feature part that this earth model object is representing spatially. Each wellbore_composite_position may be located by one rock_feature_part. Inherited from earth_model_object.


secondary_topological_relationship (I, V: SET[0:?] topological_relationship(secondary_topological_object))

Indicates a topological relationship in which the object is in the role of secondary agent. For an object intersection type of "inside" this is the contained role (e.g., if a well is inside a field then the well would be the secondary agent). For all other object intersection types the roles are symmetrical and both relationships must be searched for a particular object. For example, if a wellbore and a formation overlap then either could be chosen as the secondary agent with the other chosen as the primary agent. Each wellbore_composite_position may be involved in one or more topological_relationship. Inherited from topological_object.


source_space_time_operation (I, V: BAG[0:1] space_time_operation(resulting_object))

Indicates the space/time operation from which a topological object was the result. For addition, this is the union of two objects. For degeneration, this is the degenerate object. Each wellbore_composite_position may be the result of one space_time_operation. Inherited from topological_object.

Indicates various activities which take place at this location along a wellbore path. Each wellbore_composite_position may locate one or more wellbore_activity. Inherited from position_in_wellbore.


wellbore_composite_position (O, I: SET[0:?] wellbore_composite_position(position_in_wellbore))

Indicates that this location is part of the specification of a composite position. Each wellbore_composite_position may be a part of one or more wellbore_composite_position. Inherited from position_in_wellbore.
