Defines a valid instance of a type of wellbore trajectory shape. Common types are: build & 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.

name (M, K: ndt_name)

The common name by which a trajectory type is referred to. Examples are: build & hold, S shaped, vertical, horizontal.


source (M, I: ref_source)

The provider of this instance of reference information. If this instance is provided by POSC, then this attribute must be "POSC". Each ref_wellbore_trajectory_shape must provided by one ref_source. Inherited from reference_behavior.


description (O: ndt_comment)

A comment about the trajectory type.


status (O, I: ndt_instance_status) (0644)

The status of this instance in the version of Epicentre running in a data store. This is an enumerated datatype for which the following are the possible values: current, provisional, deprecated. Current - use without restriction. Provisional - use with caution, this value is for comment and may not appear in future releases of Epicentre. Deprecated - avoid use if possible, it is planned to remove this value in the next major release of Epicentre. Inherited from reference_behavior.


code_alias (I, V: SET[0:?] ref_code_alias(standard_code))

Defines a list of alternative names associated with this instance. These may be aliases, translations, codes, etc. Each ref_wellbore_trajectory_shape may have one or more ref_code_alias. Inherited from ref_code.


source_reference (O, I: ref_source_reference)

The reference used by source to provide the standard instance, such as Petroleum Industry Data Dictionary (PIDD), Websters Ninth New Collegiate Dictionary, etc. Each ref_wellbore_trajectory_shape may documented by one ref_source_reference. Inherited from reference_behavior.


version (O, I: ref_epicentre_version) (0644)

Describes the version of Epicentre when this status was assigned to this instance of reference behavior Each ref_wellbore_trajectory_shape may version one ref_epicentre_version. Inherited from reference_behavior.
