ExtensionName The names of agreed extensions to WITSML. This list may be locally extended but it is recommended that new names be approved by the WITSML SIG before use. Each standard name must define its data type. For string types, the maximum length must be defined in number of characters. For measures, the expected measure class must be defined. WITSML dummy-example-string This is an example for the purpose of demonstrating the capabilities. This name should not be used and can be removed from a production file. It describes a string of maximum length of 64 characters which can be used in the commonData of any object. The semantics of the name would be defined in this description field. string 64 .//commonData/extensionNameValue dummy-example-measure This is an example for the purpose of demonstrating the capabilities. This name should not be used and can be removed from a production file. It describes a length measure which can only be specified in the commonData of the well and wellbore objects. The semantics of the name would be defined in this description field. The extensionMeasureClass constrains the allowed units of measure for each value. The extensionDataType value of double constrains the size of each value. double length /well/commonData/extensionNameValue /wellbore/commonData/extensionNameValue dummy-example-dateTime This is an example for the purpose of demonstrating the capabilities. This name should not be used and can be removed from a production file. It describes a dateTime value which can be specified anywhere in the tubular object. The semantics of the name would be defined in this description field. dateTime /tubular//extensionNameValue LithologyType These values represent the lithological terminology used in descriptions of rock cuttings in mud logs.

NameTagTechnology Defines the mechanisms for attaching an equipment tag to an item. WITSML tagged Independent identification components attached or embedded to a larger component for purposes of identification of the larger component. Tags typically use electronic, radio or sound based technologies and that require a special non-optical device to read them. Radio Frequency Identification (RFID tags) are of this type, as are some magnetic and sound based identification technologies. labeled An optical label attached to a component. The label may be glued, riveted or attached by some other method and may contain a serial number, barcode or other optically recognized information. Note that a label may possibly have a combination of identifiers associated with it, such as a serial number, a barcode and an embedded RFID identifier. This would generate three nameTags for the one physical label, two of type 'label' for the barcode and serial number and one of type 'tagged' for the RFID identifier. intrinsic Identification technologies where the intrinsic properties of the component to be identified contain the identification information and no other unique code has been added. For example, some magnetic identification technologies use grooves machined into a component. Some components may also be identified, for example, by their individual sonic signature or optical profile. stamped An identification code physically stamped into the base material of the component to be identified. Note that if a serial number is stamped into a label attached to a component, 'labeled' should be used and not 'stamped'. Stamped identifiers can wear off but can not fall off. painted Painted or stenciled on the material. temporary Temporary identification codes marked with grease pencil, chalk, or such. unknown The value is not known. This value should not be used in normal situations. All reasonable attempts should be made to determine the appropriate value. Use of this value may result in rejection in some situations.

WITSML constant tool face An algorithm used to design a well trajectory during the planning stage minimum curvature An algorithm used to calculate the well trajectory spatial position (X,Y,Z) at execution stage or planning stage. The assumed path between stations is that of a circular arc in 3-D space. Also known as "Minimum Radius Of Curvature" method. tangential An algorithm used to calculate the well trajectory spatial position (X,Y,Z) at execution stage or planning stage. The assumed path between stations is a straight line oriented according to the seconds stations orientation.

The assumed path between stations is along two straight lines, with the first section oriented according to the first stations orientation and the second line oriented according to the second stations orientation. Each line segment is set to have a length of half the measured depth difference between the two stations. Also known as "Acceleration", "Secant", "Trapezoidal", and "Vector Averaging" methods. average angle An algorithm used to calculate the well trajectory spatial position (X,Y,Z) at execution stage or planning stage.
