The unique identifier of a container element. This attribute is generally required within the context of a WITSML server. There should be no assumption as to the semantic content of this attribute. This should only be used with recurring container types (i.e., maxOccurs greater than one). The value is only required to be unique within the context of the nearest recurring parent element. The business associate describes any company, person, group, consultant, etc, which is associated within a context (e.g., a well). The information contained in this module is: (1) contact information, such as address, phone numbers, email, (2) alternate name, or aliases, and (3) associations, such as the business associate that this one is associated with, or a contact who is associated with this business associate. The name of the business associate. This can be the name of a person, business, group, etc. The role of the business associate within the context. For example, "driller" or "operator", "lead agency - CEQA compliance" "regulatory contact", "safety contact". A business associate will generally have one role but the role may be called different things in different naming systems. If the business associate is a person, this specifies the component names of the person. The alias is an alternate name of a business associate. It is generally associated with a naming system. An alias is not necessarily unique within the naming system. Note that address may occur more than once, because it may be necessary to give a physical address, a mailing address, or both. The various types of phone numbers may be given. The may be office or home, they may be a number for a cell phone, or for a fax, etc. Attributes of PhoneNumber declare the type of phone number that is being given. The email address may be home, office, or permanent. More than one may be given. The preferred method of being contacted within the context of this role. A pointer to another business associate that this business associate is associated with. The most common situation is that of an employee being associated with a company. But it may also be, for example, a work group associated with a university. A pointer to a business associate (generally a person) who serves as a contact for this business associate. The count of the number of personnel in a group. A general comment. This should not be used to carry semantic information. This is not intended to be machine interpretable. Unique identifier for the business associate. WITSML - Common Data Component Schema An identifier to indicate the data originator. This identifies the server that originally created the object and thus most of the uids in the object (but not necessarily the uids of the parents). This is typically a url. When the data was created at the persistent data store. Last change of any element of the data at the persistent data store. The change time is not updated for a growing object while it is growing. The item state for the data object. Comments and remarks. WITSML - Product Flow Connected Node Component Schema. Defines the node to which this port is connected. Only two ports should be actively connected to the same node at the same point in time. That is, a port should only be connected to one other port. There are no semantics for the node except common connection. All ports that are connected to a node with the the same name are inherently connected to each other. The name of the node is only required to be unique within the context of the current Product Flow Network (that is, not the overall model). All ports must be connected to a node and whether or not any other port is connected to the same node depends on the requirements of the network. Any node that is internally connected to only one node is presumably a candidate to be connected to an external node. The behavior of ports connected at a common node is as follows: a) There is no pressure drop across the node. All ports connected to the node have the same pressure. That is, there is an assumption of steady state fluid flow. b) Conservation of mass exists across the node. The mass into the node via all connected ports equals the mass out of the node via all connected ports. c) The flow direction of a port connected to the node may be transient. That is, flow direction may change toward any port if the relative internal pressure of the Product Flow Units change and a new steady state is achieved. The name of a network plan. This indicates a planned connection. The connected port must be part of the same plan or be an actual. Not specified indicates an actual connection.

The value of a dependent (data) variable in a row of the curve table. The units of measure are specified in the curve definition. The first value corresponds to order=1 for columns where isIndex is false. The second to order=2. And so on. The number of index and data values must match the number of columns in the table. The definition of a curve. The order of the value in the index or data tuple. If isIndex is true this is the order of the (independent) index element. If isIndex is false, this is the order of the (dependent) value element. The name of the variable in this curve. True (equal "1" or "true") indicates that this is an independent variable in this curve. At least one column column should be flagged as independent. The measure class of the variable. This defines which units of measure are valid for the value. The unit of measure of the variable. The unit of measure must match a unit allowed by the measure class. Unique identifier for the port.

This is intended as a documentation of the security so that the file will not inadvertently be sent to someone who is not allowed access to the data. This block also carries a date that the security classification expires. For example, a well log is confidential for a period of time, and then becomes open. All security classes are characterized by their classification systems. The security class in which this document is classified. Examples would be confidential, partner confidential, tight. The meaning of the class is determined by the System in which it is defined. The security classification system. This gives context to the meaning of the Class value.

Calibration parameters vary from vendor to vendor, depending on the calibration method being used. This is an extension of the general cs_dtsCalibration, and allows for specific parameters associated with an instrument box. The two additional parameters are the offset temperature calibration, and the slope calibration. These allow for a linear shift in temperature vs measurements. Additional offset and slope calibrations may be performed at measurement time. The date of the calibration The business associate that performed the calibration.

The reported wavelength should be the wavelength of the light in a vacuum. Unique identifier for the loss. This records the result arrays, along with context information, from an Optical Time Domain Reflectometry (OTDR) run. The arrays will define the relative scattered power from the Rayleigh scattering vs distance along the fiber. The actual data values are recorded in a wellLog object, which is referenced in a subelement. The reason the OTDR test was run. The three main reasons are 'pre-installation', which is before the installation of the fiber; 'post-installation', which is used to validate a successful fiber installation; and 'DTS run', which is a quality check of the fiber prior to a DTS run.

WITSML - Equipment NameTag Schema The physical identification string of the equipment tag. The format or encoding specification of the equipment tag. The tag may contain may different pieces of information and knowledge of that information is inherent in the specification. The "identification string" is a mandatory part of the information in a tag. Identifies the general type of identifier on an item. If multiple identifiers exist on an item, a separate description set for each identifier should be created. For example, a joint of casing may have a barcode label on it along with a painted-on code and an RFID tag attached or embedded into the coupling. The barcode label may in turn be an RFID equipped label. This particular scenario would require populating five nameTags to fully describe and decode all the possible identifiers as follows: 'tagged' - RFID tag embedded in the coupling, 'label' - Serial number printed on the label, 'tagged' - RFID tag embedded into the label, 'label' - Barcode printed on the label, 'painted'- Mill number painted on the pipe body. An indicator of where the tag is attached to the item. This is used to assist the user in finding where an identifier is located on an item. This optional field also helps to differentiate where an identifier is located when multiple identifiers exist on an item. Most downhole components have a box (female thread) and pin (male thread) end as well as a pipe body in between the ends. Where multiple identifiers are used on an item, it is convenient to have a reference as to which end, or somewhere in the middle, an identifier may be closer to. Some items may have an identifier on a non-standard location, such as on the arm of a hole opener. 'other', by exclusion, tells a user to look elsewhere than on the body or near the ends of an item. Most non-downhole tools will use either 'body', 'other' or not specified as the location tends to lose value with smaller or non threaded items. When the tag was installed in or on the item. The name of the company that installed the tag. Reference to a manufacturers or installers installation description, code, or method. A comment or remark about the tag. Unique identifier for the tag. A type of offshore location that captures the North Sea Offshore terminology.

Defines the expected flow and product pairs to be assigned to this port by a Product Volume report. A set of expected qualifiers can be defined for each pair. The aggregate of expectations on all properties should be a subset of the aggregate of expectations on the port. If no expectations are defined on the port then the port aggregate will be defined by the properties. A descriptive remark associated with this property. The unique identifier of the recurring element. Defines expected properties of a facility represented by a unit. The expected kind of facility property. Each property is documented to have values of a particular type. The expected kind of qualifier of the property. A descriptive remark associated with this property.

This also defines the kind of facility. The unique identifier of the recurring element. WITSML - Product Flow Network External Port Component Schema. The name of the external port within the context of the current Product Flow Network. Defines whether this port is an inlet or outlet. Note that this is a nominal intended direction. True ("true" or "1") indicates that the port is an exposed internal port and cannot be used in a connection external to the network. False ("false" or "0") or not given indicates a normal port. Defines the internal node to which this external port is connected. All ports (whether internal or external) that are connected to a node with the same name are connected to each other. Node names are unique to each network. The purpose of the external port is to provide input to or output from the internal network except when the port is an "exposed" port. The purpose of an exposed port is to allow the properties of the port to be seen external to the network. For an exposed port, the connection points to the associated port. A descriptive remark about the port. Unique identifier for the port. The non-contextual content of a WITSML Product Flow Network object. The name of the Product Flow Network. This must be unique within the context of the overall Product Flow Model. The name of a network plan. This indicates a planned network. All child network components must all be planned and be part of the same plan. The parent network must either contain the plan (i.e., be an actual) or be part of the same plan. Not specified indicates an actual network. A pointer to the network containing the unit that this network represents. That is, the Unit must exist in a different Network. If a parent network is not specified then the network represents the model. A model should only be represented by one network. The model network represents the overall installation. All other networks represent internal detail and should not be referenced from outside the model. The external ports on the model network represent the external ports to the overall Product Flow Model. A pointer to an external port on the Product Flow Model does not require the name of the model network because it is redundant to knowledge of the model name (i.e., there is a one-to-one correspondence). DEPRECATED. Use parentNetwork for all new work. A pointer to the Flow Unit that this network represents. The Unit must exist in a different Network. If a unit is not specified then the network represents the model. A model should only be represented by one network. The model network represents the overall installation. All other networks represent internal detail and should not be referenced from outside this model. The external ports on the model network represent the external ports to the overall Product Flow Model. A pointer to an external port on the Product Flow Model does not require the name of the model network because it is redundant to knowledge of the model name (i.e., there is a one-to-one correspondence). A unit model defines the internal behavior of a Flow Unit. A descriptive remark about the network. An external port. This exposes an internal node for the purpose of allowing connections to the internal behavior of the network. Networks that represent a Flow Unit should always have external ports. If this network represents a Unit then the name of the external port must match the name of a port on the Unit (i.e., they are logically the same port). A flow behavior for one unit. Within this context, a unit represents a usage of equipment for some purpose. The unit is generally identified by its function rather than the actual equipment used to realize the function. A unit might represent something complex like a field or separator or something simple like a valve or pump. Documents that a change occurred at a particular time. Unique identifier for the network. WITSML - Product Flow Port Component Schema. The name of the port within the context of the Product Flow Unit. The name of a network plan. This indicates a planned port. All child network components must all be planned and be part of the same plan. The parent unit must be part of the same plan or be an actual. Not specified indicates an actual port. Defines whether this port is an inlet or outlet. This is a nominal intended direction. The name of the facility represented by this Product Flow Port The name can be qualified by a naming system. The facility name is assumed to be unique within the context of the facility represented by the unit. This also defines the kind of facility. An alternatative name of a facility. This is generally unique within a naming system. The above contextually unique name should also be listed as an alias. True ("true" or "1") indicates that the port is an exposed internal port and cannot be used in a connection external to the unit. False ("false" or "0") or not given indicates a normal port. Defines the node to which this port is connected. A timestamp activates and deactivates the connection. Only one connectedNode should be active at any one point in time. There are no semantics for the node except common connection. All ports that are connected to a node with the the same name are inherently connected to each other. The name of the node is only required to be unique within the context of the current Product Flow Network (that is, not the overall model). All ports must be connected to a node and whether or not any other port is connected to the same node depends on the requirements of the network. Any node that is internally connected to only one port is presumably a candidate to be connected to an external node. The behavior of ports connected at a common node is as follows: a) There is no pressure drop across the node. All ports connected to the node have the same pressure. That is, there is an assumption of steady state fluid flow. b) Conservation of mass exists across the node. The mass into the node via all connected ports equals the mass out of the node via all connected ports. c) The flow direction of a port connected to the node may be transient. That is, flow direction may change toward any port(s) if the relative internal pressure of the Product Flow Units change and a new steady state is achieved.

The meaning of the endpoint of an interval can be modified by the endpoint attribute. The default is "inclusive". A date value used for min/max query parameters related to "growing objects". The meaning of the endpoint of an interval can be modified by the endpoint attribute. The default is "inclusive". An email address with an attribute, used to "qualify" an email as personal, work, or permanent. Identifies a facility. The kind of facility. The naming system within which the name is unique. For example, API or NPD. If the facility is defined and instantiated within the context of a WITSML server, this is a pointer to the uid value of that object instance.

This attribute is required within the context of a WITSML server. A reference to a wellDatum in the current well. This value must match the uid value in a WellDatum. This value represents a foreign key from one element to another. This is an exception to the convention that a foreign key must utilize both a human contextual name and a uid value. For messages outside the context of a server then this value will commonly match the value of the name of the wellDatum (e.g., 'KB') if uids are not not used in that context. This was a compromise in order to allow the coordinate structures to be simple and still be usable both within the context of a server and outside the context of a server. A user assigned human recognizable contextual name of something. There should be no assumption that (interoperable) semantic information will be extracted from the name by a third party. This type of value is generally not guaranteed to be unique and is not a candidate to be replaced by an enumeration. A comment or remark intended for human consumption. There should be no assumption that semantics can be extracted from this field by a computer. Neither should there be an assumption that any two humans will interpret the information in the same way (i.e., it may not be interoperable). A textual description of something. A community assigned human recognizable name. This type of value is intended to be unique and is generally a candidate to be constrained to an enumerated list. A unit of measure acronym from the POSC unit of measure file. A locally unique identifier. The value is not intended to convey any semantic content (e.g., it may be computer generated). The value is only required to be unique within a context in a document (e.g., defined via key and keyref). There is no guarantee that the same data in multiple documents will utilize the same uid value unless enforced by the source of the document (e.g., a document server). A reference to the unique identifier of another element. This value represents a foreign key from one element to another. The value should match the value of an attribute of type uidString. The version of the schema. The first three levels are fixed. The fourth level can vary to represent the constraints defined in enumerations and XML loader files.

If not given then the default WellDatum must be assumed. The units of measure that are valid for measured depths in a wellbore. meter International Foot US Survey Foot A vertical (gravity based) elevation coordinate within the context of a well. Positive moving upward from the reference datum. All coordinates with the same datum (and same uom) can be considered to be in the same Coordinate Reference System and are thus directly comparable.

The standard conditions must be known outside the context of the data type because the unit of measure is independent of the standard conditions. The main intent of this type is to allow programatic determination of where standard conditions are assumed. A ratio of an uncorrected volume to a volume corrected to standard conditions of temperature and pressure. The standard conditions must be known outside the context of the data type because the unit of measure is independent of the standard conditions. The main intent of this type is to allow programatic determination of where standard conditions are assumed. A ratio of volumes that have each been corrected to standard conditions of temperature and pressure. The standard conditions must be known outside the context of the data type because the unit of measure is independent of the standard conditions.
