WITSML Location Component Schema This is a location that is expressed in terms of 2D coordinates. In order that the location be understood, the coordinate reference system (CRS) must be known. The survey location is given by a pair of tagged values. The pairs may be: (1) latitude/longitude, (2) easting/northing, (3) westing/southing, (4) projectedX/projectedY, or (5) localX/localY. The appropriate pair must be chosen for the data. Modified-in-version=1.4.0, By-issue=1.3.1-110, Change=Modified-description A pointer to the wellCRS that defines the CRS for the coordinates. While optional, it is strongly recommended that this be specified. The latitude with north being positive. The longitude with east being positive. The projected coordinate with east being positive. This is the most common type of projected coordinates. UTM coordinates are expressed in Easting and Northing. The projected coordinate with north being positive. This is the most common type of projected coordinates. UTM coordinates are expressed in Easting and Northing. The projected coordinate with west being positive. The positive directions are reversed from the usual Easting and Northing values. These values are generally located in the southern hemisphere, most notably in South Africa and Australia. The projected coordinate with south being positive. The positive directions are reversed from the usual Easting and Northing values. These values are generally located in the southern hemisphere, most notably in South Africa and Australia. The projected X coordinate with the positive direction unknown. ProjectedX and ProjectedY are used when it is not known what the meaning of the coordinates is. If the meaning is known, the Easting/Northing or Westing/Southing should be used. Use of this pair implies a lack of knowledge on the part of the sender. The projected Y coordinate with the positive direction unknown. ProjectedX and ProjectedY are used when it is not known what the meaning of the coordinates is. If the meaning is known, the Easting/Northing or Westing/Southing should be used. Use of this pair implies a lack of knowledge on the part of the sender. The local (engineering) X coordinate. The CRS will define the orientation of the axis. The local (engineering) Y coordinate. The CRS will define the orientation of the axis. Flag indicating (if "true" or "1") that this pair of values was the original data given for the location. If the pair of values was calculated from an original pair of values, this flag should be "false" (or "0"), or not present. A Comment, generally given to help the reader interpret the coordinates if the CRS and the chosen pair do not make them clear. 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.

The wellbore may be defined within the context of another well. A pointer the wellbore with which there is a relationship. A pointer to the well that contains the wellboreReference. This is not needed unless the referenced wellbore is outside the context of a common parent well. A reference to a rig within a wellbore. The wellbore may be defined within the context of another well. This value represents a foreign key from one node to another. A pointer to the rig with which there is a relationship. A pointer to the wellbore that contains the rigReference. This is not needed unless the referenced rig is outside the context of a common parent wellbore. A pointer to the well that contains the wellboreParent. This is not needed unless the referenced wellbore is outside the context of a common parent well. A common way for handling names of objects. An identifier type must include a Name. It may also include a NamingSystem, which gives meaning to the name. Modified-in-version=1.4.0, By-issue=1.3.1-33, Change=Added A human contextual name of a well. This should (hopefully) be unique within the context of the naming system. The naming system under which the well is defined. Knowledge of the naming system may allow the hame to be parsed for embeded information. 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. WITSML - Well Coordinate Reference System Component Schema. Note that this is intended for use with two dimensional coordinates. That does not prevent the use of a three dimensional CRS. It just means that only two coordinates will be specified in that 3D system. The veritcal coordinates are specified separately and, for 3D systems, one of the linked wellDatums should represent the vertical datum of that 3D system so that the height in the 3d system can be determined. Human recognizable context for the system. For a geodetic system this is commonly the name of the datum. Modified-in-version=1.4.0, By-issue=1.3-48, Change=Modified-description Map projection system. Note that these structures do not truly define a CRS but rather specify information that could be used to describe a CRS.

Modified-in-version=1.4.0, By-issue=1.3-48, Change=Added A reference to the coordinateReferenceSystems object representing the Geodetic (i.e., Geocentric or Geographic) system. Modified-in-version=1.4.0, By-issue=1.3-48, Change=Added Local (engineering) system. Note that these structures do not truly define a CRS but rather specify information that could be used to describe a CRS. Modified-in-version=1.4.0, By-issue=1.3.1-110, Change=Modified-description A textual description of the system. 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. Defines the vertical datums associated with elevation, vertical depth and measured depth coordinates within the context of a well. Modified-in-version=1.4.0, By-issue=1.3-48, Change=Modified-description The human understandable contextual name of the reference datum. The code value that represents the type of reference datum. This may represent a point on a device (e.g., kelly bushing) or it may represent a vertical reference datum (e.g., mean sea level). Modified-in-version=1.4.0, By-issue=1.3-48, Change=Added The name of the vertical reference datum in a particular naming system. This should only be specified if the above 'code' represents some variation of sea level. An optional short name (code) can also be specified. Specifying a well known datum is highly desired if the above code is a variant of sea level because sea level varies over time and space. An example would be to specify a name of 'Caspian Sea' with a code of '5106' in the 'EPSG' naming system. A reference to the coordinateReferenceSystem object representing the vertical reference datum (i.e., this wellDatum). This should only be specified if the above 'code' represents some variation of sea level. Modified-in-version=1.4.0, By-issue=1.3-48, Change=Added Since various activities may use different points as measurement datums, it is useful to characterize the point based on its usage. A well reference datum may have more than one such characterization. For example, it may be the datum used by the driller and logger for measuring their depths. Example usage values would be 'permanent','driller', 'logger' 'WRP' (well reference point) and 'SRP' (site reference point). A pointer to the wellbore that contains the reference datum. This should be specified if a measured depth is given. A pointer to the rig that contains the device used as a reference datum. The rig may be associated with a wellbore in another well (e.g., pattern drilling using a rig on a track). The gravity based elevation coordinate of this reference datum as measured from another datum. Positive moving upward from the elevation datum. An elevation should be given unless this is a vertical reference datum (e.g., sea level). The measured depth coordinate of this reference datum as measured from another datum. The measured depth datum should either be the same as the elevation datum or it should be relatable to the elevation datum through other datums. Positive moving toward the bottomhole from the measured depth datum. This should be given when a local reference is "downhole", such as a kickoff point or ocean bottom template, and the borehole may not be vertical. If a Depth is given then an Elevation should also be given. The horizontal location of the point being used as a well datum. This may be used when the point is not directly above or below the well point location. For example, a well being drilled from a platform may have its location at the entrance into the sea floor, while the well datum may be located on the drilling rig. Or the well datum may be a kickoff point, that is not directly under the well surface point. Modified-in-version=1.4.0, By-issue=1.3-48, Change=Added A contextual description of the well reference datum. True indicates that this is the default reference datum for measured depth coordinates. False or not given indicates that this is not the default reference datum. Measured depth coordinates that do not specify a datum reference should be assumed to be measured relative to this default reference datum. Only one reference datum may be designated as the default measured depth datum for each well. Values are "true" (or "1") and "false" ( or "0"). True indicates that this is the default reference datum for vertical depth coordinates. False or not given indicates that this is not the default reference datum. Vertical depth coordinates that do not specify a datum reference should be assumed to be measured relative to the default reference datum. Only one reference datum may be designated as the default vertical depth datum for each well. Values are "true" (or "1") and "false" ( or "0"). True indicates that this is the default reference datum for elevation coordinates. False or not given indicates that this is not the default reference datum. Elevation coordinates that do not specify a datum reference should be assumed to be measured relative to the default reference datum. Only one reference datum may be designated as the default elevation datum for each well. Values are "true" (or "1") and "false" ( or "0"). 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 WITSML API mandated plural root element which allows multiple singular objects to be sent. The plural name is formed by adding an "s" to the singular name.

Data object schema version. The fourth level must match the version of the schema constraints (enumerations and XML loader files) that are assumed by the document instance. Modified-in-version=1.4.0, By-issue=1.3.1-33, Change=Added Human recognizable context for the well that contains the wellbore. Human recognizable context for the wellbore that contains the drilling report. Human recognizable context for the drilling report. Date and time of the start of the reporting period. Date and time end of the reporting period. Report periods are commonly 24 hour periods. The kind of report version. For example, a preliminary version. The date and time of the report creation. A later timestamp indicates a newer version. In order to update values in a report a full updated copy of the original report should be submitted. An alternative name of the well (in a naming system). The above well name should be included in the list of aliases so that its origin can be known. An alternative name of the wellbore (in a naming system). The above well name should be included in the list of aliases so that its origin can be known. Defines a vertical datum used for measured depths, vertical depths or elevations. This must be specified if one of the aforementioned coordinate values are included in the report. This only applies to this report and is generally a copy of the same information from the well object. Defines a coordinate reference system used by coordinates within this report. This must be specified if coordinate values are included in the report (i.e., in a survey station location). This only applies to this report and is generally a copy of the same information from the well object. General information about a wellbore. The well is represented by the original wellbore. General status information. Information about a bit. One fluid record. Information about the pore pressure. A description of what happened from the end of report to an alternative time before the end of the next report. This is intended to allow a preliminary description of what happened from the end of the report (commonly midnight) until the time of submission of a preliminary report (commonly 6:00 in the morning). A survey station recorded during the report interval. Activity breakdown, multiple for many activities. General information about a log. General information about a core. General information about a production well test. General information about a wireline formation test. General information about the lithology and shows in an interval. General information about equipment failure. General information about a well control incident. General information about a well control incident. General information about a well control incident. General information about a gas reading. Unique identifier for the well. This uniquely represents the well referenced by the (possibly non-unique) nameWell. Unique identifier for the wellbore. This uniquely represents the wellbore referenced by the (possibly non-unique) nameWellbore. The unique identifier of an object. This should not be used for child nodes within an object. For an independent object, the value may be globally unique. For a dependent object, the value must be unique (for the same object type) within the context of the parent object. There should be no assumption as to the semantic content of this attribute. The purpose of this type is to facilitate modifying the optionality in derived schemas. This type disallows an "empty" boolean value. This type should not be used directly except to derive another type. All boolean types should be derived from this type rather than using xsd:boolen. This type disallows an "empty" dateTime value. This type should not be used directly except to derive another type. All dateTime types should be derived from this type rather than using xsd:dateTime. This type disallows an "empty" date value. This type should not be used directly except to derive another type. All dateTime types should be derived from this type rather than using xsd:dateTime. This type disallows an "empty" double value. This type should not be used directly except to derive another type. This type disallows an "empty" short value. This type should not be used directly except to derive another type. The intended abstract supertype of all strings. This abstract type allows the control over whitespace for all strings to be defined at a high level. This type should not be used directly except to derive another type. Replace tab, line feed and carriage return with a space, collapse contiguous sequences of spaces to a single space and then remove leading and trailing spaces. The empty string is not allowed. This constraint conbined with the whiteSpace collapse constraint means that a blank value is not allowed. The intended abstract supertype of all quantities that have a value with a unit of measure. The unit of measure is in the uom attribute of the subtypes. This type allows all quantities to be profiled to be a 'float' instead of a 'double'. This defines the maximum acceptable length of a string that can be stored in a data base. This value should be the smallest "maximum size of a variable length character type" in commonly used DBMSs. This is the maximum size of a VARCHAR2 in Oracle 8. A positive integer (one based count or index) with a maximum value of 32767 (2-bytes). This value cannot be negative or zero. The intended abstract supertype of all user assigned human recognizable contextual name types. 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. The intended abstract supertype of all locally unique identifiers. 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). Spaces are not allowed. The intended abstract supertype of all comments or remarks intended for human consumption. There should be no assumption that semantics can be extracted from the 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. Modified-in-version=1.4.0, By-issue=1.3.1-33, Change=Added A 32 character string. Modified-in-version=1.4.0, By-issue=Bug, Change=Added The intended abstract supertype of all enumerated "types". This abstract type allows the maximum length of a type enumeration to be centrally defined. This type should not be used directly except to derive another type. It should also be used for uncontrolled strings which are candidates to become enumerations at a future date. The intended abstract supertype of all "units of measure". This abstract type allows the maximum length of a UOM enumeration to be centrally defined. This type is abstract in the sense that it should not be used directly except to derive another type. The north direction as defined by the magnetic north pole at the time of the measurement. The magnetic north pole is the direction that a magnet will point to when freely rotating. The north direction is defined by the coordinate grid in the projection coordinate system. The north direction as defined by the true north pole. The true north pole is an average of the actual measured north axis, which is the axis of rotation of the earth. The type of local or permanent reference datum for vertical gravity based (i.e., elevation and vertical depth) and measured depth coordinates within the context of a well.

The original wellbore had to be abandoned before its final usage. This wellbore is being drilled as a different wellbore, but one which has the same target as the one that was abandoned. This is the first wellbore that has been drilled, or attempted, in a given well. The wellbore is being redrilled. The wellbore is being reentered after a period of abandonment. The wellbore is part of an existing regulatory well. The original borehole did not reach the target depth. This borehole required the well to be respudded (drilled from a different surface position). The wellbore is a deviation from a given wellbore, that produces a different borehole from the others, and whose bottomhole differs from any previously extisting wellbore bottomholes. A julian date. A date with a time of day and a mandatory time zone offset. This must captute the correct date-time relative to UTC. It is not necessary to use a local time zone because software may convert the date-time to a different local time zone (while retaining correct date-time relative to UTC). See acquisitionTmeZone in commonData for the original time zone of times in an object. Modified-in-version=1.4.0, By-issue=1.3.1-39, Change=Modified-description Modified-in-version=1.4.0, By-issue=1.3.1-39, Change=Modified-constraint Values of "true" (or "1") and "false" (or "0"). The angle of a Y axis from North. This is a variation of planeAngleMeasure with an attribute defining the direction of north. Modified-in-version=1.4.0, By-issue=1.3.1-110, Change=Non-semantic The unit of measure of the azimuth value. Modified-in-version=1.4.0, By-issue=1.3.1-86, Change=Changed-type-from:planeAngleUom Specifies the direction to be considered North for the y axis. A volume per volume measure that is constrained to a unit of percent. Modified-in-version=1.4.0, By-issue=1.3.1-110, Change=Non-semantic A unitless quantity. This should not be confused with a dimensionless measure. A locally unique identifier. The value is not intended to convey any semantic content (e.g., it may be computer generated). Modified-in-version=1.4.0, By-issue=1.3.1-5, Change=Modified-description A unique identifier of an object parent. This should only be used for the uid of a parent object (i.e., a foreign key to another object). It should not be used for child nodes of an object. The value is not intended to convey any semantic content (e.g., it may be computer generated). The purpose of this type is to facilitate modifying the optionality of parentage uids in derived schemas. Modified-in-version=1.4.0, By-issue=1.3.1-5, Change=Added A reference to a name in another node of the xml hierachy. This value represents a foreign key from one element to another. 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. Modified-in-version=1.4.0, By-issue=1.3.1-33, Change=Changed-type-from:abstractString 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.

The naming system within the name is unique. A unique (short) code associated with the name. A geodetic zone with values from 1 to 60 and a required direction of "N" (North) or "S" (South). For example, "21N". A measured depth coordinate in a wellbore. Positive moving from the reference datum toward the bottomhole. 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 unit of measure of the quantity value.

If not given then the default WellDatum must be assumed. A vertical (gravity based) depth coordinate within the context of a well. Positive moving downward 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 unit of measure of the quantity value. A pointer to the reference datum for this coordinate value as defined in WellDatum. If not given then the default WellDatum must be assumed. 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 unit of measure of the quantity value. If not given then the default unit of measure of the explicitly or implicitly given datum must be assumed. A pointer to the reference datum for this coordinate value as defined in WellDatum. If not given then the default WellDatum must be assumed. A positive integer (one based count or index). This value cannot be negative or zero.
