WITSML Element Types The name of the coordinate reference system in a particular naming system. An optional short name (code) can also be specified. Specifying a well known system is highly desired. An example would be to specify a name of 'WGS 84 / UTM zone 10N' with a code of '32610' in the 'EPSG' naming system.

There are not specifications on how to form this name. A name assigned to a prospect - a well that has not yet been drilled. 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 geographic system this is commonly the name of the datum. Each well CRS can only represent only one type of system. Note that these structures do not truly define a CRS but rather specify information that could be used to describe a CRS. Map projection system. Geographic system. Local (engineering) system. A textual description of the system. The unique identifier of the system. Defines the datums associated with elevation, vertical depth and measured depth coordinates within the context of a well. 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). 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. 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. 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 the reference datum.

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.

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). The intended abstract supertype of all enumerated "types". This abstract type allows the maximum length of a type enumeration to be centrally defined.

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 leakoff test is usually conducted immediately after drilling below a new casing shoe. During the test, the well is shut in and fluid is pumped into the wellbore gradually to increase the pressure that the formation experiences. If the formation is not able to withstand the given pressure, the result of the test is the strength of the formation. Defines the class of a drilling fluid. A drilling fluid in which water is the continuous phase. A drilling fluid in which oil is the continuous phase. A drilling fluid in which neither water nor oil is the continous phase. The reading was measured. The reading was estimated. Personnel injury in connection with drilling and/or drilling related operations. Operation failed to achieve objective. Formation fluid invading the well bore. Circulation lost to the formation. Circulation impossible due to plugging or failure of equipment. Equipment got stuck in the hole. Equipment failure occurred.

An inner core barrel that that seals off the core sample using gel as the sealing material. An inner core barrel made of glass fiber reinforced plastic. A test to determine the productive capacity, pressure, permeability or extent (or a combination of these) of a hydrocarbon reservoir, with the drillstring still in the hole. A test to determine the daily rate of oil, gas, and water production from a (potential) reservoir. A preliminary report that has not yet been approved by the drilling operator. This report is normally issued at the beginning of the work day (e.g., 6:00 am) before A normal daily staus report that has been approved by the drilling operator. A report that represents the final definitive status for the well. This report is normally issued some period of time (e.g., 6 months) after the completion of drilling.

A well killing procedure that is prescribing pumping of kill weight fluid down the tubing and forcing the wellbore fluids back into the formation through the perforations. A well killing procedure that is prescribing to pump a volume of killing fluid corresponding to half the volume of the well tubing into the well, observing the well for 30 - 60 minutes and wait for the tubing head pressure to drop, then pump additional killing fluid into the well and when the wellhead pressure does not exceed 200 psi above observed tubing head pressure bleed off gas from the tubing at high rate. A well killing procedure that is prescribing a drilling fluid circulation down the tubing, through a circulation device (or out the end of a work string/coiled tubing) and up the annulus.

This is a variation of planeAngleMeasure with an attribute defining the direction of north. The unit of measure of the azimuth value. Specifies the direction to be considered North for the y axis. A unitless quantity. This should not be confused with a dimensionless measure. 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.

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). The version of the schema. The first three levels are fixed. The fourth level can vary to represent on the constraints defined in enumerations and XML loader files. The name of something within a naming system.
