Documents submitted in support of a regulatory submission. A datum to which elevations and depths are referenced. A coordinate reference system that was used within the context of this well. 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 - 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. The preferred method of contacting a business associate. Postal mail at the business address. Business fax. Business email. Postal mail at the business address. Business voice phone. Mobile phone. Pager. Personal fax. Personal email. Postal mail at the personal address. Personal voice phone. WITSML - Custom or User Defined Element and Attributes Component Schema. Specify custom element, attributes, and types in the custom data area. Any element or attribute in any namespace. It is strongly recommended that all custom data definitions be added to a unique namespace. The decimal diameter value and unit of measure. If numerator and denominator are specified then this should be a whole number. The actual diameter is this value summed with the numerator divided by the denoninator. That is, value+(numerator/denominator). If a unit conversion is performed then the numerator and denominator can be eliminated because they would probably not make sense in the new unit of measure. For values which may have been originally defined using a fractional part that is a ratio, this specifies the numerator of that ratio. The unit of measure is assumed to be defined by the decimal value. If a unit conversion is performed then the numerator and denominator can be eliminated because they would probably not make sense in the new unit of measure. If numerator is specified then the denominator must also be specified. For values which may have been originally defined using a fractional part that is a ratio, this specifies the denominator of that ratio. The unit of measure is assumed to be defined by the decimal value. If a unit conversion is performed then the numerator and denominator can be eliminated because they would probably not make sense in the new unit of measure. If denominator is specified then the numerator must also be specified. A schema to capture a set of data that is relevant for many exchange documents. It includes information about the file that was created, and high-level information about the data that is being exchanged within the file. An identifier for the document. This is intended to be unique within the context of the NamingSystem. Zero or more alternate names for the document. These names do not need to be unique within the naming system. The date of the creation of the document. This is not the same as the date that the file was created. For this date, the document is considered to be the set of information associated with this document information. For example, the document may be a seismic binset. This represents the date that the binset was created. The FileCreation information would capture the date that the XML file was created to send or exchange the binset. A document class. Examples of classes would be a metadata classification or a set of keywords. The information about the creation of the exchange file. This is not about the creation of the data within the file, but the creation of the file itself. Information about the security to be applied to this file. More than one classification can be given. A free-form string that allows a disclaimer to accompany the information. A collection of events that can document the history of the data. The owner of the data. An optional comment about the document. A block of information about the creation of the XML file. This is different than the creation of the data that is included within the file. The date and time that the file was created. If appropriate, the software that created the file. This is a free form string, and may include whatever information is deemed relevant. The person or business associate that created the file. Any comment that would be useful to further explain the creation of this instance document. Information about the security classification of the document. 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. The date on which this security class is no longer applicable. A general comment to further define the security class. The audit records what happened to the data, to produce the data that is in this file. It consists of one or more events. An event type captures the basic information about an event that has affected the data. The date on which the event took place. The party responsible for the event. A free form comment that can further define the event that occurred. An email address with an attribute, used to "qualify" an email as personal, work, or permanent. An general address structure. This form is appropriate for most countries. The Name line of an address. If missing, use the Name of the business associate. The Street is a generic term for the middle lines of an address. They may be a street address, PO Box, Suite number, or any lines that come between the "name" and "city" lines. This may be repeated for up to four, ordered lines. The City for the business associate's address The GeneralAddress allows the choice of a State, Province, or County element. It is assumed that different elements would be appropriate in different countries. A user community should choose which element is appropriate in the various countries. The Country may be included. Although this is optional, it is probably required for most uses. A postal code, if appropriate for the country. In the USA this would be the five or nine digit zip code. The type of address: mailing, physical, or both. The unique identifier of the recurring node. Kind of Address. The mailing address of a business associate or facility. The physical address - location - of a business associate or facility. Both the mailing address and the physical address. WITSML - Geodetic Model Component Schema 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 'ED50' with a code of '4230' in the 'EPSG' naming system. Note that specifying a name in the EPSG naming system is asserting that the parameters in the EPSG database are appropriate for this CRS. This is also true for any other naming system. If in doubt, contact your local geodesist. Geodetic datum code. This defines a system in the Geoshare naming system and should probably not be used with CRSName. Ellipsoid translation (3). Units are meters by convention. Ellipsoid translation (3). Units are meters by convention. Ellipsoid translation (3). Units are meters by convention. Ellipsoid rotation (3). Seconds of arc by convention. Ellipsoid rotation (3). Seconds of arc by convention. Ellipsoid rotation (3). Seconds of arc by convention. Ellipsoid scale factor.

Implied if geodeticDatumCode or ellipsoidCode specified. Ellipsoid inverse flattening value (ie. 1/x). Implied if geodeticDatumCode or ellipsoidCode specified. 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. Since Names and NamingSystems may change with time, it may also include a Version, to further refine the meaning of the name. Note that this three-part structure is based on the ISO Identifier type. The name of the object being identified. It may or may not be a unique name, depending on the use of this type. When used as an "identifier," it should be a unique name, within the naming system. When used as an "alias," the name is not required to be unique. The naming system under which the name is defined. For example, if the name is a person's social security number, the naming system would be SSN, or some equivalent code which represents that the name is a social security number. Since naming system may be a code, there are two attributes (nameRef and systemList), which may be used to lead an application to a registry, where meaning can be obtained for the code. A comment about the identifier. The unique identifier of the recurring node. True ("true" or "1") indicates that the well surface point is the origin of this CRS. False ("false" or "0") or not given indicates otherwise. A pointer to the reference point that is the origin of this CRS. A textual description of the origin. The angle of the Y axis from North (as described in attribute northDirection). Defaults to zero. Positive clockwise. A free-form description of the Y axis. Examples would be 'parallel to the west side of the platform', or 'along the main entry road'. True ("true" or "1") indicates that the X axis is rotated counter-clockwise from the Y axis when viewed from above the earth looking down. False ("false" or "0") or not given indicates a clockwise rotation. Generally the X axis is rotated clockwise. 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. A pointer to the wellCRS that defines the CRS for the coordinates. While optional, it is strongly recommended that this be specified. 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. 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. The accuracy of the horizontal 2D positional or GPS readings. The percent dilution of precision ("PDOP"). Measure of the geometrical strength of the GPS satellite configuration. The amount of error in the position. PDOP less than 4 gives the best accuracy (under 1 meter). Between 4 and 8 gives acceptable accuracy. Greater than 8 gives poor accuracy. Method of determining the horizontal 2D location. 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 the location. The letter associate with the cell (quad) in a Carter land grid. A letter represents 5 minutes of latitude. The number associate with the cell (quad) in a Carter land grid.

The persons last or given name. A name suffix. Such as Esq, Phd, etc. A phone number with two attributes, used to "type" and "qualify" a phone number. The type would carry information such as fax, modem, voice, and the qualifier would carry information such as home or office. The kind of phone such as voice or fax. Indicates whether the number is personal, business or both. The phone number extension. One method of characterizing a phone number. The telephone number is a conventional number which is used for voice contact. The telephone number is exclusively used for receiving faxes. The telephone number is a mobile telephone, such as a cell phone. The telephone at this number is capable of voice communication and of receiving faxes. The telephone is connected directly to voice mail. A voice phone may lead a caller to voice mail. However this choice qualifies the phone type as being only voice mail. The telephone is intended only for pages. 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. Note that specifying a name in the EPSG naming system is asserting that the parameters in the EPSG database are appropriate for this CRS. This is also true for any other naming system. If in doubt, contact your local geodesist. A code to identify the type of projection. A pointer to the wellCRS that represents the geographic system from which this system was projected.

Free format will allow for entries such as NESW (southwest quarter of northeast quarter), E2NESE (southeast quarter of northeast quarter of east half), CNE (northeast quarter of center quarter), etc. Quarter township. Distance inside of the boundary line of the specified section. North specifies the distance from the north boundary line. Distance inside of the boundary line of the specified section. East specifies the distance from the east boundary line. Data that represents a foreign key to a wellbore. The wellbore may be defined within the context of another well. A pointer to the wellbore with which there is a relationship. A pointer to the well that contains the wellboreReference.

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. 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 embedded information. Unique identifier for the element. The path of the centerline of a wellbore through the subsurface.

Hole inclination, measured from vertical. Hole azimuth. Corrected to wells azimuth reference. Distance along vertical section azimuth plane. Dogleg severity. The 2D coordinates of the station. Unique identifier for the recurring item. 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.

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.

Hardened steel or tungsten hollow blades arranged around the drill bit are used to bore a hole into rock. The blades contain an inner tube which sits inside the hollow outer rod barrel. The drill cuttings are removed by injection of compressed air into the hole via the hollow inner rod. Drilling is done with a helical screw which is driven into the ground with rotation; the earth is lifted up the borehole by the blade of the screw. A traditional way of drilling small-bore wells. Commonly called "spudders", these rigs raise and drop the bit to finely crush the rock surface. Then the bit is raised and a bail is lowered; if the borehole is dry, water is added. The bail receives the water and rock fragments, then closes, allowing them to be raised and removed. The bit is again lowered until contact is made with the rock surface, upon which it is again raised and dropped until additional bailing is possible. A drilling method that uses an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock. A method of drilling generally limited to shallow soil sample recovery in clay or silty soils wherein a hollow core sampling bit and rod are pushed directly into the soil with hydraulic rams. A method of drilling that uses three-cone roller, fixed-cutter diamond, or diamond-impregnated drill bits to wear away at the cutting face. Rotating hollow drill pipes carry down bentonite and barite impregnated drilling muds to lubricate, cool, and clean the drilling bit. A pneumatic reciprocating piston is used to energetically drive a heavy drill bit into the rock. The drill bit is hollow, solid steel and has ~20 mm thick tungsten rods protruding from the steel matrix as 'buttons'. The tungsten buttons are the cutting face of the bit. The cuttings are blown up the outside of the rods and collected at surface. Air or a combination of air and foam are used to lift the cuttings. The drilling mechanism is a pneumatic reciprocating piston, known as a 'hammer,' driving a tungsten-steel drill bit. High-frequency resonant vibrations are sent down the drill string to the drill bit, while the operator controls these frequencies to suit the specific conditions of the soil/rock geology. Resonance magnifies the amplitude of the drill bit, which fluidizes the soil particles at the bit face. The value is not known. This value should not be used in normal situations.

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. This value is assumed to match the uid value in a WellDatum. 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) 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. The units of measure that are valid for vertical gravity based coordinates (i.e., elevation or vertical depth) within the context of a well. meter International Foot US Survey Foot British Foot 1865 A non-negative integer (zero based count or index) with a maximum value of 32767 (2-bytes). For items that represent "number of" something or a "sequential" count or index. This value can be zero but cannot be negative. A positive integer (one based count or index). This value cannot be negative or zero. A large positive integer (one based count or index) with a maximum value of 2,147,483,647 (4-bytes). This value cannot be negative or zero. Indexes things with the same name. That is the first one, the second one, etc. A community assigned human recognizable short name. This type of value is intended to be unique and is generally a candidate to be constrained to an enumerated list. The angle of a Y axis from North. This is a variation of planeAngleMeasure for the purpose of defining compass directions. The directions are not restricted to being from north. The unit of measure of the angle value. Specifies the direction to be considered North. Specifies the compass direction of the origin and the direction of the angle from that origin. Designates a particular quarter of a township. Some combination of NE,NW,SW,SE,N2,S2,E2,W2,C,TRxx,LTnn. "A" through "Z" or "AA" through "GG".( "0" through "92".( "1" through "25".( The distance to a one minute boundary on the north or south of a point. The unit of measure of the distance value. Specifies the reference line that is the origin of the distance. The distance to a one minute boundary on the east or west of a point. The unit of measure of the distance value. Specifies the reference line that is the origin of the distance. Sections are numbered "1" through "36." Irregular sections may be designated with a single value after a decimal point.
