1 IntroductionThe intention of this document is to provide a simplified description of the semantics in version 1.1 of the standard XML schema for daily drilling reporting on the Norwegian Continental Shelf. The taxonomy of drilling reporting concepts included in the POSC Caesar (PCA) Reference Data System (RDS) is reproduced in a tabular format, where specializations between concepts is indicated by indentation. In addition, the concepts class names in the RDL, the PCA unique reference ID and the concept definitions are included.

2 About the Daily Drilling Report

2.1 Overall pictureAs of October 1st 2009 it will be possible to distribute daily drilling reports on XML format to license partners via Licensesweb. Both XML documents (structured data), and human readable reports in pdf format will be available to partners and operators. In addition, the Norwegian authorities (http://www.ptil.no ) require the daily drilling reports submitted via the web services or web browser interface they have provided since February 2008. Figure 1 below gives an overview of thegeneration, validation and use of daily drilling reports.

2.2 TerminologyAppendix 1 of this document lists a tabular version of the terminology used in the Daily Drilling Report. The concepts and definitions in the terminology have been developed according to the principles of ISO15926 standard (see section 3). For a complete overview, the reader will have to access PCA’s RDS which is the application where the reference data

1

http://www.ptil.no/

are stored and maintained. The application contains a “User guide”. The content (including the Daily Drilling Report terminology) of the RDS is called the Reference Data Library (RDL). The Intellectual Property Rights or the RDL belongs to PCA. The standard ISO15926 forms the basis of the RDL, and the ambition i to standardize relevant parts of the library through ISO.

2.2.1 How to read the terminologyThe types of data that are used when describing ‘things’ can be classified as either data about ‘objects’ or ‘properties’ related to objects.

Each type of object and property is documented in this document using a concept and a definition. To explain how the concepts and definitions should be read by the user, the terminology for a wellhead and christmas tree (valve tree) is used as an example.

Figure 2 illustrates a Product Model (PM) for a wellhead with Christmas tree. Examples of terminology related to the Christmas tree are shown in table 1 and table 2.

Figure 2: Drawing of a wellhead with Christmas tree. Names of some objects, or parts thereof, are shown in boxes. Properties are in italic.

All objects are arranged in super-subtype hierarchies where the more specialized object is a subtype of a more generic object. This can bee seen from the example table, Table 1, which follows.

From Table 1 it should be clear that a “Subsea horizontal Christmas tree” is a subtype of a “HORIZONTAL CHRISTMAS TREE” which again is a subtype of a “CHRISTMAS TREE”.

Table 1: A typical record documenting christmas tree types:CONCEPT DEFINITION

CHRISTMAS TREE

An artefact that is an assembly of pipes and piping parts, with valves and associated control equipment that is connected to the top of a wellhead and is intended for control of fluid from a well.

2

CONCEPT DEFINITIONHORIZONTAL CHRISTMAS TREE A Christmas tree configured with the master valves and flow-

control equipment on a horizontal axis to minimize the assembly height.

SUBSEA HORIZONTAL CHRISTMAS TREE

A horizontal Christmas tree design for subsea applications. The valves can be both bolted on or built in.

SURFACE HORIZONTAL CHRISTMAS TREE

A horizontal Christmas tree design for surface (dry land) applications. The valves are normally bolted on.

VERTICAL CHRISTMAS TREE A Christmas tree configured with the master valves and flow-control equipment on a vertical axis that is the main axis of the tree.

SUBSEA VERTICAL CHRISTMAS TREE

A vertical Christmas tree design for subsea applications. The valves are normally built-in as part of the tree.

SUBSEA CHRISTMAS TREE A christmas tree for use in a subsea environment. Will normally comprise a hollow, pressure rated body with the valves either built in or bolted on.

CHRISTMAS TREE 10K A Christmas tree rated for a pressure of 10 000 PSI (69,0 MPa)CHRISTMAS TREE 15K A Christmas tree rated for a pressure of 15 000 PSI (103,5 MPa)CHRISTMAS TREE 5K A Christmas tree rated for a pressure of 5 000 PSI (34,5 MPa)SURFACE CHRISTMAS TREE A Christmas tree for use on land. Will normally comprise a

number of assembled parts, e.g. casing spools, with the valves bolted onto the outside.

The two dimensional structure in the tables of this document is only suitable to show the specialization hierarchy, as shown in the example in Table 1. In the RDL other relations between objects are recorded. As shown in the example in Table 2, a “HORIZONTAL CHRISTMAS TREE” will normally have parts called a “CHRISTMAS TREE CAP”, “WELL PRODUCTION TUBING ASSEMBLY”, “WELL CASING ASSEMBLY”, “CASING HANGER” and “CHRISTMAS TREE VALVES” which again might be “ANNULUS VENT VALVE”, “ANNULUS MASTER VALVE”, “ANNULUS WING VALVE”, “ANNULUS CIRCULATION VALVE”, “CROSS OVER VALVE”, “CHEMICAL INJECTION VALVE”, “PRODUCTION MASTER VALVE” or “PRODUCTION WING VALVE”, and so on. These kinds of relations are not shown in the terminology tables, but they exist in the RDL. An example might be clarifying: If a user is looking for the concept “CASING HANGER” it will probably not be found under “HORIZONTAL CHRISTMAS TREE” in the terminology of this document. Instead it will be found under the less specialized concept STRING HANGER”, which is the “super class” of “CASING HANGER”. In the RDL, however, the user will be able to look up “HORIZONTAL CHRISTMAS TREE” and see that “CASING HANGER” is typically a part of it.

Table 2:.Typical associations and properties made to a horizontal christmas tree:CONCEPT DEFINITION

HORIZONTAL CHRISTMAS TREE A Christmas tree configured with the master valves and flow-control equipment on a horizontal axis to minimize the assembly height.

CHRISTMAS TREE CAP An artefact used to cap the top of the christmas tree, to prevent ingress of contaminants, such as seawater.

WELL PRODUCTION TUBING ASSEMBLY

An artefact designed to control production of the well. It normally consists of a string of tubing pipes reaching down to (one or more) productive zones in a well.

WELL CASING ASSEMBLY An artefact which is the assembly of casing pies, casing hanger and seals that is lowered into a well, and provides structural

3

CONCEPT DEFINITIONsupport for the borehole.

CASING HANGER A string hanger designed to suspend a well casing string down the well. The casing hanger is either screwed onto the top of each casing string or is held by slips. Acts as a wedge in a corresponding space inside the casing head, casing spool or wellhead

CHRISTMAS TREE VALVE A valve which is located on a christmas tree, for injection or fluid control.

ANNULUS VENT VALVE A valve which is located in the annulus outlet of the christmas tree for venting overpressure from the well annulus.

PRODUCTION MASTER VALVE A valve which is located in the production outlet of the christmas tree being the main production barrier valve

PRODUCTION WING VALVE A valve which is located in the production outlet of the christmas tree being the secondary production barrier valve

ANNULUS MASTER VALVE A valve which is located in the annulus outlet of the christmas tree being the main annulus barrier valve

ANNULUS WING VALVE A valve which is located in the annulus outlet of the christmas tree being the secondary annulus barrier valve

ANNULUS CIRCULATION VALVE

A valve which is located in the annulus outlet of the christmas tree for use when circulating in the well

CROSSOVER VALVE A valve which is located in the crossover loopCHEMICAL INJECTION VALVE A valve which is used to control injection of chemicals into the

well or flowlineTH CROWN PLUG A plug used in a tubing hanger to block the tubing hanger

bore. TUBING HANGER A string hanger designed to suspend a well tubing string down

the well. The tubing hanger uses slips or a bolted flange to hold the tubing string and fits as a wedge in the tubing head.

WELL CASING STRING An artefact that consists of pipes assembled end to end which is intended to line the walls of a drilled well.

WELL TUBING STRING An artefact that consists of lengths of pipe assembled end to end that extends from a producing zone to the wellhead, and used in a well to conduct fluids to the surface.

WELLHEAD HOUSING An artefact which is a thick-walled forged cylindrical pipe with one end attached to the surface (normally 20") casing string and the other end has couplings for connecting to a christmas tree.

2.3 DDR XML schemasThe current active version of the XML schemas for DDR is downloadable from EPIM’s homepage (http://www.epim.no).

The schemas are compliant to the current active version of the Wellsite Information Transfer Standard Markup Language (WITSML – http://www.witsml.org ). The custodian of WITSML is the organization Energistics (http://www.energistics.org). Energistics also assists in the maintenance and development of the XML schema for DDR.

The PCA RDL is used as a dictionary for the XML schemas. Elements in the schemas has been linked to corresponding RDL classes with annotations according to the W3C standard SAWSDL (http://www.w3.org/TR/sawsdl/ )

3 ISO 15926 general descriptionThe scope of ISO 15926 can be divided into two main categories:

4

http://www.w3.org/TR/sawsdl/

http://www.energistics.org/

http://www.witsml.org/

http://www.epim.no/

1. Support exchange of data between computer systems without loss of, or confusion in the semantic meaning of data.

2. To provide a platform for integration of life cycle data across multiple applications and across disciplines.

Data integration is combining information derived from several independent sources into one coherent data set. Because independent sources often have overlapping scopes, combining the data requires overlaps to be recognized, duplications to be removed, and possibly new data to be represented. To succeed in the role of integration, a data model must have a context that includes all the possible data wanted or required.

To support this, ISO 15926 defines a generic and conceptual data model that is independent of any particular industry and application, and a RDL that extends the data model to include the specific needs of any industry or application. The conceptual model defines the rules for describing ‘things’ and basic semantics, while the reference data extends the semantics into specific industries or business areas by establishing a set of terminology that is used to describe object types in specific industries. Where industries are using same types of objects, e.g. pipes, cables, steel profiles etc., reference data can be reused across industries. Whenever a concept is used across industries/disciplines with different meanings the process of establishing the RD ensures unambiguous terminology. This is required both for unambiguous exchange of data and for integration of data for an actual project. A consequence of this approach is that data is defined independent of applications. This approach therefore also supports the introduction of new work processes and business process reengineering.

The generic and conceptual design of ISO 15926 allows extensions to cover new areas by only adding new reference data.
