3、 Extensible Markup Language (XML) is a language for encoding documents containing structured information. XML has very broad application, but is widely recognized as a rapidly emerging standard for moving data over the Internet. XML files are basically structured text files and can be viewed just as

4、 you would any other file containing textual information. It is much more than just simple text, however, because it is also easily understood by computer software. For more introductory information on XML see XML in 10 Points from the W3C.Below is an example of a portion of an XML document: -999.25

The use of the Internet to exchange electronic business documents (eBusiness) is growing exponentially. Organizati

6、ons engaged in eBusiness are quickly converging on the use of XML as the best way to exchange information. The reason for this is that XML, a standard defined by the World Wide Web Consortium (W3C), is a simple, easy to grasp method of encoding information in plain text. In addition to being a very

7、sound means for moving data over the Internet, XML files provide a good way of moving data between applications.The power of the growing XML marketplace affords the oil and gas community the opportunity to leverage the XML organizations and software that are being created to tremendous advantage. By

8、 adopting this new technology, industry can lower the cost of maintaining and exchanging well log data and more easily exploit the Internet revolution to greatly improve the efficiency of doing business.What is POSC Doing with XML? POSC is promoting the creation of standard XML document definitions

9、(called Document Type Definitions, or DTDs for short) for use in exchanging E&P data in several domains. We currently have three active projects relating to XML: MMS data reporting; a reference data service; and a new exchange format for E&P information. View project details.What Are Some Other Sign

10、ificant XML-Related Initiatives? Several organizations (e.g., BizTalk and XML.org) have been established to promote the publication and use of common XML formats for data exchange in various business domains. The memberships of these groups include the foremost companies from a broad spectrum of ind

11、ustries, e.g., Microsoft, IBM, Sun Microsystems, The Boeing Company, J. D. Edwards & Company, SAP AG, Oracle, etc. (See the eBiz Links page, the Organizations Links page and the XML Links page for more information.)POSC XML Related ProjectsWellLogML 1.0 for Well Log Data Exchange This project, spons

12、ored by POSC, Oilware and INT, is focused on creating an XML DTD for exchanging well log data. Version 1.0 of that DTD has been published by POSC. The sponsors envision that the WellLogML specification will replace the popular LAS format as the preferred means of exchanging well log data in the Indu

A schema specification using the XML Schema standard has been published. Most of the comm

WellPlotML: A Proposed Standard for the Presentation of Well Log and Related Information Technology continues to transform the way we distribute well logs. Compared to the t

Ongoing initiatives such as XML provide the means to combine the delivery of well data and plot information into a single, seamless process. Last year saw the emergence of two XML st

The project is incorporating various XML technologies to accomplish its objectives.BLM Sample XML Files POSC

18、is also working with the BLM to help them investigate XML for electronic submission of regulatory data. This project shows how three common regulatory reports can be defined, captured and presented in XML.ProductionML/Reporting This is a project to develop an XML DTD for use in reporting well tests,

19、 monthly and annual production and performance forecasts to regulatory agencies. We have constructed a preliminary DTD for reporting on wells, reservoirs by well, fields, leases/licenses and facilities. Another goal of this project is to investigate the possibility to create and maintain a customize

The scope is the entire well, including the wellhead and multiple wellbores, boreholes, casing and tubing strings, surface and downhole equipment, perforations

21、 and open hole intervals, survey points and workover (intervention) intervals.Geophysics ML Proposals The description of geophysical acquisition and processing objects (e.g., source events, stations, receivers, bin nodes) and data sets which reference them is the subject of this proposed project.

The initial project will develop an initial working draft for a possible standard.XML-Based Reference Service P

23、OSC is proposing to develop a reference data service accessible over the Internet. The proposed service relies on XML technology as the basis for storing the reference values.POSC Exchange Format (PEF) in XML The RP66 formulation of POSC Exchange Files has been too heavy for general use.
