Because XML files contain clear text formatted data, they are
human-readable and understandable. WellLogML provides support for array
curves and for array parameters. It also supports numeric and text based
channels, run data and both evenly and unevenly spaced indexes.
With WellLogML, or any XML file for that matter, there is less need for a
specific "certify" program. There are many tools available (free) that are
capable of certifying XML files for structural integrity. Currently,
Internet Explorer V5.0 has built in functionality to certify the structure
of a WellLogML file. There are some rules for constructing a valid WellLogML
document that cannot be encoded in a Document Type Definition, however, so
special software will be required to fully verify a WellLogML document.
Because XML files separate data content from data display, there are also
tools available to support the presentation of the XML data. This
characteristic seems tailor made for well log data where petrophysicists can
set up their preferred presentation formats for displaying the same data.
The WellLogML DTD and Schema specifications are available at WellLogML
1.0 Specification Details
LogGraphicsML 1.0: XML Format Description Standards for Well Log Graphics
The objective of this project is to specify an XML-based markup language
for definitions of graphic presentations of Well Log data. A schema
specification using the XML Schema standard has been published. Most of the
common well log graphic objects are supported in this initial release,
including track, index, channel, trace, pip, and fill area.
WellPlotML: A Proposed Standard for the Presentation of Well Log and Related
Information
WellPlotML aims to establish the way users can collaborate over the Web
(Internet and/or Intranet) using these and other evolving standards.
MMS Reporting Proposal
POSC is working with the MMS to help them establish the means for
electronic submission of regulatory information.The project is incorporating
various XML technologies to accomplish its objectives.
BLM Sample XML Files
POSC 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,
monthly and annual production and performance forecasts to regulatory
agencies. A preliminary DTD has been constructed 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
customized DTD as the source specification evolves.
WellSchematicML
The description of well schematics in XML is the subject of this proposed
project. The scope is the entire well, including the wellhead and multiple
wellbores, boreholes, casing and tubing strings, surface and downhole
equipment, perforations 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. Both seismic and potential
field data are included.
eosML Proposal
This is a project to rapidly develop an XML specification for equation of
state (EOS) data for compositional fluid modeling. The initial project will
develop an initial working draft for a possible standard.
XML - Based Reference Service
POSC 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. The PEF XML proposal maps Epicentre (or any data model, for
that matter) into an XML file in a simple, consistent manner. The July 20,
2001 paper is a formal recommendation for this XML file.
XML Components and Objects
Use of XML Schema to develop various XML files has led to the development
of "XML Objects." These are complex data types, structures, and patterns
that can be incorporated into larger XML Schemas. The advantage in these
objects is that they will be consistent over many different XML
applications.
