[back to projects] Description History Results Industry Value Futures Project Communications
The purpose of the project is to specify an XML-based markup language for reusable and sharable definitions of graphic presentations of well log data.
The following documents were developed by the participants in the project:
LogGraphicsML v1.0 25-Jun-2001 XML Schema specification Schlumberger proposal v0.4 20-Sep-2000 Revised after Sept 20 2000 meeting of work group Schlumberger proposal v0.3 14-Sep-2000 Revised after collaboration with SDC Changes Proposed by SDC 16-Aug-2000 Draft comparison of proposals by Schlumberger and SDC First Proposal DTD 30-Oct-1999 Annotated DTD based on First Proposal First Proposal v0.1 30-Oct-1999 Submitted by Kanai Patak, Schlumberger

The value of LogGraphicsML to the E&P industry is accrued in its use, as described in the following use cases:
- Well Log Rendering Input
- Reusable LogGraphicsML documents are easily produced or modified by users of well log graphics rendering systems, and can be used as control input by systems which implement the LogGraphicsML specification.
- " Schlumberger uses the LogGraphicsML standard for log formats in the Interact Web Witness product for displaying logs in a web browser. Schlumberger also has plans to use the LogGraphicsML standard for log format descriptions in future acquisition systems for Wireline and Drilling. "
- -- Kanai Pathak, Schlumberger
- " INT is implementing the LogGraphicsML specification so that it is supported by both our C++ and Java toolkits. We are also adopting it to use into our web-enabled Java welllog viewer, where we will use it for the specification of templates files. "
- -- Olivier Lhemann, INT
- Standard Presentation Registries
- Well log presentation catalogs may provide on-line or other access to shareable presentation definitions. Producers and consumers of rendered well log data, and well log data rendering systems, can communicate presentation requirements by catalog reference, without the need to replicate presentation documents.
- " POSC solicits comments, proposals, requirements, etc., for a project to implement and populate a repository of standard or common well log presentations. "
- -- Jim Theriot, POSC
The following have been suggested as topics for future work efforts:
Name Details Application Translators Identify and describe use cases and specify requirements for translators between LogGraphicsML and proprietary formats i. e. presentation definition input formats for well log graphic rendering systems. Presentation Registries Identify and describe use cases and specify requirements for registries of common or shared presentations.
