MWD Data Exchange using the DIGGS Schema-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes efforts to make measurement-while-drilling (MWD) data easier to share and preserve using DIGGS, an open XML-based geotechnical data standard built on OGC’s Geography Markup Language. Although MWD adoption is growing, manufacturers use incompatible formats, creating data silos that hinder comparison, cross-project analysis, and long-term access.<br /><br />To address this, the team extended DIGGS to support MWD and developed a code-list dictionary with 36 standardized properties, covering drilling parameters, sensor measurements, and derived values. The dictionary is designed to evolve through community contributions. Open-source Python tools convert Hatlapa and LIM data into the standard format, accommodating missing values and inconsistent formatting.<br /><br />The presentation also outlines a three-stage validation process: checking XML structure, confirming code-list compliance, and applying Schematron rules to test semantic relationships. Free validation tools, including an AI-powered DIGGS assistant, are available through Geosetta.<br /><br />Standardized MWD data can improve data longevity, collaboration, cross-project analytics, and market access. Adoption can be encouraged by owners requiring DIGGS compatibility, software vendors supporting import and export, and equipment manufacturers offering native DIGGS output. The schema, code list, conversion tools, and validation resources are available through DIGGS and Geosetta.
