Abstract: The increasing adoption of systems such as Measurement While Drilling (MWD) has created a critical need for standardized data management and interchange formats in the geotechnical industry. While MWD systems generate valuable subsurface information, the data often remains siloed in proprietary formats, limiting its broader utility and long-term preservation. This paper will present the implementation of the Data Interchange for Geotechnical and Geoenvironmental Specialists (DIGGS) format for MWD data, demonstrating a solution for standardized data exchange and storage.
We detail the development and implementation of conversion tools for two widely used MWD data formats: Hatlapa (.guh) and LIM (.bor). These tools enable seamless transformation of proprietary data into the open-source DIGGS format, facilitating data sharing and long-term accessibility. A key component of this work was the creation of a comprehensive MWD code list dictionary, which standardizes the documentation of MWD-specific variables, including drilling parameters, sensor measurements, and operational indicators.
To ensure data integrity and compliance, we implemented a multi-level validation framework. This includes XML structure validation, code list usage verification, and Schematron rules that enforce both structural and semantic constraints. These validation tools provide users with immediate feedback on data quality and conformance to the DIGGS standard, promoting confidence in data exchange and reuse.
The paper will address the broader implications of standardized data formats for the geotechnical community, including improved data preservation, enhanced collaboration opportunities, and the potential for large-scale data analytics. We discuss practical considerations for implementation and provide recommendations for industry-wide adoption of DIGGS for MWD applications.
This work represents a significant step toward establishing a robust, open-source ecosystem for geotechnical data management, particularly in the growing field of MWD applications
