Creating Fence Diagrams in WinFence: A Complete Guide to Subsurface Visualization
Introduction Understanding subsurface conditions is one of the most critical aspects of geotechnical engineering, environmental site assessment, and hydrogeological analysis. While borehole logs provide detailed vertical information, they are inherently limited in their ability to communicate spatial relationships across a site. This is where fence diagrams become essential. Fence diagrams connect multiple boreholes along defined…

Using Templates for Faster Borehole Logging: Standardizing Geotechnical Workflows in WinLoG
Introduction Borehole logging is a fundamental task in geotechnical engineering, environmental consulting, and hydrogeology. It transforms raw field data into structured, interpretable records that support analysis, modeling, and reporting. However, traditional borehole logging workflows can be slow, repetitive, and prone to inconsistencies—especially when logs are created manually or without standardized formats. This is where templates…

Editing and Structuring Lithology Data: Best Practices for Accurate Borehole Logs and Geoscience Workflows
Introduction Lithology data is one of the most critical components of any borehole log. It provides a detailed description of subsurface materials, forming the basis for geotechnical analysis, environmental assessments, hydrogeological modeling, and engineering design. However, lithology data is often inconsistent, unstructured, and difficult to interpret—especially when collected across multiple projects, teams, or field personnel.…

Creating a Borehole Log from Field Data Using WinLoG and WinLoG Field Assistant
Introduction Borehole logs are the backbone of geotechnical, environmental, and hydrogeological investigations. They transform raw field observations into structured, interpretable datasets that support engineering design, groundwater analysis, and regulatory reporting. However, the process of converting field notes into professional borehole logs can be time-consuming and error-prone—especially when relying on manual transcription or inconsistent data entry…

Scanning and Structuring Historical Borehole Logs for Digital Analysis
Introduction Borehole logs are among the most valuable records in geoscience, capturing detailed information about subsurface conditions encountered during drilling. These logs—ranging from lithological descriptions and drilling records to geophysical measurements—provide critical insights for applications such as groundwater studies, environmental assessments, mining exploration, and infrastructure development. For decades, borehole logs were recorded on paper, often…

Transforming Legacy Geological Archives into Structured Digital Databases
Introduction Across the geoscience industry, vast volumes of geological data remain locked in legacy archives. These archives—often consisting of paper records, scanned images, field notebooks, maps, seismic sections, and well logs—represent decades of exploration, research, and operational investment. Yet much of this data is underutilized because it exists in formats that are not easily searchable,…

Digitizing Geological Maps for GIS and Subsurface Modeling
Introduction Geological maps are foundational tools in geoscience, providing critical insights into lithology, structural features, stratigraphy, and surface expressions of subsurface conditions. For decades, these maps were created as paper documents—carefully drafted, annotated, and archived by geologists in government surveys, oil and gas companies, mining firms, and environmental consultancies. Today, vast collections of these maps…

Image Processing Techniques for Seismic Section Digitization
Introduction Seismic sections are among the most information-rich datasets in geoscience, capturing subsurface structures through reflections of seismic energy. For decades, these records were stored as analog outputs—paper sections, film reels, and microfiche—produced by early seismic acquisition systems. Today, vast archives of these vintage seismic sections remain underutilized, largely because they exist outside modern digital…

Converting Analog Seismic Profiles into Digital Seismic Data
Introduction Seismic data has long been a cornerstone of subsurface exploration, enabling geoscientists to visualize geological structures, identify hydrocarbon reservoirs, map aquifers, and support environmental investigations. For decades, seismic surveys were recorded and stored in analog formats such as paper seismic sections, film reels, and microfiche. While these legacy datasets contain immense geological value, their…

Digitizing Vintage Seismic Sections for Modern Subsurface Interpretation
Introduction For more than half a century, seismic reflection surveys have been one of the most powerful tools for understanding the Earth’s subsurface. From early oil and gas exploration to modern environmental investigations and critical mineral exploration, seismic sections have helped geoscientists visualize geological structures buried thousands of meters below the surface. However, a vast…
