Visualizing Stratigraphy Across Sites: A Complete Guide to Subsurface Correlation and Interpretation
Introduction Stratigraphy—the study of layered earth materials—is fundamental to understanding subsurface conditions in geotechnical engineering, environmental consulting, hydrogeology, and resource exploration. While individual borehole logs provide detailed vertical information, they offer limited insight into how subsurface layers extend and vary across a site. To truly understand geological conditions, professionals must visualize stratigraphy across multiple locations.…

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 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…

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…
