The Evolution of Borehole Logging Software: From Paper Logs to AI-Powered Subsurface Intelligence
For more than a century, borehole logs have been one of the most important records produced during geological, geotechnical, hydrogeological, environmental, and mining investigations. They document the subsurface conditions encountered during drilling and provide the information engineers and geoscientists rely upon to design foundations, estimate mineral resources, assess environmental conditions, manage groundwater, and build critical…

Building a Trusted Subsurface Intelligence Platform: The Future of Geological, Geotechnical, and Environmental Data Management
The subsurface is one of the least visible yet most critical components of every engineering project. Before a bridge can be designed, a mine developed, a contaminated site remediated, or a groundwater supply evaluated, engineers must understand what lies beneath the surface. That understanding depends on data—millions of individual observations collected from boreholes, samples, laboratory…

Continuous Validation During Data Entry: Catching Borehole Data Errors Before They Become Engineering Problems
The quality of any geological, geotechnical, hydrogeological, or environmental investigation depends on the accuracy of the data collected in the field and entered into the project database. Every borehole interval, groundwater measurement, Standard Penetration Test (SPT), laboratory result, and geological observation contributes to engineering decisions that may affect public safety, project costs, regulatory compliance, and…

Intelligent Borehole Databases and Knowledge Graphs: The Next Evolution of Subsurface Data Management
For decades, borehole databases have served as digital filing cabinets for geological, geotechnical, hydrogeological, and environmental information. They store borehole logs, laboratory results, groundwater measurements, sampling records, geological descriptions, and engineering observations in structured tables that can be searched and reported. While this represented a major advancement over paper records, today’s engineering projects demand far…

The Future of AI-Assisted Geological Validation: How Artificial Intelligence Is Transforming Borehole Data Quality
Artificial intelligence is rapidly changing the way engineers and geoscientists work. From predictive maintenance and autonomous drilling to environmental assessments and digital twins, AI is helping organizations analyze larger datasets, automate repetitive tasks, and uncover patterns that would be difficult—or impossible—for humans to detect manually. One of the most promising applications is AI-assisted geological validation.…

Geotechnical QA/QC for Infrastructure Projects: Building Reliable Foundations Through High-Quality Subsurface Data
Every successful infrastructure project begins below the surface. Before a highway is widened, a bridge is constructed, a railway is extended, or a water treatment plant is built, engineers must understand the subsurface conditions that will support the structure for decades to come. This understanding comes from geotechnical investigations. Boreholes, Standard Penetration Tests (SPT), cone…

SPT and N-Value QA/QC Procedures: Improving the Accuracy and Reliability of Standard Penetration Test Data
The Standard Penetration Test (SPT) is one of the most widely performed in-situ geotechnical tests in the world. From building foundations and bridges to highways, dams, pipelines, and environmental investigations, SPT results are used daily by geotechnical engineers to evaluate subsurface conditions and support critical engineering decisions. At the heart of every SPT is the…

Geological Data Quality and Resource Estimation: Why High-Quality Borehole Data Is the Foundation of Reliable Resource Models
Whether evaluating a mineral deposit, planning a mine, designing a major infrastructure project, or assessing groundwater resources, every geological interpretation begins with data. Drillholes, samples, laboratory analyses, geological logging, geotechnical measurements, and geophysical surveys collectively form the foundation upon which three-dimensional geological models and resource estimates are built. The accuracy of these models depends directly…

Recovery, RQD, SCR, and TCR Validation: Ensuring Reliable Core Logging Data for Better Engineering Decisions
Core drilling provides some of the most valuable information used in geotechnical engineering, mining, hydrogeology, and environmental investigations. However, the value of that information depends entirely on the quality and consistency of the recorded data. Among the most important measurements collected during core logging are Core Recovery, Rock Quality Designation (RQD), Solid Core Recovery (SCR),…

Core Logging QA/QC in Mineral Exploration
Best Practices for Producing Accurate, Consistent, and Defensible Geological Core Data Diamond drilling is one of the largest investments made during a mineral exploration program. Every metre of core recovered represents significant drilling costs and provides valuable geological information that may influence exploration strategy, resource estimation, mine planning, and investment decisions. Because of this, the…
