Unearth Insights with Field Geo Services

For more than 17 years, FGS has provided top-quality wellsite geology across most North American basins, offering mudlogging, advanced geochemistry, geosteering, and data analysis. Our innovative geoscience solutions like LithoAI and Spectrastacker are also simplifying daily wellsite geology operations and access to real-time information


A commitment to quality is our hallmark. Starting with highly qualified, experienced teams of degreed geologists, FGS adds extensive training in lag calculations, sample collection, and analytical methodology before deployment to the wellsite, empowering them to provide you with invaluable information about your well and the subsurface characteristics of your reservoir.

Define your Drilling

We designed our mudlogs with scientific accuracy and clarity in mind. Each interval includes a high-resolution photo of the associated cuttings to make interpretation as objective as possible—even in shale plays with only subtle changes in characteristics. We check every well log daily for errors, to ensure that your logs and data are accurate and ready for integration into your systems.

Quality and Support

Our teams talk—to each other, the drilling crew, the engineers, the scientists—and you. In an industry in which millions ride on good communication, FGS loggers keep you informed with the frequency, method, and specifics you prefer. Our teams produce consistent, high-quality data reports, delivered daily. We also offer 24/7/365 on-call support for both our wellsite geos and clients.
