Every day, people around the world live, work and play on ground prepared by Keller, the world's largest geotechnical specialist contractor.
Used alone or in combination, our techniques solve a wide range of challenges across the entire construction sector – from industrial, commercial and housing projects to infrastructure construction for dams, tunnels, transportation and water treatment, as well as projects to address environmental challenges.
Global strength and local focus are what makes us unique. Our knowledge of local markets and ground conditions means we’re ideally placed to understand and respond to a particular local engineering challenge. Our global knowledge base then allows us to tap into a wealth of experience, and the brightest minds in the industry, to find the optimum solution.
With around 10,000 employees and operations across five continents, we have the people, expertise, experience and financial stability to respond quickly, get the job done and see it through safely.
By connecting global resources and local knowledge, we can tackle some of the largest and most demanding projects around the world but the everyday work we do is just as important and, in total, we tackle an unrivalled 6,000 projects every year.
Be it testing, inspections, certifications or supply chain solutions, the experienced engineers and specialized technicians of NTS stand ready to make your project a success. For more than 50 years, our commercial and military partners have trusted our diverse engineering capabilities to ensure their products are developed and perfected in compliance, on time and on budget. Discover how our global resources and the largest national network of fully accredited laboratories in North America can help you deliver stronger, safer, more reliable products to market quickly and efficiently.
Every year, drilling teams make decisions worth millions of dollars on incomplete information.
A bit drilled past its life. A borehole left uncleaned before a critical section. A gas show missed because the detection system wasn't precise enough.
GEOLOG exists to close that gap.
We are an independent specialist in surface logging, drilling intelligence, and formation evaluation – operating in more than 40 countries across Europe, the Middle East, Africa, and the Americas. Independent means we have no equity interest in any well outcome. Our role is to measure and advise – without agenda.
That independence is why major NOC and IOC operators rely on our specialists on their most complex wells.
Specialist means we do surface logging and drilling intelligence at the highest level of accuracy the industry can deploy at the surface. Our technologies – DrillClean, BitLife, KickMaster, G9+, GeoIsotopes, Digital Cuttings, Vinci Geomechanics – are patented, peer-reviewed, and field-proven on hundreds of wells globally.
Measured means every claim we make is backed by data. DrillClean has saved a single operator $150,000 on one well and $1.075 million across five wells in Kuwait. BitLife has prevented $15 million in drilling costs on a single deep-water program.
We are also active beyond oil and gas – applying our subsurface measurement science to geothermal energy, CCUS, and critical minerals.
