GEOLOG International
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. Follow for weekly case studies, technical insights, and field stories from GEOLOG specialists worldwide.
