From data-storage software to oilfield tracers, Alexander Katashov has built a career around making hidden processes useful. His route runs through Panasonic, patient field trials and the work of turning a laboratory result into something a customer will buy.
GeoSplit is a high-tech oilfield services company that monitors oil, gas and water flows inside horizontal wells using quantum-dot marker-reporters and machine-learning interpretation. Instead of running mechanical logging tools downhole, operators deploy tiny fluorescent markers during well completion and later collect fluid samples that reveal, phase by phase, how each section of a well is producing - delivering years of production data without well intervention. Founded in 2013 and now headquartered in Dubai, the company serves upstream oil and gas operators seeking lower-cost, longer-term well diagnostics.
