# GeoSplit

> 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.

- **Founded:** 2013
- **Headquarters:** Dubai, United Arab Emirates
- **Founders:** Alexander Katashov (CEO)
- **Team size:** ~25 employees
- **Products:** GEOSPLIT quantum-dot marker-reporters, Marker-based production logging service, GeoExpert digital platform, Water cut and gas breakthrough diagnostics
- **Notable:** Developed quantum-dot marker-reporter technology for phase-resolved inflow monitoring in horizontal wells, Technology certified by Russia's State Commission on Mineral Reserves (GKZ), Raised $6.5M across seed and Series B rounds from Rusnano, Sistema and UCP Investment Group

## Products & services

- **GEOSPLIT quantum-dot marker-reporters** — Microsphere markers containing quantum dots that fluoresce in unique coded colors. Deployed during well completion, they tag specific zones and identify oil, water and gas inflow phase-by-phase from wellbore fluid samples.
- **Marker-based production logging service** — A wireline-free production logging and inflow-profiling service for horizontal and multistage-fractured wells, delivering years of production data without well intervention.
- **GeoExpert digital platform** — A decision-support platform that applies machine learning to marker survey data for dynamic production-profile surveillance and field-development optimization.
- **Water cut and gas breakthrough diagnostics** — Diagnostics that flag water breakthrough, gas breakthrough and packer/well-integrity issues in extended-reach and horizontal wells.

## Achievements

- Developed quantum-dot marker-reporter technology for phase-resolved inflow monitoring in horizontal wells
- Technology certified by Russia's State Commission on Mineral Reserves (GKZ)
- Raised $6.5M across seed and Series B rounds from Rusnano, Sistema and UCP Investment Group
