Osman Varol has over 45 years of global expertise in calcareous nannofossil research and its industrial applications, with a focus on sedimentary sequences ranging from the Jurassic to the Tertiary.

Varol Research was established in 1991 by Osman Varol, following his resignation from Robertson Research, to support both scientific and industrial demands in calcareous nannofossil analysis. Its applications include stratigraphic monitoring, total depth (TD) determination, biosteering in horizontal drilling, and casing point placement in high-pressure/high-temperature (HP/HT) wells.
