Summary

Dr. Sahar Mohammadi is an Assistant Scientist and courtesy Assistant Professor at the Kansas Geological Survey. Dr. Mohammadi’s research program focuses on regional diagenesis and mineralization of Paleozoic carbonate rocks in the southern Midcontinent of North America.

Research

  • Hydrothermal system and the effect of hydrothermal fluids on the carbonate and siliciclastic rocks
  • Fault and fracture control on reservoir properties
  • Petroleum geology
  • Mississippian reservoirs
  • Fluid inclusions
  • Diagenesis of carbonate and siliciclastic strata
  • Radiometric (U-Pb) dating on carbonate cements and fracture-fills
