Rachel Angelo Sabuni

School of Mines and Geosciences

Petroleum Science and Engineering

Biography

Geoscientist specialising in the geochemical and stratigraphic analysis of sedimentary basins, with a focus on hydrocarbon exploration and resource evaluation. My research integrates petroleum geochemistry, basin analysis, and environmental assessment to better understand the origin, migration, and alteration of hydrocarbons within the Earth’s crust and at its surface.
In addition to my petroleum geochemistry background, I have also worked in graphite exploration in Ruangwa and gold exploration in Geita, gaining experience in mineral resource exploration. I am also open to consultancy opportunities in petroleum and mineral exploration, geochemical analysis, and environmental impact assessment.  I am bringing a research driven yet practical approach to solving geological and energy-related challenges.

Research Interest

 Petroleum geochemistry, basin analysis, Oil and Gas seeps including its environmental assessment to better understand the origin, migration, and alteration of hydrocarbons within the Earth’s crust and at its surface. Am also open to consultancy opportunities in petroleum and mineral exploration,
