Project Description
Shallow marine carbonate sediment can be significantly modified by microbial activity through encrustation, endolithic activity, or micritization on the seafloor. These alterations can be preserved in the carbonate rock records and can be used as paleo-environmental indicators and promote the development of microporosity. To assess the extent of microbial diagenesis, we buried consolidated sediment plugs in various lagoonal environments around the Arabian Peninsula (KSA, UAE, Oman) and recovered them after one year. This research project aims to compare the pre- and post-burial CT scan models of the plugs quantitatively to identify potential microbial alterations. SEM, BS-SEM, and thin section imaging are also envisaged. For this project, we are seeking for a motivated student or recent graduate with a strong background in geomodelling/geodata science and/or carbonate sedimentology.

Research Interests
a€‹Professor Vahrenkamp's research aims at securing future energy supply with three main thrusts: Refine the understanding of modern and ancient carbonate depositional environments and associated diagenesis for improved perception of reservoir heterogeneities on multiple scales, Advance the quantification of the complex pore networks of Arabian carbonate reservoirs and its impact on reservoir performance, Explore and develop geothermal energy in Arabian countries with special focus on desalination and cooling applications and suitable drilling techniques.Selected Publications
