Dr. Jalel Jaballah

Post-Doc Researcher, Geosciences Department

Dr. Jalel Jaballah is a Post-Doc Researcher in the Carbonate Sedimentology Group with Saudi Aramco Chair Prof. John Reijmer. He holds a Ph.D. degree in Geology from Tunis el Manar University, Tunisia in the field of sedimentology, sequence stratigraphy and diagenesis of the Cretaceous carbonate series of Tunisia. He combined his Ph.D. studies with working on projects for the industry involving reservoir aspect characterization.

Educational Qualification

  • Ph.D. in Geology (Carbonate Sedimentology), Tunis el Manar University, Faculté des Sciences de Tunis, Tunisia, 2012-2017.
  • M.S. (Applied Geology), Carthage University, Faculté des Sciences de Bizerte, Tunisia, 2009-2011.
  • B.S. (Earth Sciences), Carthage University, Faculté des Sciences de Bizerte, Tunisia, 2004-2008

Research Interests

Dr. Jaballah focuses on carbonate sedimentology within a variety of tectonic basin settings and climatic regimes. This involves the joint application of outcrop and subsurface sedimentological data to improve model development and reservoir characterization.

His project at CPG aims to identify and delineate variations in lithology and porosity in different facies of the Cretaceous of Albania and Saudi Arabia. A range of techniques will be employed to image and locate features at different scales from core (cm) to pore (μm). Analytical methods include transmitted light microscopy, micro-CT scanning, Scanning Electron Microscopy (SEM), Mercury Injection Capillary Pressure (MICP) and AutoScan analysis (scanning core plugs for gas permeability, resistivity, ultrasonic compressional and shear-wave velocities, and composition). These techniques allow the identification and quantification of lithological variations, porosity, pore morphology and pore network structure. A key challenge is to inter-relate multi-scale data obtained through the application of different techniques.
