Masa Prodanovic Research Projects

Digital Rocks

The Digital Rocks Portal was released in 2015.

Our mission is to:

  • Organize and preserve images and related experimental measurements of different porous materials,
  • Improve access to them for a wider community of geosciences and engineering researchers not necessarily trained in computer science or data analysis, and thus
  • Enhance productivity and enable scientific inquiry and engineering decisions founded on a data-driven basis.

 

Fundamentals of Gas Transport in Tight Gas Sandstones and Shales

Principal Investigator: Steven L. Bryant (in collaboration with Masa Prodanovic, Peter Eichhubl (BEG) and Peter Flemings (BEG))

Mechanisms of Porosity Reduction

Several unique characteristics of these rocks are the consequence of post depositional diagenetic processes including mechanical compaction, quartz and other mineral cementation, and mineral dissolution. These processes lead to permanent alteration of the initial pore structure causing an increase in the number of isolated and disconnected pores and thus in the tortuosity.

Gas EOR Project 9: Effect of Core Heterogeneity and Injectant Composition on Sorm

Primary Investiagors: Kishore Mohanty, Masa Prodanovic

The goal of this project is to correlate residual oil saturation to miscible flood with core-scale heterogeneity. Cores of different lithology will be used. Cores will be characterized by microscopy and mercury porosimetry. Multi-contact miscible floods will be conducted and the residual oil saturation to miscible flood will be measured. Effect of impurities will be assessed.

Numerical Simulation of Diagenetic Alteration and its Effect on Residual Gas in Tight Gas Sandstones

Masa Prodanovic and Steven Bryant

 The geometry of intergranular pore space in tight gas sandstones (at the porosities less than 10%) differs from conventional reservoir sandstones in some fundamental aspects: the fluid pathways are significantly narrower so that pore body/pore throat aspect ratios are larger, and some percentage of the fluid pathways are closed and disconnect the pore space.
