Formation Parameters Of The Lower Eocene Rocks In Qatar

Abstract

The study of some carbonate rock samples collected from four different locations in Qatar and attributed to the Rus Formation (Lower Eocene) reveals that these rocks are mainly heterogeneous in their petrophysical characteristics. This was indicated not only by study of pore space geometry but also by a skewed distribution of porosity, permeability, and hydraulic conductivity measured data. Parameters enhance reservoir evaluation and description were estimated. Whereas, useful empirical relations have been derived by which both the storage capacity and the gas—permeability of the studied rocks can be determined. Study of SEM-micrographs has shown the influence of post-depositional processes on both porosity and gas-permeability with different degrees of performance.
