Microstructural imaging and characterization of oil shale before and after pyrolysis

Fig. 13. (A) Porosity of 10 oil shale samples after pyrolysis at 500 °C, (B) – (D). 2-D gray scale images for organic-rich, organic-mixed and organic-lean regions respectively. (E) – (G) 3-D rendered volumes with the pore space visualized in blue.

Abstract The microstructural evaluation of oil shale is challenging which demands the use of several complementary methods. In particular, an improved insight into the pore network structure and connectivity before, during, and after oil shale pyrolysis is critical to understanding hydrocarbon flow behavior and enhancing recovery. In this experimental study, bulk

is required to know the values of porosity, water saturation, permeability, reservoir volume and the volumetric factor of the gas or oil; the Total Organic Carbon (TOC), thermal maturity, depositional environment, mineralogical composition and mechanical properties.

How to evaluate a shale play? Part A Emanuel Martin Introduction Shale formations constitute 60% of the rocks that make up the Earth's crust being only a small group of them containers of hydrocarbons. The necessary conditions to ensure that these rocks have generated and stored oil or gas is that they have abundant


Pores in shale plays

WHERE IS THE GAS STORED? Author:  Emanuel Martin Gas in an unconventional field is found in shale which is a rock  rich in organic matter belonging to the family of the mudrocks with the distinctive feature of breaking easily in thin layers. It´s constituted by particles of fine grains that have one
