THIN SECTION PETROGRAPHY
Example of a Thin Section Description Report
Ø = 6.8%. Ka = 4.55mD. MGS = 308 Microns
Thin Section Descriptions: Fine to medium-grained, moderately well sorted, relative clean, quartz-rich (70%) sandstone.
The porosity has a patchy distribution, with cluster of high porosity in one place and relatively low porosity in others.
The large pores (P) seen in image A and B are most probably secondary pores generated by the selective dissolution
of some unstable grains. The green arrow in image A points to an artificial microfracture created along a pre-existing stress line.
The red arrow in image C points to a channel-like elongated pore space. Thin section photomicrograph D & F shows colorful,
high birefringence anhydrite minerals that locally fill the pore spaces, contributing to the patchy distribution of porosity.
