Observation of nano-scale pore structure in a tight gas siltstone reservoir

Abstract

In this paper, petrophysical property measurements of Montney tight gas siltstones in Western Canada are discussed. We combined petrophysical measurements with advanced laboratory imaging apparatus such as micro focus X-ray CT imaging and high resolution scanning electron microscope (SEM) imaging. The laboratory imaging allowed us to interpret the measured petrophysical properties in terms of directly observed physical phenomena.
