Nanometer-Scale Pore Characteristics of Lacustrine Shale, Songliao Basin, NE China

Nanometer-Scale Pore Characteristics of Lacustrine Shale, Songliao Basin, NE China

In shale, liquid hydrocarbons are accumulated mainly in nanometer-scale pores or fractures, so the pore types and PSDs (pore size distributions) play a major role in the shale oil occurrence (free or absorbed state), amount of oil, and flow features. The pore types and PSDs of marine shale have been well studied; however, research on lacustrine shale is rare, especially for shale in the oil gen...

Pore Characteristics of the Upper Carboniferous Taiyuan Shale in Liaohe Depression

High pressure mercury, nitrogen adsorption, nano-CT, and scanning electron microscope with energy spectrum analysis were conducted on core shale samples for studying the characteristics of Taiyuan formation in the eastern uplift of Liaohe depression. The research results show that the shale gas reservoir pores are mainly open pores such as the wedge-shape pores and parallel-plate pores. By a ge...
