Characteristics of rock types and exploration significance of the shale strata in the Chang 73 sub-member of Yanchang Formation, Ordos Basin, China

Journal of Natural Gas Geoscience, 2021
For a long time, the Chang 73 sub-member of the Ordos Basin was mostly investigated as a single source rock, with hardly any investigation into the characteristics of various rock types or the integration of source and reservoir.

The permeability of ablative materials under rarefied gas conditions [PDF]

, 2015
Numerical meshes of both cork and carbon fibre ablative materials in their virgin and pyrolised states, with realistic porosity and tortuosity, have been created from micro-computed tomography (μCT) scans.

Research on Refracturing Technology of Horizontal Wells Based on Dynamic Drainage Volume

Frontiers in Energy Research, 2022
Refracturing is an important method to improve the productivity of low-yield and low-efficiency horizontal wells. Due to the influence of geological factors and primary fracturing, it is of great importance to select suitable candidate wells and ...

Effect of sedimentary heterogeneities in the sealing formation on predictive analysis of geological CO₂ storage [PDF]

, 2019
Numerical models of geologic carbon sequestration (GCS) in saline aquifers use multiphase fluid flow-characteristic curves (relative permeability and capillary pressure) to represent the interactions of the non-wetting CO2 and the wetting brine. Relative

Gas Permeability of Polymers [PDF]

Journal of Chemical Education, 2005
The recent article, “Applying Chemical Potential and Partial Pressure Concepts To Understand the Spontaneous Mixing of Helium and Air in a Helium-Inflated Balloon”, proposes a model of permeation untenable and in contradiction with correct statements present in the same text and consequently does not consider the material of which the investigated ...
