Binary pore structure and fractal characteristics of tight sandstone: A case study of Chang 7 Member of Triassic Yanchang Formation in Ordos Basin

open access: yesYouqi dizhi yu caishoulu
The pore structure characteristics of tight sandstone are of significance for the exploration and development of tight oil reservoirs. However, little attention is paid to the flow characteristics and influencing factors of different types of pores. This

Squirt flow in a tight sandstone: an interlaboratory study

open access: yesGeophysical Journal International
SUMMARY In the spirit of interlaboratory benchmarking of related techniques, we have re-examined the seismic-frequency mechanical properties of a low-porosity Wilkeson sandstone specimen tested in axial stress oscillation under water-saturated conditions by Pimienta et al.

Upscaling gas permeability in tight-gas sandstones [PDF]

open access: yes, 2018
Klinkenberg-corrected gas permeability (k) estimation in tight-gas sandstones is essential for gas exploration and production in low-permeability porous rocks. Most models for estimating k are a function of porosity (ϕ), tortuosity (τ), pore shape factor (s) and a characteristic length scale (lc). Estimation of the latter, however, has been the subject

Logging evaluation method of fracturability of tight sandstone reservoirs

open access: yes
The fracturability of reservoirs is an essential parameter for selecting perforation stages and predicting hydraulic fracturing effects, but fracturability evaluation for tight sandstone reservoirs lacks unified methods and standards.
