Combustion Characteristics of Tight Sandstone

Energy & Fuels, 2018
As a promising unconventional energy source, tight sandstone gas has attracted increasing attention. Because of the extremely low porosity/permeability of tight sandstone, large scale exploration and development are still challenging. Recently, high-temperature combustion or pyrolysis has been employed to increase sandstone porosity/permeability.

A review on pore structure characterization in tight sandstones

Earth-Science Reviews, 2018
Abstract Tight sandstone reservoirs typically contain a wide pore throat sizes ranging from the nano-scale to micro-scale, and have complex pore geometry and pore throat structure. Microscopic pore throat structures are the most important factors affecting the macroscopic reservoir quality and fluid flow in tight sandstones.

Models for Saturation of the Tight Gas Sandstone Reservoir

Petroleum Science and Technology, 2014
The conventional model of formation saturation is restricted in well logging interpretation of tight gas sandstone because it is difficult to eliminate the influences of abrupt change of mineral component content. This paper studied the Triassic Xujiahe formation located in northeast Sichuan Basin, which has large variation of carbonate content between

Pore-throat sizes in sandstones, tight sandstones, and shales

AAPG Bulletin, 2009
Abstract Pore-throat sizes in siliciclastic rocks form a continuum from the submillimeter to the nanometer scale. That continuum is documented in this article using previously published data on the pore and pore-throat sizes of conventional reservoir rocks, tight-gas sandstones, and shales. For measures of central tendency (mean, mode,

Pore-throat sizes in sandstones, tight sandstones, and shales: Discussion

AAPG Bulletin, 2011
Wayne K. Camp Nelson (2009) prepared a nice compilation describing the wide range of pore-throat sizes that span a continuum from conventional sandstone reservoirs to unconventional tight-gas siliciclastic reservoirs and shale seals. In this article, Nelson (2009) proposes a new and rather unique definition for unconventional reservoirs (including ...

Anisotropic Rock Physics Modeling for Tight Sandstone

Proceedings, 2015
One distinguishing feature of low-porosity and low-permeability sandstones is the departure of the behavior of their elastic properties from that of general porous and permeable sands. This paper put forward the method to integrate rock physics model in tight sandstones due to the properties of developed cracks and its effect on tight sand.

Microcrack Permeability in Tight Gas Sandstone

Society of Petroleum Engineers Journal, 1983
Abstract A model of stress-dependent permeability was developed on the basis of flow through cracks. The compliance of the cracks is controlled by elastic deformation of a Gaussian distribution of surface asperities, indented into the opposing crack face.
