Upscaling gas permeability in tight-gas sandstones [PDF]
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

Prediction of natural gas prices depending of its reserves [PDF]
Natural gas as well as oil is the key energy resources in the world. This fuel is one of the exhaustible and non-renewable energy sources. The fact is that someday it will come to its exhaustion.

Reservoir and development characteristics of the Da'anzhai tight oil in Sichuan Basin, SW China
The oil in the Jurassic Da'anzhai reservoirs in the Sichuan Basin is unconventional tight oil, which accumulated in or near source rocks, and did not experience extensive migration in a large-scale long distance. The first submember, second submember and

Morphological and petrophysical evaluation of tight gas resources and energy production in Pakistan
Tight gas is a highly potential source of energy that can meet the energy deficit in Pakistan. The production of gas from conventional gas reserves are continuously declining in a massive manner and increasing demand of hydrocarbons as an energy source ...

Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
