Shale gas, although unconventional, is a prospective clean energy source. Shale gas
production is a complex multi-scale process with its spatial size ranging from the nanoscale …

This paper presents a comprehensive review of the technical progress as well as updated
knowledge and understandings of IOR/EOR technologies for tight oil reservoirs. Critical and …

Shale reservoirs are extensively exploited using hydraulic fracturing, which forms multiple
cracks that connect with the existing natural fractures to create a continuous path for the gas …

Shale gas is an important unconventional natural gas resource existing in shale reservoir
with huge reserves. Due to the ultralow porosity and permeability, it requires the horizontal …

Multiple transport mechanisms coexist in nanopores of shale gas reservoirs with complex
pore size distribution and different gas-storage processes, including continuum flow, slip …

Unconventional formations such as the Eagle Ford, Niobrara and Bakken have made a
significant impact on the oil industry over the last decade, but primary recovery factors are …

Surface diffusion plays a key role in gas mass transfer due to the majority of adsorbed gas
with abundant nanopores of organic matter in shale gas reservoirs. Surface diffusion …

A model for real gas transport in nanopores of shale gas reservoirs (SGRs) was proposed
on the basis of the weighted superposition of slip flow and Knudsen diffusion, where the …

The accurate knowledge of gas transport mechanisms through shale matrix will significantly
advance the development of shale gas reservoirs. At present, the different cross-section …

Unconventional reservoirs are the focus of considerable attention as a primary energy
source. Numerical simulation is a core kernel of reservoir-engineering work flows for …
