Predicting Surface Diffusivities of Gas Molecules in Shale

Shale Gas Productivity Predicting Model and Analysis of Influence Factors

Abstract: In order to find the dynamic characteristics of shale gas reservoirs and improve shale gas well production, it is very important to research on shale gas seepage mechanism and production evaluation. Based on the shale gas seepage mechanism, adsorption and desorption characteristics, the diffusion mechanism and mass conservation theory in shale gas development, the dual pore medium sha...

Shale gas development impacts on surface water quality in Pennsylvania.

Concern has been raised in the scientific literature about the environmental implications of extracting natural gas from deep shale formations, and published studies suggest that shale gas development may affect local groundwater quality. The potential for surface water quality degradation has been discussed in prior work, although no empirical analysis of this issue has been published. The pot...

Shale gas and hydrofracturing.

About the Cover: Black carbon (BC) containing particles have an important role to play in climate change; directly heating through absorption of radiation, and/or indirectly cooling through the seeding of clouds. New research in this issue, using a mobile laboratory indicates that gasoline powered cars may produce more BC than previously considered. Transmission electron microscopy background i...

Gas Flow Behavior of Nanoscale Pores in Shale Gas Reservoirs

The gas transport in shale nanopores is always one of the major concerns in terms of the development of shale gas reservoirs. In this study, the gas flow regimes in shale nanopores were classified and analyzed according to Knudsen number. Then the gas flow model considering Darcy flow, slip flow, transition flow, molecular free flow and adsorption effect was proposed to evaluate the gas flow be...
