Molecular simulation of CO2/CH4 competitive adsorption in organic matter pores in shale under certain geological conditions

open access: yesPetroleum Exploration and Development, 2016
To reveal competitive absorption behavior between CH4 and CO2 in organic matter (OM) nanopores, OM pore structure was first characterized using focused ion beam−scanning electron microscope (FIB-SEM) and pore-size distribution was studied using N2 ...

Do oil price increases cause higher food prices? [PDF]

open access: yes, 2013
U.S. retail food price increases in recent years may seem large in nominal terms, but after adjusting for inflation have been quite modest even after the change in U.S. biofuel policies in 2006. In contrast, increases in the real prices of corn, soybeans,

Thermo-Hydro-Mechanical Coupling Numerical Simulation on Mechanical Heterogeneity of Coal Rock

open access: yesGeofluids, 2022
Coal rock is a porous medium composed of organic matter and inorganic minerals, and it is very complex and highly heterogeneous. Coal bed methane (CBM) production is a thermo-hydro-mechanical (THM) coupling process in heterogeneous coal rock.

US Tight Oils [PDF]

open access: yes, 2013
This paper examines the implications of the rapid growth in US tight oil production for US and global energy markets. The behaviour of US crude markets is analysed, with a particular focus on changing arbitrage dynamics. The rapid growth in US tight oils production was not met with an equally fast response by the US midstream companies, resulting in ...
