Experimental study of the permeability of clays from the potential sites for acid effluent storage.
An evaluation of Re, as an alternative to Pt, for the 1 bar loop technique: An experimental study at 1400 °C
Evaluation of Re alternative to Pt 1 bar loop technique:An experimental study 1400 °C
2012/4/1
Previous investigators have shown that, at high pressure, Re is a good capsule material and that Fe
loss to Re under these conditions is minimal (e.g., Herzberg and Zhang 1997). We present here the
...
An Experimental Study of the Effects of Diagenetic Clay Minerals on Reservoir Sands
Diagenetic Clay Experimental Petrophysics Permeability Reservoir Quality
2011/12/2
Abstract: Despite substantial scientific research efforts, accurate determination of the petrophysical effects of clay minerals on reservoir sands remains problematic. Diagenetic clays such as smectit...
Solid-solid reactions mediated by a gas phase: An experimental study of reaction progress and the role of surfaces in the system olivine+iron metal
Solid-solid reactions olivine+iron metal
2012/4/1
The intergranular fluid involved in solid-solid reactions is tacitly assumed to be a melt or a (C-O-H-S-Cl-F)-bearing phase. We have studied the system olivine 1metal using dif-fusion couple experimen...
