The LArge Reservoir Simulator (LARS) was developed to investigate various processes during gas hydrate formation and dissociation under simulated in situ conditions of relatively high pressure and low temperature (close to natural conditions). To monitor the spatial hydrate distribution during hydrate formation and the mobility of the free gas phase generated during hydrate dissociation, a cyli...

Analysis of heterogeneous gas sand reservoirs is one of the most difficult problems. These reservoirs usually produce from multiple layers with different permeability and complex formation, which is often enhanced by natural fracturing. Therefore, using new well logging techniques like NMR or a combination of NMR and conventional openhole logs, as well as developing new interpretation methodolo...

[1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record failures that mobilized along extensional failure planes and transformed into long runout flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment causing extensional failure that drove successive scarp formation updip. This model is developed from three-dimensional seismic reflect...

In this work ternary CdZnS thin films were prepared by chemical bath deposition by doping CdS with different concentrations of Zn ions. The chemical bath comprised of cadmium nitrate [Cd(NO3)2], as a source of Cd 2+, zinc nitrate [ZnNO3)2]as source of Zn 2+ , thiourea [(NH2)2CS] as a source of sulphide ions [S 2]in the presence of ammonia [NH3] as a complexing agent. The competition mechanisms ...

Polycrystalline samples of Ca3-x Na x Co2-x Mn x O6 (x=0.0-0.5) have been prepared by the sol-gel cum combustion method using sucrose in order to investigate the effects of the coupled substitution of Na and Mn on Ca and Co sites on the transport properties of Ca3Co2O6(Co326). The products were characterized by Fourier transform infrared spectroscopy, powder x-ray diffraction (XRD), thermogravi...

It is known that the three important parameters: resistivity, capillary pressure, and relative permeability, are all a function of fluid saturation in a porous medium. This implies that there may be a correlation among the three parameters. There have been many papers on the approach to inferring relative permeability from capillary pressure data. However the literature on the interrelationship...

n-type silicon solar cell designs for high-efficiency commonly incorporate boron emitter formation. PECV-deposited boron diffusion sources are an alternative to primarily used boron gas diffusion sources. CVD layers are multi-functional allowing for diffusion of boron, surface passivation and contact formation by one single layer. In this case, these BSG layers are applied in a co-diffused cell...

We report the empirical discovery of an exceptionally high cross-B electron transport rate in magnetized plasmas, in which transverse currents are driven with abruptly applied high power. Experiments in three different magnetic geometries are analyzed, covering several orders of magnitude in plasma density, magnetic field strength, and ion mass. It is demonstrated that a suitable normalization ...
