the effect of underground cavities in site seismic response was studied over the subway tunnels that are under construction in the city of karaj, using ambient noise measurements as well as numerical modeling. the idea for this research comes from the observation of differences in experimental site transfer function, calculated on more than 100 locations of the city, for the areas near the unde...

The term “geomechanics” means different things to people. We assert that in the petroleum industry broad consensus for a definition would probably be something like this: Geomechanics is discipline investigates rock mechanical behavior subsurface (i.e., at wellbore wall, overburden, cap rock, and/or reservoir) under present-day in-situ stress and pore pressure conditions or those changed throug...

Gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. They are widely used in various industrial applications such as oil extracting in petroleum industries. Gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, chur...

The primary objective of our current research is to develop a computational test bed for evaluating borehole techniques to enhance fluid flow and heat transfer in enhanced geothermal systems (EGS). Simulating processes resulting in hydraulic fracturing and/or the remobilization of existing fractures, especially the interaction between propagating fractures and existing fractures, represents a c...

Analytical solutions are developed for the response of saturated porous media under twodimensional plane strain condition. Depending on the nature of loading vis-à-vis the characteristics of the media, different formulations (fully dynamic, partially dynamic, quasi-static) are possible. The solutions for these formulations are developed in terms of non-dimensional parameters. The regions of val...

One way to include fracture and fragmentation when analyzing loaded mechanical systems is based on the DEM, [2], [3]. In recent years this approach was adopted in geomechanics and civil engineering to model fracture in elastic-brittle materials, e.g. [1] and [5]. Using this approach, the material is considered as being fully discontinuous and made up by assembling and bonding adjacent discrete ...
