The behavior of two-dimensional binary and ternary amphiphilic fluids under flow conditions is investigated using a hydrodynamic lattice-gas model. After the validation of the model in simple cases (Poiseuille flow, Darcy's law for single component fluids), attention is focused on the properties of binary immiscible fluids in porous media. An extension of Darcy's law which explicitly admits a v...

Strains of Salmonella typhimurium were studied in the ligated rabbit ileal loop model to gain insight into the mechanisms whereby bacteria which invade the gastrointestinal mucosa evoke fluid exsorption. The organisms employed differed in various biologic attributes including the ability to invade the ileal epithelium, multiply within the mucosa, elicit an acute inflammatory reaction, and disse...

When a nonviscous liquid is injected into a porous medium already filled with a viscous fluid the system can be found in two different regimes: one where the dominant forces are of capillary nature and another where the viscous forces are predominant. The theoretical description of such system is based on two models: diffusion-limited aggregation (DLA) 1 and invasion percolation . DLA describes...

With the characteristics of low fracturing pressure, little damage to reservoirs, and assuming role carbon storage, supercritical dioxide (SC-CO2) is suitable for development unconventional oil gas resources. Based on tensile failure mechanism rocks, this paper establishes a thermal-fluid-solid coupling initiation pressure model SC-CO2 fracturing. Using model, changes in formation temperature p...

Abstract Reservoir formation damage is a major problem that the oil and gas industry has to mitigate in order maintain supply. A case study presented identifies impacts of their causes Nubian ‘C’ hydrocarbon reservoir within Sidki field located Southern Gulf Suez, Egypt. In addition, mitigation program was designed implemented involving an effective stimulation treatment for each well experienc...

When drilling or exploiting fractured formations, gas fluid displacement and invasion often occur, is very subtle difficult to find. The in the fracture enters wellbore arrives near wellhead with fluid. Improper treatment may lead serious accidents such as lost circulation blowout. In this study, using computational dynamics (CFD) simulation software for modeling grid generation, based on volum...

Abstract Nowadays, as accepted as the era of information or digital, time has changed and has invited all people to a new world in which everybody must define himself. Avoiding from getting benefit from this human progress is useless; Rather, we must know this great technology best and adapt ourselves with its consequences. In fact, in many countries and among many nations there had been peopl...
