Because of different behavior of reservoir water and dam material, the determination of hydrodynamic pressure during earthquake is very complicated. Thus, different formulations have been presented for modeling of the dam reservoir system under dynamic loading such as earthquake. These formulations can be categorized into two general groups, which are Lagrangian and Eulerian, each having advant...

Bubble point pressure is an important parameter in equilibrium calculations of reservoir fluids and having other applications in reservoir engineering. In this work, an artificial neural network (ANN) and a least square support vector machine (LS-SVM) have been used to predict the bubble point pressure of reservoir fluids. Also, the accuracy of the models have been compared to two-equation stat...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

The blood flow teas measured continuously in the intact vortex vein of the anesthetized rabbit using an ultrasonic Doppler -flowmeter toith a frequency response of approximately 4 Hz. Blood flow correlated well ivith perfusion pressure (arterial pressure minus intraocular pressure). The intraocidar pressure was changed stepwise by perfusion from a saline reservoir, Tonometry teas performed tuit...

This paper presents a mathematical model for transient flow of the non-Newtonian power-law fluid in double porous media and fractal reservoir. By using Douglas-Jones predictor-corrector method, we obtain the solution for the constant rate condition at a single well in an infinite reservoir. The flow behavior is also analyzed. Finally, we discuss the pressure response to the various parameters. ...

OBJECTIVE To analyze the urodynamic characteristics of neobladders, we conducted a pressure-flow study in patients with orthotopic urinary reservoirs. PATIENTS AND METHODS From 1986 to 1996, 90 patients underwent bladder replacement following cystectomy, using a right colonic, ileocolic, ileal, or sigmoid colonic segment. The subjects were 38 patients (31 men and 7 women) with stable urinatio...

Pore-pressure variations inside producing reservoirs result in excess stress and strain that cause time shifts of reflected waves. Inversion of seismic data for pressure changes requires better understanding of the dependence of compaction-induced time shifts on reservoir pressure reduction. Here, we investigate pressure-dependent behavior of P-, S-, and PS-wave time shifts from reflectors loca...

Concrete faced rockfill dams (CFRDs) are among the structures that due to their advantages such ease of construction and low execution costs,have attracted more attention nowadays.Due to the fact that during large earthquakes,the hydrodynamic pressure will be large and cannot be ignored,the main purpose of this research is to apply reservoir hydrodynamic pressure of dam reservoir caused by the ...

Gas reservoirs with low permeability (k<0.1 mD) are among the unconventional reservoirs and are commonly termed as "Tight Gas Reservoirs". In conventional gas reservoirs that have high permeability, the flow of gas is basically controlled by the reservoir permeability and it is calculated using the Darcy equation. In these reservoirs, gas flow due to gas diffusion is ignored compared to Dar...
