Foam injection is a promising method to improve sweep efficiency for gas flooding in enhanced oil recovery (EOR). The effect of oil on foam is a complex phenomenon and for this reason three phase foam simulations have shown to be difficult in the past. Initially the objective of this simulation study was getting a better understanding of relating composition paths for foam displacements on the ...

â â â  â â â  abstract â  using a structural var with block exogeneity, diagonality and identifying restrictions, this paper analyzes: first, the macroeconomic linkages among the oil price, u.s. output, interest rate, money supply, general price level and exchange rate and second, the relationships of the macroeconomic variables with the price indices of ten international nonfuel commodity grou...

Oil price shocks are the main source of macroeconomic fluctuations in oil exporting countries. It is believed that appropriate monetary policy can help to stabilize these unwanted variations toward optimal allocations. A stochastic dynamic general equilibrium model featuring the properties of both cost push and wealth effect transmission channels is developed for the Iranian economy. In thi...

This paper considers an application of the Markov switching vector error correction model to analysis long-run and short-run dependence Russian real GDP exchange on oil prices. An algorithm for estimation with a priori information state hidden chain in some periods time is provided. It shown that period 1999–2018 two different regimes are well defined: slow adjustment rate sharp reaction respon...

This paper explores the short-run price-inventory dynamics in the presence of different shocks. Classical competitive storage model states that inventory decision considers both current and future market condition, and thus interacts with spot and expected future spot prices. We study competitive storage holding in an equilibrium framework, focusing on the dynamic response of price and inventor...

The way in which vectors distribute themselves amongst their hosts has important epidemiological consequences. While the role played by active host choice is largely unquestioned, current knowledge relates mostly to the innate response of vectors towards stimuli signalling the presence or quality of their hosts. Many of those cues, however, can be unpredictable, and therefore prevent the incorp...

Heavy-duty vehicle hydrodynamic mechanical automatic transmission shifting operation system was designed, mathematical model of its simplified hydraulic system was established and simulation model of shifting operation system was established with AMESim, the simulation experiment was carried out, then oil pressure curves of each clutch hydraulic cylinder were obtained when giving forward gear o...

A recent paper by Bernanke, Gertler and Watson (1997) suggests that monetary policy could be used to eliminate any recessionary consequences of an oil price shock. This paper challenges that conclusion on two grounds. First, we question whether the Federal Reserve actually has the power to implement such a policy; for example, we consider it unlikely that additional money creation would have su...

In the process of rapid social and economic development, demand for oil related industries is more large. The continuous increase exploitation causing some fields to gradually enter period special high water cut development increasing difficulty exploitation. Therefore, how improve recovery key question that relevant personnel think solve. Based on this, this paper mainly describes channel sand...
