The exergy analysis is a proper method for performance evaluation of industrial systems. A generic and detailed analysis of the GPCSs on the second gas pipeline of Iran  is made by the means of exergy. The two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. Steady state equations regarding the second law of ther...

The purpose of this study is the detection of lateral and vertical gradients of relative concentrations of compounds presented in oil. In addition, the detection allows us to assess potential drainage zones in a reservoir during the reservoir production by steam injection. In this paper, a new method for monitoring of steam chamber development in a 2D model was created and tested. The methodol...

Standing at 2.5 trillion barrels, Canada has the largest portion of the world’s ultra-heavy oil and bitumen resources. While shallow heavy oil reserves are extracted from pit mines, deeper reserves can only be extracted through wells. Production requires Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Simulation (CSS) methods. The optimal placement of wells defines the propagation of st...

The solvent–steam assisted gravity drainage is an oil recovery process that combines the advantages of thermal and miscible effects, it has been successfully tested, especially in Canada, where many heavy reservoirs are located. This method uses two parallel horizontal wells drilled one above other, upper injects steam solvent lower produces oil. not applied yet Brazil, there reservoirs, northe...
