gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

in this research, feasibility study of integrating thermal desalination unit with gas turbine (gt) has been investigated using retrofit and grass root design techniques  for lavan island oil refinery which is located in persian gulf. according to computed parameters on developed code for the power generation unit no.1 using ees (engineering equation solver) software, thermal efficiency of the g...

Introduction EOR This word literally means enhanced oil recovery and in the oil industry area used as extraction of oil reservoir that deals by advanced industrial techniques to harvest of reservoir heavy and semi-heavy oil [1]. In Canada 1.2 million barrels a day, Venezuela's 600,000 barrels per day and in China 150,000 barrels per day produced oil of heavy oil reservoirs. Canada, America, Ven...

We consider parallel computing technology for the thermal simulation of multicomponent, multiphase fluid flow in petroleum reservoirs. This paper reports the development and applications of a parallel thermal recovery simulation code. This code utilizes the message passing interface (MPI) library, overlapping domain decomposition, and dynamic memory allocation techniques. Its efficiency is inve...

Integrated solar thermal steam generation and heavy-oil recovery projects have garnered interest because of their ability to decrease the variability of steam generation costs arising from fluctuations in natural gas prices as well as life-cycle carbon dioxide emissions. The viability of a solar thermal steam generation system (with and without natural gas back-up) for thermal enhanced oil reco...

Nonionic surfactant-stabilised oil-in-water emulsions offer a potentially useful vehicle for transporting heavy crude oils from oilfields to refineries or distribution terminals. Prior to refining, separation of the oil from the emulsion is necessary. Previous studies have suggested that heating the emulsion is sufficient for destabilisation and recovery of the oil. The present work examines th...
