This paper presents a 2D model of the Ghawar field and investigates flow behavior in during secondary tertiary recoveries using simplified well scheme. For latter, focus is on chemical Enhanced Oil Recovery (EOR), polymer solutions. The difference efficiency between recovery influence factors such as degradation are analyzed presented. Furthermore, oil viscosity factor investigated placement st...

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...

A systematic study has been performed employing the use of a cationic surfactant didodecyldimethylammonium bromide (DDAB), an anionic surfactant sodium lignosulfonate (SLS) and water for Enhanced Oil Recovery (EOR) from the underground porous media of the depleting oil field of Naharkotiya, Duliajan, in the Upper Assam basin, India. The strong electrostatic interaction between the oppositely ch...

In many practical flow situations solutions of flexible polymers are found to exhibit a well-known non-Newtonian viscosity enhancement effect. This is likely to be due to extensional components in the flow field, which can cause flexible polymer molecules to stretch and orientate, causing an increase in the extensional viscosity. This viscosity enhancement is important in many industrial applic...

recovery factor is an important parameter in determining commercial viability of the oil reservoirs. wettability is a major factor that affects oil recovery. therefore, changing rock wettability may enhance oil recovery. in this paper, the effect of polysilicon nanoparticles on wettability change of iranian carbonate reservoir is investigated. to assess this, hydrophilic changes of carbonate ro...

Water-soluble polymers have been used for a wide variety of applications due to their versatility. Watersoluble polymers are found in many different industries including agriculture, food, plastics, pulp and paper, mining, petroleum, textiles, and waste water treatment. Often, they are used as both processing aids and components of final products. Addition of water-soluble polymers to industria...

Polymer flood gains expansive popularity as a promising EOR method in various oilfields worldwide. However, there are still substantial amount of resources underground after polymer application. To further enhance oil recovery, secondary chemicals are sometimes utilized to sweep the remaining hydrocarbons to maintain the consistent development of oilfields. In this paper, a series of experiment...

Nanotechnology has various applications in oil and gas industry such as enhanced oil recovery (EOR). The main challenge in using nanoparticles in EOR processes is their stability in harsh conditions such as high temperature, high pressure, and intermediate to high salinity. However, most of the recent experimental works have been performed under unrealistic conditions such as the use of distill...
