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...

Low-salinity water-alternating-CO2 (CO2-LSWAG) injection has been widely studied and employed due to its capability promote enhanced oil recovery (EOR). However, there is no consensus on the dominant mechanisms for in carbonates extreme complexity of oil–brine–rock interactions. This work proposes a comparative investigation physicochemical geochemical effects continuous CO2 CO2-LSWAG immiscibl...

In regions where water resources are scarce and in high demand, it is important to safeguard against contamination of groundwater aquifers by oil-field fluids (water, gas, oil). this context, the geochemical characterisation these critical so that anthropogenic contaminants can be readily identified. The first step characterising pre-development fluid signatures (i.e., those unmodified hydrocar...

Residual oil zones (ROZs) could present a new, potentially large and commercially viable resource for Australia provide an avenue geological storage of carbon dioxide (CO2) through CO2 enhanced recovery (CO2-EOR). These reservoirs, which can contain moderate amount residual resemble water-flooded fields, be associated with conventional fields (brownfields) or occur no main pay zone (greenfields...

Fully compositional and thermal reservoir simulation capabilities are important in oil exploration and production. There are significant resources in existing wells and in heavy oil, oil sands, and deep-water reservoirs. This article has two main goals: (1) to clearly identify chemical engineering sub-problems within reservoir simulation that the PSE community can potentially make contributions...

Alaska holds more than 68 billion barrels of proved oil reserves and 36.7 trillion cubic feet natural gas with some special conditions such as proximity to permafrost, making Alaskan petroleum unique. The low temperature in shallow reservoirs prohibited hydrocarbons’ ideal maturation, thereby generating several heavy viscous accumulations this state. This also limits the enhanced recovery (EOR)...

In this work, polymeric materials designed for enhanced oil recovery (EOR) were evaluated their intended application. Properties including viscosity, flow through porous media (resistance factor and residual resistance factor), heavy displacement (incremental recovery) assessed terpolymers of 2-acrylamido-2-methylpropane sulphonic acid (AMPS), acrylamide (AAm), acrylic (AAc). The same propertie...
