We present a framework for the application of multiscale science and technology to Enhanced Oil Recovery [EOR] by propagating physical models for wetting and flow from the molecular scale to the scale of pore networks in reservoir rock. The framework contains dedicated, computational and experimental platforms for performing calibrations at critical length scales. The appoach enables us to scie...

Primary oil recovery methods in Saskatchewan’s heavy oil basin extract 5 to 10% of the available resource with the vast majority left in the ground and recoverable only through Enhanced Oil Recovery (EOR) methods. Traditional EOR generates steam in surface facilities and injects it underground to mobilize the oil for production with considerable energy losses inherent in the process. R.I.I. Nor...

in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

The Biqian-10 block, located in Henan Oilfield of Sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. Therefore, it is a challenge to implement the conventional steam flooding. In order to improve the recovery of steam flooding, urea was used to assist steam flooding. Urea can decompose into CO2 and NH3, which are be...

Vietnam plans to develop dozens of new coal-fired power generation units over the next 20 years. In order to reduce emissions, it may appear necessary to dispose of these plants' CO2 by burying it in deep underground geological formations instead of releasing it into the atmosphere, using Carbon Capture and Storage (CCS) technology. We show that CCS has a technical potential in Vietnam. To disc...


 In the petroleum industry, Enhanced Oil Recovery (EOR) technology has been developed to obtain increased oil recovery from reservoirs. One of EOR methods is chemical using a surfactant known as flooding method. Surfactants have ability reduce interfacial tension between and water in rock matrix so that residual can be produced. There are several parameters affect performance surfactants,...

The recovery factor in unconventional reservoirs is typically 5–10%, with extensive hydraulic fracturing and infill drilling to maintain the production rate. Concurrently, rush towards decarbonization opening up new possibilities for CO2 utilization, enhanced oil (EOR) being one example. CO2-EOR presents an opportunity both financial gain through improved factors, as well reducing carbon footpr...

Nanoemulsions are a class of emulsions with a droplet size in the range of 50–500 nm and have attracted a great deal of attention in recent years because it is unique characteristics. The physicochemical properties of nanoemulsion suggests that it can be successfully used to recover the residual oil which is trapped in the fine pore of reservoir rock by capillary forces after primary and second...

Unconventional oils mainly heavy oils, extra heavy oils and bitumens represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to guarantee the viability of the oil recove...
