Oil-reservoir management using measurements and control techniques have been in use by oil and gas industries to improve the production and maintenance of the existing oil reservoirs. In the course of this project the applications of UWB radar systems and techniques to acquire near real-time information about the oil reservoir conditions are studied. Various oil reservoir structures such as oil...

thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. when high frequency is used for heating, it is called electromagnetic (em) heating. the applications of em heating for heavy-oil reservoi...

asmari formation was deposited in the foreland zagros basin (southwest iran). in this research, biostratigraphy related to the asmari formation in north of khorram abad, robat namaki section, is discussed. in the studied stratigraphic section, the asmari formation overlies the shahbazan formation and underlies gachsaran formation and consists of cream to gray medium to thick limestone and marl....

In oil production waterflooding is a popular recovery technology, which involves the injection of water into an oil reservoir. Studies on model-based dynamic optimization of waterflooding strategies have demonstrated that there is a significant potential to increase lifecycle performance, measured in Net Present Value. However, in these studies the complementary desire of oil companies to maxim...

Evaporative fractionation of petroleum by gas injection over oil was established by Thompson. In this process he could fractionate reservoir petroleum to paraffin rich condensate in the shallow reservoir and aromatic rich residual oil in the original reservoir. In the present work attempt has been made to test fractionation by heating crude oil in a closed system to build up adequate vapour pre...

One of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. Several parameters should be optimized in a fluid injection process. The usual optimizing methods evaluate several scenarios to find the best solution. Since it is required to run the reservoir simulator hundreds of times, the process...

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...

Abstract: The oil recovery factor from shale oil remains low, about 5 to 7% of the oil in place. How to increase oil recovery from shale oil reservoirs is attracting more and more attention. CO2 huff-and-puff was historically considered one of the best approaches to improve the oil rate. Most previous simulation studies have been based on dual porosity, but simulation results from dual-porosity...

Predicting oil recovery efficiency of a deepwater reservoir is a challenging task. One approach to characterize a deepwater reservoir and to predict its producibility is by analyzing its depositional information. This research proposes a deposition-based stratigraphic interpretation framework for deepwater reservoir characterization. In this framework, one critical task is the identification an...
