... Abstract D block is a heavy oil reservoir that was first developed in 1997 with the method of Cyclic Steam Stimulation (CSS). After nearly 20 years’ development, several technical challenges have shown: the reservoir pressure decreased from 7.4MPa to 2.9MPa, and the Steam Oil Ratio (SOR...

... way to maximize recovery efficiency with in low-permeability heavy oil reservoirs. It also has important strategic significance for development and exploration promotion of these unconventional reservoirs. proppant oil reservoir fracturing fluid Efficiency viscosity reducer viscosity...

... Abstract Kuwait is in the process of developing the deeper heavier oil reservoirs as part of Kuwait's national oil production strategy and KPC strategy 2040. This is in order to increase the oil production capacity for the next decade. The enhanced recovery of heavy oil assets needs a high...

... to produce due to its high viscosity hence low mobility underground. Kuwait strategy is shifting focus to these types of oils since conventional medium oil and other less-quantitative-light-oil reservoirs are continuously depleting. The study's interest is directed towards a specific type of EOR oil, which...

... Abstract Steamflooding is an effective and commonly-used thermal recovery technique for the development of heavy oil reservoirs. In the Pai-601 block of Chunfeng Oilfield where the viscosity is over 50000 mPa.s with the layer thickness only ranging from 4 to 10 m, traditional thermal recovery...

... Abstract Most oil reservoirs in Changqing Oilfield area are low permeability. After several ten years of production, the effect of water flooding becomes worse and worse as the reservoir enters middle development stages. CO 2 flooding is an important method for oil fields in the future...

... Abstract The fluids injection in oil reservoirs has the function to supplement the natural energy and in some cases is used to interact with the rock/oil system of reservoir, creating favorable conditions for oil recovery, for example lower interfacial tension, oil swelling, oil viscosity...

... mechanisms have been studied to increase the recovery of these types of reservoirs. This study analyzes the effect of bottom-hole electric heating on the production and recovery factors of extra-heavy oil reservoirs. The study was carried out by numerical simulation, analyzing the most influential parameters...
