Numerical simulation study on miscible EOR techniques for improving oil recovery in shale oil reservoirs

Journal of Petroleum Exploration and Production Technology, 2017
Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100–900 billion barrels of oil in Bakken only. However, the predicted primary recovery is still below 10%. Therefore, seeking for techniques to enhance oil

Investigation of enhanced condensate recovery potential in shale gas condensate reservoir by cyclic gas injection [PDF]

, 2017
When a shale gas condensate reservoir is produced, the pressure in the reservoir falls below the dew point pressure, and liquid condensate is formed in the pore space. The condensate can accumulate near the wellbore.

The characteristics and effects of Huff-n-Puff in shale with brine, aqueous surfactant solutions and CO2

Journal of CO2 Utilization
In this study, we evaluated the permeability damage and throughput potential of shale cores, focusing particularly on the damage water inflicts on shale permeability and the potential for hydrocarbon extraction using various injection media.

Research on Micropore Development Characteristics and Influencing Factors during CO2 Huff-n-Puff

Processes
CO2 huff-n-puff is an important method for the development of shale oil reservoirs. In this study, HPMI and NMR technology was used to characterize the pore distribution of the cores. The CO2 huff-n-puff experiment experiments were conducted to study the effects of injection pressure, soaking time, and heterogeneity on the CO2 huff-n-puff.

Integrated study on the applicability of CO₂-EOR in unconventional liquids rich reservoirs [PDF]

, 2018
Unconventional Liquids Rich Reservoirs (ULR) such as Bakken, Niobrara, and Eagle Ford have become the main target for oil and gas investors as conventional formations started to deplete and diminish in number.
