The fracture-controlled matrix unit is commonly found in low-permeability fractured reservoirs. Due to the permeability difference between fracture system and system, a large amount of oil will remain during traditional water injection development, thus limiting reservoir productivity. However, special imbibition mode provides breakthrough for secondary recovery. In this paper, based on model s...

Gas injection has already proven to be an efficient shale oil recovery method successfully tested all around the world. However, gas-enhanced methods have never been implemented or for greatest Siberian formation yet. This article proposes numerical simulation of a hydrocarbon gas process into horizontal well with multiple hydraulic fractures perforating Bazhenov in Western Siberia characterize...

The research area of tight sandstone oil reservoirs was selected, a numerical model the reservoir developed, and study development options influencing factors carried out to analyze influence different methods, physical engineering parameters on dynamics. Study shows that two main limiting efficient are properties formation energy. Fractured horizontal well injection huff puff can effectively i...

Due to the compactness of shale reservoir matrix and high conductivity fractures, hydrocarbon gas injection huff puff method or displacement is most realistic technology improve oil recovery. The diffusion mechanism plays an important role in development; therefore, it crucial figure out factors influencing diffusion, which could enhance In this paper, a physical simulation experiment designed ...

With immense potential to enhance oil recovery, CO2 has been extensively used in the exploitation of unconventional tight reservoirs. Significant variations are observed occur oil’s composition as well its physical properties after interacting with CO2. To explore impacts on extraction efficiency, two different types crude (light and heavy oil) huff-n-puff experiments. Moreover, numerical simul...
