... Abstract The continental shale oil reservoirs usually have strong heterogeneity, which make the law of fracture propagation extremely complex, and the quantitative characterization of fracture network swept volume brings great challenges. In this paper, firstly, the grey correlation analysis...

... of the reservoir are completed. The results show that the DLPI of Bohai Sea heavy oil reservoir are following: water cut < 60 % indicates the trend is flat; water cut between 60 ∼ 80 % illustrates the slow growth (water cut 80 % is 2.5∼3 times); water cut > 80 % shows rapid growth (water cut 95% is 5.5∼6...

... Abstract Tight sandstone reservoirs are an important petroleum resources in recent years. Hydraulic fracturing is widely used to stimulate development of tight sandstone oil reservoirs by creating underground fractures, but the low flowback rate of fracturing fluid leads to the water blocking...

The expanding process of the steam chamber and the production performance in different stages are compared between SAGP and SFGD...

... Abstract The Triassic Yanchang formation is rich in tight oil resource at Ordos Basin. The oil sandstone and oil shale of Chang 7 member are widely spread in the basin and have huge potential in oil production. Due to low porosity and low permeability, producing oil from tight oil reservoir...

... Abstract Oil reservoirs are considered good storage structures for CO 2 geological storage. With the right selection of candidate reservoir, injection of CO 2 into tertiary and depleted oil reservoirs can result in enhanced oil recovery (EOR) and permanent sequestration of CO 2 underground...

... Abstract A series of light oil fields which are characterized by shallow burial, good physical property have been discovered through latest exploration in Baiyun Depression of Pearl River Mouth Basin. However light oil reservoir is "Atypical bright spot" reservoir. The light oil-bearing and gas...
