In this paper, taking the tight oil reservoir in Songliao Basin as the research object, a new mixed model of initial cumulative oil production of MFHWs was established, which can consider the geological factors and volume fracturing factors at the same time. Firstly, based...

...The basic thoughts in thick heavy oil reservoir fire flooding As to the four problems in the development of thick heavy oil reservoir fire flooding, corresponding adjustment techniques were studied, five technological ideas have been formed. Abstract Fire flooding process has been...

... thin oil rim which was not present during exploration. There were no sampling nor well testing done for the oil reservoirs. Due to emerging gas ullage limitation in the CPP, gas production was defered and the host government requested for the oil rim development. Subsurface study shows that the oil...

... is the composite control on water injection multiples for major oil reservoirs. In some areas with high injection volume, the fluid flow diversion should be fully taken into account, and both oil production and water flooding should be restored selectively for some well layers with potential to enhance the water...

... connectivity. Because solubility of asphaltenes in crude oil decreases with increasing gas/oil ratio (GOR) and asphaltene instability, tar mats may be formed by a late gas or light hydrocarbon charge into an oil reservoir. This tar mat is frequently far away from the location of the asphaltene instability...

... Abstract Guantao oil reservoir of the Bohai Bay, is characterized by low formation water salinity, high pore structure heterogeneity and flooding, which complicates the logging response, especially the low contrast of resistivity response. Traditional methods by resistivity fail to estimate...

... Abstract Pore volumes injected (PVI) has been found to be difficult to represent the longevity and intensity of water flooding in oil reservoirs. In order to find a better parameter to characterize fluid flooding, a new concept referred as to "flushing coefficient" has been proposed, which...
