Effects of oil viscosity on waterflooding: A case study of high water-cut sandstone oilfield in Kazakhstan

Open Geosciences, 2020
After a sandstone oilfield enters the high water-cut period, the viscosity of crude oil has an important influence on remaining oil distribution and waterflooding characteristics under the same factors of, e.g., reservoir quality and development methods.

The Fish Oil Story Remains Fishy [PDF]

Circulation, 2010
There is substantial evidence, mostly observational, that diets that include fish reduce the risk of coronary heart disease.1,–,4 Yet, a major question remains as to whether this benefit is due entirely to the omega-3, or long-chain, n-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and/or other nutrient contents in ...

Simulation analysis of the mechanism and influencing factors of remaining oil secondary enrichment in ultra-high water cut fault block reservoirs

Energy Exploration & Exploitation, 2023
After the near-abandoned production wells in the high part of the fault block reservoir are closed for a period of time, the remaining oil in the low part will accumulate at the fault in the high part to produce secondary enrichment. At present, research
