China has written ＂The state respects and protects human rights＂ into its constitution, thus opening up a new period of constitutional construction and human rights cause. This great term ＂human rights＂ does not only contain specific rights that can be put into practice but also carry dignity, equality, freedom and other value systems and moral requirements.展开更多

The recovery rate is low so that it becomes a challenge for production. Time-lapse seismic data is studied to improve the oil recovery for this field, This feasibility study analyzes the possible time-lapse seismic attribute spatial distribution using dynamic data and the reservoir model to determine the optimum time to acquire a new seismic survey. Based on the study, it is found that the time-lapse seismic response for this unconsolidated sand has a strong signature due to solution gas when the reservoir pressure is below the bubble point. This indicates that acquiring a new survey after 10 years of production is appropriate for a time-lapse seismic application.展开更多
