Variability and Main Controlling Factors of Hydrocarbon Migration and Accumulation in the Lower Paleozoic Carbonate Rocks of the Tazhong Uplift, the Tarim Basin, Northwest China

Figure 9

Cross-plots of single-well cumulative oil production and average single-well production against distance from the main fault in the western region of the Tazhong Uplift. (a) Cross-plot for single-well cumulative oil production against distance from the main fault. (b) Cross-plot for 300-day average single-well production against distance to the main fault. Closer to the main fault, the overall hydrocarbon production is higher. Some oil and gas reservoirs that are too close to the strike-slip fault zone are not as rich as those at a distance of 200-500 m, which might be related to the upward hydrocarbon readjustment and remigration when close to the strike-slip fault zone.
