A study on how simultaneous sweeping rate affects high productivity seismic acquisition Available to Purchase

The main analytical focus in this study is the dynamic high productivity vibroseis acquisition (HPVA) method, which is based on multiple vibrator fleets that are subject to T-D rule. First, we conduct a simultaneous sweeping rate (abbreviated as SSR below) analysis on two typical, realistic HPVA projects. The results demonstrate that SSR ranges from 3% to 29%. Additionally, the total number of fleets, vibrator distributions, and individual T-D rule have an impact on both SSR and acquisition efficiency. Second, we propose an analytical method that make use of the quick simulation technique to evaluate the impact of different SSR on the HPVA result. The result shows that although SSR cannot give a precise indication of overall efficiency, it can provide us a guidance on how to optimize other factors such as number of fleets, distributions and so forth. At the HPVA planning stage, achieving a high simultaneous sweep rate alone should not be the only goal; instead, we should take a comprehensive approach that considers all relevant factors. Finally, the optimal method to distribute multiple fleets can be determined.
