| 3 | Input signal design to estimate interwell connectivities in mature fields from the capacitance-resistance model显示文摘Interwell connectivities are fundamental parameters required to manage waterfloods in oil reservoirs. Data-driven models, such as the capacitance-resistance model(CRM), are fast tools to estimate these parameters from time-correlations of input(injection rates) and output(production rates) signals. Noise and structure of the input time-series impose limits on the information that can be extracted from a given data-set. This work uses the CRM to study general prescriptions for the design of input signals that enhance the information content of injection/production data in the estimation of well-to-well interactions. Numerical schemes and general features of the optimal input signal strategy are derived for this problem. | Gustavo A.Moreno Larry W.Lake | 2014 | Petroleum Science2014，11，4： | 0 |
