A generalized framework for Capacitance Resistance Models and a comparison with streamline allocation factors

The results lead to the following findings: 1) there is a fair correlation between CRM interwell connectivities and streamline allocation factors but the CRM values correspond to the pressure support and can connect more distant injector-producer pairs. The streamline allocation factors reflect water front advance and are largely limited to adjacent wells; 2) the CRM is significantly less sensitive to noise in flowrates than in BHP measurements; and 3) Different CRM representations show important performance differences based on reservoir heterogeneity, input variations and noise levels.
