... Abstract This study makes an attempt to generalize the integrated modeling tools used by the authors in practice on the basis of the following criteria: the volume of the initial data, the integration mechanism, constraints and assumptions. Various types of integrated models are compared...

... of the Capacitance Resistance Model (CRM) Al-Yousef et al 2006 [10] , developed this model based on the assumption of viewing the reservoir as a system that takes an input signal an produces an output. This idea is similar to the one introduced earlier by Bruce 1943 [1] . However, this model is different...
