The new CRM-like two-phase proxy-model for the process of oil field development

CRM models are a group of simplified mathematical models (proxy-models) based on the material balance equation, that allow solving various practical problems that arise during the development of oil fields. An important limitation of traditional CRM models, which significantly narrows the range of tasks to be solved, is the inability to account for changes in the water saturation of rocks, which limits their applicability only to periods with high water content of well products. This article presents a new author's CRM-like model that does not have this disadvantage. An algorithm for adapting such a model is also proposed. The results of numerical experiments on synthetic hydrodynamic models demonstrating better quality of solutions compared to the CRMP model are presented.
