The basis of reservoir physics and hydrodynamic modelling

• training is conducted in the form of online training which implies audiovisual delivery (presentation) and active involvement of trainees;
• discussion of problems and questions;

• acquiring basic knowledge about types and functions of hydrodynamic models;
• learning skills of quality assessment and laboratory data preprocessing necessary for hydrodynamic modelling.
• skills to select the method of model initializing, methodology of history matching;
• skills to conduct an expert appraisal of a model;
