The article discusses the difference between the adaptive geological model and the traditional deterministic one, which is based on the manual work of geologists in the pre-computer era. Today, the deterministic approach to modelling has outlived its usefulness. Computer simulations use other methods. Therefore, it is necessary to break away from the deterministic tradition in order to move on. The adaptive geological model is a mathematical function, the purpose of which is not at all to display actual information about the structure of a petroleum reservoir as accurately as possible, but to predict its structure in undrilled zones. The adaptive approach proves that it is not necessary to obey the facts for a successful forecast. This is often even harmful, since the geological structure of the petroleum reservoir at the points where the wells are drilled is known without modelling. Just as in the regression analysis, it is not at all necessary that the function passes exactly through all the actual points, it is not necessary for the geological model of the petroleum reservoir to fully reproduce the actual data. This is the fundamental feature of the adaptive geological model.
