When comparing the condition of a production facility at various stages of development, it is important to pay attention to differences related to their organization and regulation levels. Such an approach allows for reliably identifying critical time intervals of production indicators, which forms the basis for conducting dynamic analyses during these intervals and implementing procedures that enable the refinement of recoverable reserves. Efficient development of oil and gas fields requires timely and well-founded decisions for regulating technological processes aimed at intensifying oil and gas production during the transition period. Decisions regarding the selection of enhanced oil recovery strategies mainly depend on determining the characteristic phase of the field’s development. Most existing analysis methods do not consider the evolutionary mechanism of the reservoir system during field development, and various factors affecting oil production complicate the analysis process and make well-founded decision-making more difficult.
