Development of hydrocarbons transportation pipeline systems and their ageing cause a contactless system creation providing express-diagnostics of pipelines pre-breaking state. Low contrast response from the damaged pipeline sections is allocated by the methods of interpretation of abnormal magnetic field. The problem of ultimate automation of interpretation procedure with estimation of experts’ possible verification exclusion is considered. Despite this idea attractiveness from the management point of view, the paradoxical nature of the problem possible solution is substantiated.

Keywords: pipeline; interpretation; diagnostics; magnetic field; automated system; model; functional; minimization.

The development and digital implementation of mathematical models of production and technological processes are effective if they are involved in the operating modes of oil production control and management. Efficiency increase of ESP-equipped well operational modes is associated with the creation of specialized models that reflect complicating factors specific impact. That kind of models should be implemented within the information resources of the production dispatching services, reliably reflect the evolution of complicating factors, predict the immediate aftereffects and be used in decision-making schemes.

This paper describes an example of constructing of a well’s similar barometric model with a frequency-controlled ESP that can be used in the tasks of monitoring, predicting and anticipating the gas factor impact.

Keywords: ESP-equipped well; gas factor; complicating factors; non-linear inflow; limitations; frequency stabilization.

The effective application of the cyclic waterflooding technology to increase oil formations productivity as well as determination of this process optimal strategy, asumes the existence of a fairly simple and at the same time an accurate model of the control object. The object in this case means a system consisting of the equipment of reservoir pressure maintenance system and the most productive reservoir. That’s why obtaining a model is usually a difficult task. At the same time, one of the examples of the simplified approach is the description of wells work in the form of pressure recovery curves (PRC). Such data serve as a foundation for constructing more complex hydrodynamic reservoir models and thus contain important information about the processes in the well-reservoir system. The automatic control theory (ACT) considers PRC a time characteristic, namely, a transient characteristic, which reflects the basic properties of an object. This makes it possible to identify the object under study as a transfer function. The application of the automatic control theory’s tangent method is considered to solve the problem. The results of the injection wells identification and their comparison with the independent studies results are presented.

Keywords: cyclic waterflooding; oil recovery factor; pressure recovery curve; efficiency; modeling; control object identification; transfer function; pulse duration.
