The paper notes the necessity of controlling the wellbore spatial position directly during drilling and transmitting information via the wireless electrical communication channel of the well bottom with the well head. The existing means of measuring a borehole curvature zenith angle are considered, their disadvantages are shown. The scheme of the frequency sensor of the zenith angle is given. The design and principle of operation of the sensor are described. The results of the sensor experimental study are presented. The main functional dependence of the tuning fork Q-factor on the zenith angle value of the borehole curvature is revealed. It is shown that the proposed sensor has increased measurement accuracy. Recommendations for eliminating additional error are given.

 

Keywords: zenith angle; borehole curvature; tuning fork; quality factor; frequency response; bandwidth; natural frequency; drive and vibration pickup system; SOI technology.

To solve the problem of determining the volumetric concentrations of the gas condensate wells production components, a method is used based on the reaction of a microwave resonator to a flow of a gas condensate mixture – gas, water and hydrocarbon condensate passing through it, taking into account the differences in their dielectric constants and the fact that only water absorbs microwave energy of the resonator. When extending the method to the production of oil wells, they also face limitations: oil contains sulfur compounds, which also lead to the absorption of microwave energy. The paper analyzes the losses caused by oil and the areas of application of the method when replacing hydrocarbon condensate with oil.

 

Keywords: gas-liquid flow; microwave resonator; the dielectric conductivity; measurement error; hydrocarbon condensate; oil; consumption.

The paper describes possible risks in the oil and gas industry when using artificial intelligence technologies. The digital economy is becoming a key element of the competitiveness of the Russian fuel and energy complex. The transition from export-raw materials to resource-innovative development is the first stage of the implementation of the digital modernization strategy. The oil and gas complex currently has the world's largest mineral resource base, developed infrastructure, qualified personnel and significant innovation potential, including the ability to implement digital technologies and high-conversion industries, which implies a large-scale, fast and efficient return on invested financial resources, new business models to maintain the leading positions of hydrocarbons production in the long term. These capabilities can only be achieved through the introduction of technologies based on the acquisition and processing of large amounts of data, machine learning and digital twins in order to minimize uncertainty factors and risk assessment, as well as to prevent possible abnormal situations and minimize damage caused by technological regimes violation. Uncertainty factors can make it difficult to predict the financial, social, logistical and other business conditions, therefore, long-term major projects may not be implemented. The paper also considers the reasons for the current conservative policy on the innovative products promotion in the oil and gas industry as well as the integration of digital and technological decision-makings that improve the efficiency of management of production facilities of the production infrastructure. The main possible risks and the degree of their risk impact on the project are presented. Possible measures to reduce risks and their consequences are presented on the example of creating a high-performance intelligent system for preventing drilling of oil and gas wells, which allows creating a basis for the transition to unpopulated technologies for preventing accidents and remote work in oil and gas fields.

 

Keywords: artificial intelligence; system; risk; damage; intelligent technologies; big data; drilling; oil and gas production.

The process of gasoline blending is an important final stage in the overall technological chain of gasoline production. The technological costs of compounding are determined by the efficiency of maintaining the hydrodynamic mode of mixing gasoline components, control, optimization of the fuels mixing components, optimal control and regulation. The development of a mathematical model, the formulation of the problem of optimization and control over gasoline mixing in real time (online mode) is one of the important stages in the creation of a distributed control system (DCS). The paper presents a mathematical model of gasolines mixing online optimization, taking into account the conditions of uncertainty of the technological regime parameters. The presented mathematical model takes into account the parametric uncertainty of the gasoline mixing process in real time when constructing control algorithms in the DCS. A neural network model for solving the problem of forecasting and optimizing a gasoline blending control system in real time is presented.

 

Keywords: gasoline mixing; intelligent system; optimization model; gasoline mixing recipe; mathematical description; optimality criterion; limitation; parametric uncertainty; neural network.

The paper is devoted to solving the problems of system modeling based on the method of dynamics of averages of the theory of the Markov random processes, the functioning (operation) of the service for the synthesis of special software (SSS) of large automated control systems (ACS), including automated control systems for oil and gas enterprises, in conditions of uncertainty and risk. The operation of the SSS synthesis service is considered at the stable operation stage – the stationary operation of the Markov chain. A multi-criteria dispersion model for assessing the risk of their functioning is proposed using the average numbers of the objects states (elements of the systems under consideration) and the intensities of their transitions from state to state. The models of efficiency and risk assessment for selecting the optimal strategy (functioning option) are proposed according to the selected set of formed compromise criteria and restrictions.

 

Keywords: transition intensity; average state size; multi-criteria assessment; risk; operation strategy; medium dynamics; the Markov chain stationary mode; special software; remote software development service.

Using the results of well tests, the problem of factorization of flow rate profiles data of production and injection wells completed in a two-layered reservoir is formulated. This problem is ill-posed, and the process of adding information in order to solve it is required (regularization). Several methods of deterministic regularization based on 𝓁2-norm minimization of the unknown vector are considered. It is shown that such approaches do not take into account the petrophysical properties of the reservoir and cannot cover all possible factorization combinations. The Bayesian regularization is proposed to factorize the flow profile data. According to this method, all relative factors are defined by the corresponding probability distribution functions. Core studies are used to determine the joint probable distribution of rock permeability and porosity. Layer productivity ratio distributions are calculated separately for each well based on its log interpretation data. The Bayesian statistical inference is used to obtain the general drawdown ratio distribution for the entire field. This approach was tested on real data obtained from three fields.

 

Keywords: regularization; the Bayes’ theorem; statistical inference; well test; flow profile; productivity index; injectivity index.
