The article introduces a series of publications about new tools created by Rosneft to improve the performance in infrastructure facilities engineering for the development of oil and gas fields and implementation of general exploration and production projects, such as etalon projects, platform solutions, and information modeling (3-5D, BIM). The article describes the main provisions of the etalon engineering methodology, including the results of a comprehensive analysis of the potential for unification of well pad options for RN-Yuganskneftegas by applying digital etalon projects. A digital etalon project is a completed engineered facility, with the exception of foundations/pile foundations, with unified design solutions, to be applied when creating information models of blocks (modules) of complex design solutions in a number of options sufficient for designing all possible configurations of a facility limited by its scope of application. The paper demonstrates that the methodological developments of Rosneft Oil Company will ensure the creation, at the industry level, of examples of mass-built oil and gas production facilities to improve the performance of hydrocarbon exploration and production projects, and the Rosneft Group companies will be able to reduce the project implementation time by optimizing the timing of scheduling the planned needs for material and technical resources and look-ahead purchase thereof simultaneously with the end product development based on pre-order specifications formed on the basis of the selected etalon project. It is expected that the etalon engineering methodology will also allow a significant reduction of the time for building 3D models of well pad infrastructure and for aligning the end products in accordance with regulatory requirements, for accepting the end products, and will reduce the time for approval of design documentation, and also improve the end products quality by eliminating collisions in the end products development through 3D modeling, will reduce the amount of uncompleted construction projects by minimizing the supply risks of material and technical resources, and will ensure the unification of the nomenclature of material and technical resources.The article introduces a series of publications about new tools created by Rosneft to improve the performance in infrastructure facilities engineering for the development of oil and gas fields and implementation of general exploration and production projects, such as etalon projects, platform solutions, and information modeling (3-5D, BIM).

The mature fields are characterized by high water cut. One of the reasons for this phenomenon is the breakthrough of water through layers with high filtration characteristics. To solve this problem, low-volume injections of chemical reagents are used for conformance control. Effective use of this technology is impossible without preliminary calculation of the main parameters of such injection. In case of monthly update of geological and technical operations, sector models application is not realistic because of a long setup and a large amount of input data. The article considers the basis for creating an algorithm for designing wells treatment within conformance control using proxy models. The article analyzes the field experience of the use of conformance control at the fields of Rosneft Oil Company. Analysis of approximately 5000 well treatments allowed to select wells with sufficient information scope for subsequent calculations. The criteria for the effectiveness of the application of chemical enhanced oil recovery methods are proposed. The analysis shows that success rate of conformance control operations is more than 70% with average additional oil production 1600 m. A method for translating the effect of treatment in injectors to producers has been developed. The time interval during which the water cut is restored after treatment is estimated. Statistical processing of data obtained during the injection of polymer-dispersed and sediment-forming compositions is carried out. The dependence of the specific additional production (per 1 m of the injected composition) for reacting wells on the conformance control coefficient is given.

The main purpose of geologists and geophysicists work is creation of a reliable consistent geological model of a target area. At the same time, one of the main problems is the reliability of seismic predictions of reservoir parameters in complex reservoirs. The article discusses the features of predicting effective thicknesses from seismic data for the deposits of the Ju2 formation of the Tyumen suite in case of the group of fields in the Tortasinsky block. The upper part of Tyumen suite is productive almost for all deposits of Khanty-Mansiysk Autonomous District. Deposits of Ju2 strata were formed in transitional depositional environment of a coastal plain. Distinguishing features of Middle Jurassic deposits are: laterally poorly continuous shale barriers, high heterogeneity, low thickness of sandy-silty layers (close to seismic resolution), laterally abrupt sandstone facies replacement with mudstone and siltstone, presence of carbon-bearing interlayers - all of these form a complex structure of a predicted interval. Therefore, facies analysis is one of the most important tools for oil and gas reservoir study. The use of multi-scale geological and geophysical information including 3D seismic data enable interpreters to perform lateral wave pattern variation analysis and based on it identify the main facies, specified their internal structure and formation features. Based on results obtained by specialists of Tyumen Petroleum Research Center (subsidiary of Rosneft Oil Company), Sorovskneft and Rosneft it is shown that dividing of a study area into facies zones gives opportunity to improve prediction accuracy of effective thickness based on seismic attributes. The outcome of this work allow to specify hydrocarbon prospects of Ju2 strata deposits of Tyumen suite in Tortasinsky license areas of Rosneft Oil Company.

Abstract The application of chemical enhanced oil recovery methods is based mainly on data from experiments. Determining the adsorption constants without destroying the sample remains a relevant problem. It is necessary for accurate data. The determination of filtration parameters of high-molecular polymers in a porous medium using special model is considered in this paper. The aim of the investigation is the solution of inverse problem of polymer transport with adsorption. The key data for this are the characteristic times of the polymer front propagation, water and rock densities, porosity, and initial polymer concentration. The solutions of the direct problem and the inverse problem from the characteristic form of equations are obtained. The algorithm of interpretation of adsorption-retention parameters and inaccessible pore volume form non-destructive experimental studies is developed. Comparison of the calculated values of the inaccessible pore volume with the results of laboratory studies leads to an error within 10%. The practical application of the algorithm was carried out using the data obtained in previously conducted experiments.

Abstract More and more oil and gas fields are moving into the third stage of development - the stage of production decline. Oil and gas operating companies are looking for the most effective ways of production stabilization and extending the period of well exploitation. The most frequently used approach of improving exhausted reservoirs performance is reducing the pace of pressure and hydrocarbons production decline by well workovers and horizontal sidetracks drilling. The most widely used type of new producing wells trajectory in low - and medium-amplitude gas fields, which include most of the Western Siberia gas reserves, is horizontal completion. According to the analysis carried out by two major Rosneft scientific centers, in oil saturated reservoirs with thickness less than 20 meters, the efficiency of horizontal wells with 300 meters length is 1.6-4 times higher than for directional wells, depending on the reservoir thickness and permeability. In gas saturated formations, the efficiency of horizontal wells performance relative to the directionally drilled wells in similar geological conditions is 3-6 times higher. As the consequence of scientifically based well performance analysis the volume of horizontal wells drilling and horizontal side track completions at the assets of PJSC "NK "Rosneft" significanty increased as for the period from 2016 to 2021, Figure 1.

Abstract The article is devoted to determining the filtration parameters of a polymer-suspension system based on experimental data on the injection of polymer and suspension into a core sample. A dimensionless mathematical model of the filtration process based on the law of conservation of mass and Darcy's law is presented. Dimensionless characteristics of the filtration process (dimensionless effective viscosity and dimensionless parameter that determines the velocity of the polymer slug) are introduced and calculated. According to experimental data, the formation damage coefficient and the filtration coefficient during suspension injection were determined, which are in satisfactory agreement with the theories of polymer slug filtration and deep bed migration.

Kanaev, Ilya Sergeevich (Tyumen Petroleum Research Center)
Abstract Automated pay zone detection on well log data using machine learning Nowadays in the oil and gas industry more and more tasks are related to the analysis of big volume of data. Successful solutions to this type of problem are based on machine learning algorithms. The aim of this study is to create an automated model for predicting pay zones based on the analysis of well log data. The object of research are sedimentary deposits of the BV10 object of the Samotlorskoe oil and gas condensate field. In this project an approach for the gradual interpretation of lithotypes, prediction of the saturation type for potential reservoirs and also the prediction of porosity and permeability was chosen. The article discusses the application of three machine-learning algorithms: the support vector machine method, the neural network and the random forest algorithm. The existing problems of the studied data are described as well as methods for solving them and the stages of data preparation. As a result of the analysis it was decided to use a neural network to create a model for predicting pay intervals. Additionally, the accuracy of the model predictions was estimated from two wells excluded from the analysis.

Automated Identification of the Optimal Sidetrack Location by Multivariant Analysis and Numerical Modeling. A Real Case Study on a Gas Field
Magizov, Bulat (Tyumen Petroleum Research Center) | Topalova, Tatyana (Tyumen Petroleum Research Center) | Loznyuk, Oleg (Rosneft) | Simon, Evgeniy (Rosneft) | Orlov, Alexandr (Tyumen Petroleum Research Center) | Krupeev, Vsevolod (Schlumberger) | Shakhov, Dmitry (Schlumberger)
The task of choosing the sidetrack trajectory for drilling is one of the most common among specialists while workovers planning in oil and especially in gas fields. This task is solved by reservoir engineers, geologists and drilling engineers, both in a team and separately. Despite the widespread use of software for processing and analyzing the data and high automation of most routine tasks, many oil and gas companies lack a unified methodology for choosing sidetrack trajectory. Each oil and gas company has its own approach to this task. Usually, the process of analyzing candidates is based on the expert opinion of the well design engineer and has several limitations, such as: Short deadlines - on average, it takes from two to three weeks to select the sidetrack drilling trajectory. Low automation of the process of creating and analyzing the trajectory - the trajectory is created by a specialist manually, this process takes, considering the time for analysis, from two to four days for one trajectory. As a result, about five candidates are considered for the allotted time. Analysis of a small number of influencing factors -- two-dimensional maps of averaged permeability, residual reserves maps, a seismic map of average amplitudes, as well as the proximity of the candidate to the existing well stock are mainly considered during analysis of the trajectory. Prediction of the flow rates is not always based on the hydrodynamic model - when calculating the candidate's starting flow rate due to tight deadlines, not all trajectories are analyzed using the hydrodynamic model, for part of the trajectories flow rates are calculated only using analytical techniques, such as the Joshi equation (Joshi, 2018).
