Abstract
Field Cluster E has a number of producing and non-producing fields. While drilling exploration and development wells in this block, there exists numerous wellbore instability issues. Major wellbore instability issues include total and partial losses in shallower overburden, shale instability in intermediate section, and depleted reservoirs in development wells. These wellbore instability issues lead to drilling operations related non-productive time (NPT). In order to minimize NPT related to wellbore instability issues, Geomechanical study is initiated. This paper discusses the role of Geomechanical modeling for successful well delivery in ongoing exploration and development targets.
Understanding the state of stress and rock strength is very important for wellbore stability design. Comprehensive drilling analysis is carried out for number of offset wells to identify the drilling hazards. 1D Geomechanical models are built by integrating the data from drilling, geology, geophysics, petrophysics and reservoir engineering disciplines. Vertical stress is estimated by integration of density log from surface to reservoir TD. Pore pressure is constrained using Normal Compaction Trend (NCT) techniques, calibrated by formation pressure measurements. Formation Integrity Tests (FITs) are acquired and doesn't give any idea about minimum horizontal stress. In the absence of LOTs & rock mechanics tests, regional Oman experience is utilized. Orientation of maximum horizontal stress is determined using Caliper, Image logs and World Stress Map. Magnitude of Maximum horizontal stress is constrained using Stress Polygon Methodology. Knowing the magnitude and orientation of in-situ stresses, pore pressure and rock strength can help in evaluation of wellbore stability. 1D Geomechanical models are then calibrated against actual failure observed in Caliper log and wellbore instability events.
These calibrated 1D geomechanical models are then utilized for predicting mud weight in upcoming exploration and development wells. Wellbore stability analysis has helped to predict optimum mud weight for a number of exploration and development wells. Detailed drilling hazard analysis and Geomechanical Modeling also helped to design optimum mud type for solving wellbore instability issues using specialized mud additives.
Design and implementation of optimum mud weight and mud type using integrated geomechanical modeling and drilling fluid design has helped to drill number of vertical and highly-deviated wells with reduced NPT. The study has also helped to reduce or remove associated drilling hazards and facilitated successful well delivery by proactively working together between sub-surface and drilling engineering teams. This paper discusses the implementation of study results to one planned well in detail.

Abstract
This paper investigates the CO2-assisted viscosity reducer composite flooding technology for addressing issues such as low recovery and high residual oil saturation in conventional heavy oil reservoirs. A three-dimensional numerical simulation model was established to systematically analyze the influence of key parameters such as reservoir sealing and crude oil viscosity on development effectiveness, leading to the establishment of an applicability evaluation system for CO2-assisted cold production of heavy oil reservoirs. The displacement mechanism of CO2-viscosity reducer composite flooding was studied through microscopic visualization experiments, examining the effects of different injection methods and timing. Field tests were conducted to verify the feasibility of this technology. The results show that: (1) reservoir sealing, oil viscosity, permeability, and cycle period are the main factors affecting development effectiveness; (2) the anionic-nonionic composite viscosity reducer exhibits optimal viscosity reduction and oil displacement performance; (3) mixed injection method achieves the best microscopic displacement effect; (4) the daily oil production of field test well increased from 0.7t to 2.2t, validating the production enhancement effect. This study provides theoretical basis for the promotion and application of CO2-assisted cold production technology in heavy oil reservoirs.

Executive Summary
Rock thin section analysis and interpretation are important processes in understanding formations. This study shows a new quantitative system to automatically search through thousands of legacy thin section images and their associated metadata and interpretation to find the closest match to an unlabeled sample. The system utilizes image-processing and neural-network-based encodings to build a database. Using this, it is possible to utilize existing legacy data as a guide to interpret new samples. The advantage of the system is that the associated metadata for the legacy thin sections does not need to be structured and images do not need to be labeled. Thus, we maximize the utilization of existing data without the need for these time-consuming tasks that are usually needed for most formulations of machine learning problems.

Abstract
Dai Hung Nam (DHN) discovery consists of four sub-blocks separated by highly faulted structures, of which three wells were penetrated in different sub-blocks with two successes. However, the failure of the third well at the SB-3 sub-block induced a change to marginal development and made it difficult to decide whether to drill the fourth to continue the appraisal process or terminate the project to minimize the investment. The failure is caused directly by aspects of thin, tight, and low-permeability reservoir's properties; however, indirect reasons might be in terms of volumetric, shaped, and positional accuracy of the drilling targets that being affected by velocity modeling resolution and fidelity as well as fault imaging quality of the legacy processing dataset.
To overcome the challenge, we launched the updated seismic reprocessing which focuses on both depth imaging with high-resolution and accurate model building and improving image quality with free-noise and high-resolution of the faulted systems. In addition, we also take care of the presence of complex overburden such as volcanic local features, which introduces another modeling challenge at the deeper reservoir targets.
This report is to share an experience in getting a high-resolution and accurate velocity model by layer-striping tomographic scheme over ultra-faulted geological structures. With the precise model and adequate signal processing, the anisotropic Kirchhoff pre-stack algorithm was well-imaged to improve the accuracy and reliability of the seismic reflector, fault definition, and data bandwidth. The new interpretation on the re-processed data illustrates that the hydrocarbon volume in the sub-blocks SB-1 and SB-2 had increased by 18% and 13%, respectively. Consequently, resources in the last un-drilled sub-block SB-4 increased by about 44% if put in comparison with the legacy estimates. This evidence has fully supported the decision to drill the final appraisal well with a successful drill stem test (DST) of maximum flow rate of 6,900 barrels oil per day (bblopd). This result converts the project from a marginal discovery to a development stage, and the seismic dataset will continue to support the well-design and optimized drilling locations in the development phase as well as further quantitative interpretation (QI) studies such as AVO and inversion.

Introduction. The transition to the managerial rationalism at the present stage of western management development is expressed in the conviction that the commercial success of an enterprise is mainly determined with the rational organization and management system of products manufacturing, general reduction in expenses on the manufacture and sale of the production, development of more focused specialization. The current strategy of western management is largely supposed to have the influence on the factors of internal environment of an enterprise through the management (the manufacturing process is included). The opportunity for adaptation of foreign company based on the experience of its activity in the Orenburg region are considered in the paper. It is about the American company John Deere or, more truly, about a regional representative of the abovementioned company in the Orenburg region ООО John Deere Rus. Both the traditional and innovative methods were used in the research. PEST-analysis, SWOT-analysis, Porters structure, which includes the study on five competitive forces, are the traditional tools for the study of the external environment. The analysis of the external environment revealed that the demand for John Deere products was rather stable. For 12 years of John Deere activity in Russia, the company found a good number of regular customers, who ensured the enterprise with work and profit, necessary the company to exist. The authors consider the John Deere company should keep the concentrated growth when strengthening weak, domestic positions. According to the economic essence of adaptation, they offer to implement in the system of management of the company the Department of Analytics by introducing the amendments to the existing organisational set-up of ООО John Deere Rus. The Department of Analytics at ООО John Deere Rus will contribute to adaptation to the environment changes. More effective, managerial decisions shall be given on the basis of the obtained information and conducted analysis as well as data comparison provided by the Department of Analytics. Conclusion. Understanding of the importance of outside environment assessment when managing the activity of an enterprise and connection of managerial influence with the dynamics of factors of environment is an important factor under the adaptive management of an enterprise. To support the capacity of an enterprise at an adequate level, to achieve its goals and to survive in a long-term perspective, there is a need in a continuous adaptation to the changes of market environment factors.

В 90-е годы двадцатого столетия личные подсобные хозяйства для многих семей были основным источником поступления денежных средств и фактором самообеспечения продовольствием. В последние годы отмечается снижение интереса населения к производству продукции сельского хозяйства на своих приусадебных участках. Итоги Всероссийской сельскохозяйственной переписи 2016 года свидетельствуют о значительном уменьшении в хозяйствах населения как посевных площадей, так и численности поголовья сельскохозяйственных животных. Это обусловливает снижение вклада населения в продовольственное обеспечение страны и самообеспечения домашних хозяйств продуктами питания.
Introduction. The private farms of the villagers make a significant contribution to the production of agricultural products and food self-sufficiency of the country. However, the number of private farms engaged in agricultural production is decreasing. This causes a decrease in production volumes. The goal of the research is to justify the need for state support of citizens living in rural settlements and keeping personal subsidiary farms, upon condition of their work in agricultural production. Currently, the national agri-food policy is aimed at achieving food independence of the country by increasing the production of agricultural products by large integrated associations. However, this is not enough to achieve the food security of an individual citizen of the country. In conditions of low incomes of the population, economic availability of food is not ensured. At the same time, the population, including the rural population, reduces agricultural production in their backyards as income from other types of activity increases. This is due to various factors the main, of them is that production is based on the use of heavy manual labour of family members. It should be noted that the population reduces production not only for sale, but also for personal consumption. This, in turn, leads to a decrease in the quality of nutrition. According to statistics, the quality of nutrition of villagers is lower than that of the townspeople. Malnutrition has a negative impact on public health and life expectancy. In conditions of low wages in agriculture, personal subsidiary farms is an additional source of cash and food for the workers in the industry. The statistics data indicate a relationship between the provision of farms with agricultural animals and the level of consumption of food of animal origin. Conclusion. In order to stimulate an increase in the production of agricultural products, state support is needed for the owners of personal subsidiary farms in rural settlements. Labour in private farming in the agrarian sector of the economy should be recognized as an additional employment. This would enable to have the preferential conditions for retirement.

В статье обосновывается возможность стандартизации анализа хозяйственной деятельности (комплексного экономического анализа хозяйственной деятельности) по методологии, сложившейся на основе многолетнего опыта преподавания дисциплины в вузах и использования анализа в хозяйственной практике.
Introduction. Standardization plays a significant role in the development of various areas of economic activity. A lot of national and international standards have been developed in order to manage quality, projects, risks, personnel, etc. However, economic analysis has not yet been standardized, which leads to a number of limitations in conducting analysis. This is expressed in different interpretations of the names of some economic activity indicators at enterprises, payment and evaluation methods. This hinders the economic analysis from becoming an effective management function, which reduces the degree of validity of managerial decisions. The purpose of this work is to substantiate the possibility of developing analytical standards based on the existing methodology of economic analysis. By now, there are a lot of information sources necessary for standardization of economic analysis including regulatory documents; publications; educational and methodological materials on economic analysis. In recent years, the valuable contributions by Melnik M. V., Gerasimova E. B., Barilenko V. I. and other researchers have made significant progress in addressing the issues of economic analysis standardization. The author has provided grounds of the principles of construction and requirements for the analysis standard and structure. The paper emphasizes the fact that "Economic analysis" course structure has remained unchanged for several years, therefore, it is possible to consider the objects of economic analysis unified, and the tasks – typified. The release of the standard "Analysis of Economic Activity" is bound to result in numerous positive consequences. First, the standard should be approved by the government, therefore, the government institution will be involved in economic activity analysis. In order to approve the Analytical Standard, field specific Analytical Standards, corporate standards are going to be developed. In this case, the economic analysis is going to become a full-fledged managerial function, which is particularly important for the modern period of structural transformations in economy. Secondly, the standard can serve as a basis for the development of research into economic analysis. In the third place, there will be a unified approach to teaching the discipline "analysis of economic activity", strengthening students ' skills for analytical research through the development of requirements for analysis. Conclusion. Standardization of the regulations for conducting economic analysis is going to harmonize the system of standards and systematize its management based on the interrelation between accounting, control and analytical support for managerial decision-making.
