Hydrocarbon Field

A hydrocarbon field is a large and complex system, which functioning is possible only in accordance with a project document that defines the main characteristics for the entire period of field development. Therefore, the quality of the project document largely determines the efficiency of the field system functioning. The last stage in creating a project document for the development of a field is an economic assessment. According to the experience of designing the development of hydrocarbon fields, up to 50% of capital investments are the costs of drilling new wells of various types. Thus, the economic efficiency of field development is largely determined by the volume of drilling new wells. The article presents an integrated approach to modeling the development of hydrocarbon deposits in making a production forecast. Such an integrated approach involves performing a rapid economic assessment using Economics software which allows you to calculate the main economic indicators of field development. Thus, it reduces the total number of iterations for setting the forecast for field development strategy by an average of 25% as well as improves the economic characteristics of the whole project.

The analysis is carried out and the problems of the current state of mining in the coal mines of the Russian Donbass are identified. To increase the efficiency of their work, it is proposed to create a mathematical model that allows tracing the probable zones of tectonic disturbance. We apply this technique for the southeastern wing of the inclined part of the mine field of the Sadkinskaya mine. On the basis of the constructed forecast map of coal seam disturbance, we solve the problem of choosing the optimal cutting of a section of a mine field. To do this, we make a technical and economic assessment taking into account such factors as: losses and quality of mined coal, production capacity of the mine and time for preparation and development, volume of capital investments, cost, taking into account costs when crossing disturbed zones.

Hydrocarbon Field

Modeling in the process of oil production has been used almost since the beginning of hydrocarbon field development, when there were ideas about the conditions of formation occurrence and oil flow to wells. An empirical model is proposed to calculate the current production rate of wells in the hydrocarbon field by year. Based on this model, an equation for calculating cumulative production was constructed. The proposed model is compared with known models and actual development history data. The resulting models of current production rates, cumulative production and recoverable reserves most accurately describe the actual results and have a high correlation parameter compared to other models.

Abstract Considering the imminent end of the ‘easy oil’ era, the increasing demand for energy and the global push towards the energy transition, oil and gas companies are more than ever interested in sustainable ways to develop marginal and complex hydrocarbon fields economically, through the application of technology and maximization of data analysis. In small partially appraised fields where the cost of drilling an appraisal well could derail the project economics, it becomes necessary to sweat the limited data available for reservoir modelling. The uncertainty analysis must be robust enough to ensure that the adopted field development strategy would yield a positive net present value despite the wide uncertainties associated with the field. The conventional workflow for subsurface uncertainty modelling involves defining the uncertainty ranges of static and dynamic reservoir parameters based on a single reservoir model concept. This paper focuses on a marginal field case study where the multi scenario modelling approach was adopted. This approach considered alternate reservoir geologic concepts based on different interpretations of the reservoir architecture, taking full cognizance of the available data, reservoir uncertainties and regional geology knowledge. Field Alpha is located onshore of Niger Delta in Nigeria. The geologic setting consists mainly of multi-storey, complex channel-belt systems, incising through Shoreface deposits. The reservoir of interest is an elongated structure with only two well penetrations located at the opposite distal part of the structure. The key reservoir uncertainties are reservoir structure, architecture, connectivity, and property distribution. Two possible distinct architecture were interpreted based on regional correlation and seismic. This paper focuses on how the interpretations and other information informed a robust development strategy that yielded significant (30 %) reduction in development cost and positive net present value.

This study accommodates subsurface uncertainties analysis and quantifies the effects on surface production volume to propose the optimal future field development. The problem of well productivity is sometimes only viewed from the surface components themselves, where in fact the subsurface component often has a significant effect on these production figures. In order to track the relationship between surface and subsurface, a model that integrates both must be created. The methods covered integrated asset modeling, probability forecasting, uncertainty quantification, sensitivity analysis, and optimization forecast. Subsurface uncertainties examined were : reservoir closure, regional segmentation, fluid contact, and SCAL properties. As the Integrated Asset Modeling is successfully conducted and a matched model is obtained for the gas-producing carbonate reservoir, highlights of the method are the following: 1) Up to ± 75% uncertainty range of reservoir parameters yields various production forecasting scenario using BHP control with the best case obtained is 335 BSCF of gas production and 254.4 MSTB of oil production, 2) SCAL properties and pseudo-faults are the most sensitive subsurface uncertainty that gives major impact to the production scheme, 3) EOS modeling and rock compressibility modeling must be evaluated seriously as those contribute significantly to condensate production and the field’s revenue, and 4) a proposed optimum production scenario for future development of the field with 151.6 BSCF gas and 414.4 MSTB oil that yields a total NPV of 218.7 MMUSD. The approach and methods implemented has been proven to result in more accurate production forecast and reduce the project cost as the effect of uncertainty reduction.

Management Concept

There are few activities so susceptible to the impacts of the macro environment as tourism. In conditions of growing uncertainty, the importance of strategic management is steadily increasing. By studying the environment, by anticipating the future development and implication of trends on enterprises, and by developing appropriate strategies at a number of levels, strategic management seeks to actively influence the increase o f competitive advantages o f both the tourist destinations and tourist enterprises. The term “strategic management” implies a set of management decisions and actions that determine the long-term operations o f enterprises within the management system of tourism: guiding the enterprise by anticipating crucial environmental impacts and internal factors. This management concept is based on the assumption that making properly oriented strategic decisions minimizes the negative effects of the environment and creates strategic advantages for enterprises that can be capitalised only in the medium and long term (Čizmar S. (2001) Strateško upravljanje u funkciji učinkovitog razvoja turističkog ugostiteljstva u Hrvatskoj, doctoral dissertation, University o f Zagreb, Faculty of Economics, Zagreb, p. 3). It represents an integrated approach to strategic management that is the most acceptable for the development of Croatian tourism, as long-term positive results, in both market and financial terms, can be achieved by enterprises within the tourism management system of Croatia only by applying an integrated approach to strategic management, by horizontally and vertically linking the elements of all subsystems of the entire management system and by creating partnering relationships. The Croatian model of strategic management should involve the economic optimisation of all subsystems and systems by establishing efficiency not only across all subsystem elements, but through the system as a whole as well. The level of growth in entrepreneurship and innovations will determine the intensity and speed of positive development changes. These changes will also depend on establishing management responsibilities throughout all segments and managements levels of all subsystems, as well as tourism as an integral system. This paper deals with the issues of strategic management at a micro level with special emphasis on the development of responsibility for managing performance and capital investments.

Hydrocarbon Deposits

Nadym-Pursk oil and gas region has been one of the main areas for the production of hydrocarbon raw materials since the sixties of the last century. A significant part of hydrocarbon deposits is at the final stage of field development. An increase in gas and oil production is possible subject to the discovery of new fields. The search for new hydrocarbon deposits must be carried out taking into account an integrated research approach, primarily the interpretation of seismic exploration, the creation of geological models of sedimentary basins, the study of geodynamic processes and thermobaric parameters. Statistical analysis of geological parameters of oil and gas bearing complexes revealed that the most promising direction of search are active zones — blocks with the maximum sedimentary section and accumulation rate. In these zones abnormal reservoir pressures and high reservoir temperatures are recorded. The Cretaceous oil and gas megacomplex is one of the main prospecting targets. New discovery of hydrocarbon deposits are associated with both additional exploration of old fields and the search for new prospects on the shelf of the north. An important area of geological exploration is the productive layer of the Lower-Berezovskaya subformation, in which gas deposits were discovered in unconventional reservoirs.

The predominant area of application of the developed methodology is the construction of the distribution of the geodynamic state of the developed hydrocarbon fields in oil and gas basin, and the identification of the corresponding distribution law. A number of the hydrocarbon deposits in terms of geological conditions of occurrence, structure and other parameters are geodynamically hazardous during their development. The Federal Law «On Subsurface Resources» (Article 24) requires conducting a complex of geological, surveying, and other observations sufficient for ensuring a normal technological cycle of work, and the prediction of hazardous situations. The developed methodology based on the construction of aggregated additive models for each reservoir and field is presented. It includes four sequential stages (24 operations): first — prepare geodynamic data; second — determine the geodynamic state of productive strata; third — find the geodynamic state of the developed deposits subsoil; fourth — build the distribution of the bowels geodynamic state of these fields for the entire oil and gas basin and identify the relevant distribution law. Oil and gas basin in the west of the Orenburg Region (Volga — Ural and Caspian oil and gas provinces) is considered as an example of implementation. Unique data of twenty geodynamic parameters of 320 productive strata (56 fields) were used. It is revealed that in accordance with the Pearson criterion, the theoretical data with a high confidence probability (95 %) correspond to the law of normal distribution. Developed methodology has significant technical and economic advantages, since it allows to identify the geodynamic state of productive strata and subsoil of the fields being developed, to identify hazardous geodynamic processes and to choose rational modes for the development of hydrocarbon deposits.
