Развитие методики 3D-сейсморазведки в арктическом регионе

This article discusses the technological aspects of developing a methodology for detailed seismic surveying using the 3D method in the Russian Arctic. The primary aim is to enhance the economic efficiency of the exploration stage in oil and gas field development. The paper highlights the significance and substantiates the advantages of 3D seismic surveys that make it possible to drill production wells without the need for exploratory drilling. It is established that the principal impediment to technological advancements in seismic surveying within Arctic regions is the restrictive policies of Western nations, which primarily take the form of sanctions. Factors influencing the economic efficiency of seismic surveying include the quality of fieldwork management and workers' professional skills, both of which can catalyze the evolution of seismic survey techniques. The article presents an illustrative case of detailed seismic surveys conducted on the Gyda Peninsula. An innovative seismic survey technique is introduced, and an integrated indicator, which is grounded in criteria reflecting the quality of work, is proposed and employed for an objective assessment of economic efficiency. The proposed methodology has been successfully tested, proving its advantages, and the results obtained are of value for the sector of seismic surveying. It is proposed that the methodology should be used by geophysical companies deploying high-density seismic survey methods to find new hydrocarbon fields in northern territories.

DEVELOPMENT OF RISK ASSESSMENT METHODS IN THE IMPLEMENTATION OF EXPLORATION PROJECTS

The peculiarity of oil and gas projects is their long implementation period, during which they are subject to the influence of a large number of different risk factors that complicate project implementation and result in failure to achieve the planned economic indicators set by investors. The effective operation of companies therefore depends on how reliably investors can predict the prospects for project development. The success of the subsequent functioning of the investment project depends to a large extent on the reliability of the assessment of the effectiveness of the investment project, based on the optimally chosen strategy of its development, and, above all, on the anticipation of possible risk factors and tools for their prevention. Therefore, at present, the competitive struggle in the oil and gas production industry is currently shifting to the area of pre-project preparation of investment projects and increasing the reliability (quality) of their economic efficiency assessment at the stage of making a decision to start their implementation.Geological risks become important in the implementation of exploration projects, the first stage in the overall process of developing the Company's assets. It is necessary to find a balance between the cost of project implementation and the amount of accumulated hydrocarbons for the forecast period, which will ensure maximum profitability of the project. The challenge to optimize the financial outlay on the implementation of geological exploration works by focusing on the most promising and important projects for companies becomes relevant. In this regard, the article considers the methodological approaches proposed by the author to assess the risks of exploration with the aim of improving the efficiency of the planning process and reducing inefficient financial costs.

Analysing renewable energy flow distribution and its influence on grid electricity prices

The paper presents an approach to the assessment of technical and economic efficiency for an electric energy (EE) transport in a distribution grid. It is focused on the extent of renewable energy sources (RES) integration efficiency according to energy prices in a grid. A two-step procedure for calculation is used in terms of the approach. The first one includes the obtaining of energy flows distribution in a grid. The next step provides the calculation of costs flows and nodal prices for electric energy. Both stages are performed using a developed branch flow model. Unlike power flow distribution describing the instant point of time, energy flow distribution developed for any operation duration deals with the integral values of the flows. This is of great importance for the deeply varying output profiles of the intermittent renewables. The model provides the direct utilization of electric energy meters data available in a grid. The approach presented is essential for locating the particular consumers of the renewable energy in terms of a grid’s deep state and circuit diversity as well as for analyzing the influence of a renewable energy for electricity prices, and estimating the necessary renewables’ levelised cost of energy (LCOE).
