Abstract: The Hungarian Office for Mining and Geology (hereinafter MBFH) and the Geological and Geophysical Institute of Hungary (hereinafter MFGI) are working in co-operation on a project (hereinafter ”project”) which aims to achieve the joint modernization of the national mineral resources inventory and classification. This research project has been commissioned by the MBFH and also involves the Hungarian Geological Society. The implementation of the modernization involves careful examination of the content requirements of the exploration reports on the mineral resources. During the research the project members analysed the mineral resources classification systems applied in practice, as well as the reporting standards and codes based on the classification. The most important ones will be briefly presented in this article and the subsequent papers.
This paper focuses on the classification systems applied for solid minerals, with the latest version of the United Nations Framework Classification (UNFC), the CRIRSCO Template and the USGS system being given special attention. The harmonization possibilities of different classifications are also introduced.
It is a considerable challenge for the institutions and organizations involved in the project to discuss the applied definitions and methods then come to an agreement about the common ground on a theoretical level and then practical application. One of the certain results of the project will be the requirement for operators to provide data in line with the international codes. These data should meet all the standard formal and content stipulations. Furthermore, the State Inventory of Minerals and Geothermal Energy maintained by the MBFH should have the capacity to manage this information. The harmonization of data and their efficient management represent a connection between these factors and this is of fundamental importance in achieving modern mineral resource management.

Abstract: In the present paper an overview is provided of the most important international classification systems of geothermal energy. This involves a demonstration of the applicability of the UNFC-2009 classification framework to renewable energy resources, especially with respect to geothermal energy. Here an attempt is also made to classify some typical Hungarian geothermal projects which are in accord with the UNFC-2009 scheme, and then to illustrate this harmonization with a Monte-Carlo based resource estimation for the Hódmezővásárhely geothermal district heating project.

Abstract: In the framework of cooperation taking place between the Hungarian Office for Mining and Geology (MBFH) and the Geological and Geophysical Institute of Hungary (MFGI), the project “Overview of international systems of mineral resources inventories — the base for national harmonization” was launched in 2013. One of the sub-tasks of the project is the modernization of the inventory for hydrocarbon mineral resources. In the course of the work a study has been carried out which comparing and contrasting the domestic recording system with the various international reporting standards (including the UN framework for classification). The present paper demonstrates how the domestic inventory can be integrated with international systems. The suggestions made are backed up with a case study.
In developing the hydrocarbons topic which is integral to the project the MBFH and MFGI staff — together with the experts of the Hungarian Geological Society and the entrepreneurial sphere representing the Hungarian Mining Association — reviewed: (i) the current structure of the domestic hydrocarbon inventory, (ii) final reports and reporting practices of hydrocarbon prospecting and research published in annual reports, (iii) the expectations of the MBFH with regard to the reporting of production by companies,(iv) the applicability of international classifications in Hungary and (v) the possibilities for developing and adjusting the current hydrocarbon resource inventory used in Hungary.
A working consensus has emerged that data concerning the discovered hydrocarbon resources and published in the final report of the research, can be classified by the Petroleum Resorces Management System (PRMS) of the Society of Petroleum Engineers (SPE). However, for the aforesaid to be valid it is neessary that the data can be correlated with the coding in the United Nations Framework Classification (UNFC). A “Glossary” was made by the experts and this includes detailed definitions of the SPE/PRMS system. Furthermore, a proposal has been put forward which aims to modernize “Block data profile” used for the hydrocarbon inventory data report of entrepreneurs. It also intends to ensure compliance with the proposed classification systems. The results may help the MBFH in its efforts to implement the standardized treatment and processing of data — i.e. that received from entrepreneurs — by using state-of-the-art methods.

Abstract: The preparation of the modernization of the non-metallic mineral resource inventory (and its concomitant re - commendations) were parts of a particular task related to a project which has been operating since 2013. This project represents a process of co-operation between the Hungarian Office for Mining and Geology and the Geological and Geophysical Institute of Hungary. In conjunction with the work on the national inventory, different international re - porting standards — including the UNECE classification framework (UNFC-2009, UNECE 2013) — were also studied. This paper presents suggestions on how the national inventory of Hungary could be harmonized with an international classification framework for reporting standards on mineral resources. A case study is also considered.

Abstract: This paper presents details about the development of the domestic registry of coal resources, as performed in recent years. The contents of the paper are the product of co-operation between the Hungarian Office for Mining and Geology and the Geological and Geophysical Institute of Hungary. The most important results are (1) a thematic map series of the Hungarian coal basins containing 19 parameter maps of a scale suitable for reviewing (2) GIS representation on the volume calculation blocks of selected explored sites; these sites are regarded as suitable for a proclaiming tender.
According to comparisons with international classification systems, the Hungarian registry of coal resources is in line with the generally accepted geological (UNFC G axis) and feasibility (UNFC F axis) indicators. However, due to the lack of per-unit costs the economic efficiency (UNFC E axis) cannot be determined with certainty. This is a considerable deficiency from the aspect of strategic (e.g. regional development) decisions related to domestic coal resources in Hungary.
In order to determine rentability, up-to-date mining plans presenting investment and operating costs — together with information on the coal market — are indispensable. The staff of the Geological and Geophysical Institute of Hungary intends to contribute to the filling of the gaps in both fields. With respect to up-to-date mining plans, model plans and associated studies can be carried out. In the case of market conditions, geochemical parameters require investigation; these are essential for the interpretation of aspects of the types of coal in Hungary from a chemical industrial (gasification) point of view.

Abstract: The need to assess the potential of CO2 storage complexes and their related respective storage capacities is quite a new area of study. Carbon capture and geological storage (CCS) has only recently been recognized as an efficient means of mitigating climate change. In Europe, with the exception of Norway, the significance of CCS activity only reached that critical level involving the demand for a standardized registry after 2007; furthermore, this task has been confronted by the institutions responsible for resource management. Since 2007, the capture and geological storage activity of carbon from industrial sources has developed dynamically on a worldwide scale. However, over the last 4–5 years Europe — which at one time led research in this field — has experienced a strong fallback in the spreading of CCS technologies. This is mostly related to economic problems in Europe and low carbon prices. Nevertheless, the rest of the World — e.g. the United States, Australia and China — has made notable technological progress with CCS. It is this uneven development of CCS that has led to significantly louder demand for a standardized registry indicating the potential storage on a global scale.
The demand has also motivated several organizations operating on an international; level to develop registry systems for potential storage sites. These registry systems are quite similar to those which have been used for hydrocarbons for several decades now; this is due to the fact that most of the applied technology — as well as the potential storage sites themselves — are similar. However, there are still some specific characteristics of carbon storage that trammel the general use of some of the definitions applied to hydrocarbons. This paper deals with the presentation of some of the registry systems developed for carbon geological storage over recent decades. The present study focuses mainly on the most complex system proposed by the SPE (Society of Petroleum Engineers). The last part of the paper attempts to classify potential storage sites in Hungary, in line with the SPE system. (It should be noted that the United Nations Framework Classification — UNFC — has produced Draft Specifications for the Application of UNFC-2009 to Injection Projects for the Purpose of Geological Storage. However, owing to the fact that the content of this classification has not yet been finalized, it is not dealt with here.)
