Opis:: The Polish Geological Institute (PIG),established in 1919 as the geological survey, during the last 100 years carried out geological prospection of Poland, worked out the actual knowledge of geology and hydrogeology of the country, as well as discovered most of mineral deposits, essential to the national economy. This synthetic review presents the PIG achievements in prospecting and documenting of most deposits of rock and potash salts as well as in successful creation and application of new methodology and technics (e.g. chemostratigraphy, resource aspects of facies analysis, 3D images of salt deposits and structures, interferometry) to predict salt occurrences with optimal resource parameters, explain the tectonic and stratigraphic problems and to propose tools favoring the mining safety. The data regarding regional geology, collected during a century, enabled estimation of accessible prospective resources of both salt types and selection of optimal salt occurrences forfuture management as storages for hydrocarbons, gas (air, hydrogen) and safe waste disposals.

Opis:: Gas in shales occurs as a constituent of rock and its resources can be estimated in a similar way as the metal content in ore deposit. The cutoff gas content in rock is the basic parameter defining deposit boundaries. It is proposed that the cutoffs in gas-bearing rocks are 2 m3 gas/t and 15-m deposit thickness. In case of lack of sufficient data, the deposit boundaries for resources estimation may be delineated in a defined distance from prospecting boreholes, supported by geophysical data, if possible. Discovered gas resources may be evaluated by volumetric methods. For reserve estimation, dynamic methods should be applied based on shale fracturing results. Following the stages of prospecting and exploration, decreasing uncertainty of the deposit resources/reserves evaluation may be expressed by D, C, B and A categories, or with the use of PRMS classification system.

Tytuł:: Kopalnia rud cynku i ołowiu Pomorzany skończyła 40 lat : jak długo jeszcze wystarczy jej zasobów?

Opis:: The Pomorzany mine, currently the only one Zn-Pb mine in Poland and one of the largest underground mines of this type worldwide (output 2.5 Mt/y) exceeded 40 years of operation on the MV-type deposit. In 1960, the first geological report on its resources based on drillings was issued. Data from this long period were used to analyse the resource management and evolution of reserve tonnage and quality due to changes in the economic and technical viability as well as to qualify different categories of mine reserves and losses due to the ongoing operation. The mine project was based on geological resource of 97.6 Mt ore averaging 4.12% Zn and 1.42% Pb. Resources extracted with documented low losses and those remaining in situ amount to 92.7 Mt averaging 4.18% Zn and 1.27% Pb. These figures indicate the high accuracy of the exploration results and cost-effective management of resources. The observed trend of ore reserve increase over the last decade gives hope of delimiting at least 3 Mt over the next three years. The mine, which was planned for a 30-year life cycle, has sufficient reserves until 2016, and under favourable market conditions, may extend its life up to 2018.

Opis:: Gas produced from coal can be subdivided into three categories: coalbed methane (CBM), coal mine methane (CMM) and abandoned mine methane (AMM). CBM is extracted from virgin coal using wells drilled from the surface. In recent years horizontal drilling is widely used as a primary CBM recovery technique. A pair of wells - a vertical production well intersected by a horizontal multilateral well - is considered the most effective in dewatering a coal reservoir and thus enables maximizing its productivity. Although CBM world resources are huge (100-216 bcm), only a few countries produce coalbed gas commercially. While the US is still the leader, Australia has the fastest CBM production growth. It has been observed that many mature CBM plays reveal highly variable productivity, possibly due to coal heterogeneity. Therefore, CBM reserves/resources should be estimated using probabilistic methods. In spite of its substantial CBM resource potential, Poland has produced only coal mine methane (CMM) whereas significant efforts of CBM exploration conducted in the 1990s failed to flow gas in commercial quantities due to low permeability. Dart Energy operates a CBM exploration license in the Upper Silesia and has recently finished testing the CBM production pilot using a surface-to-inseam horizontal well with vertical production well intersection. This state-of-the-art CBM completion technology has been used for the first time in Poland and, hopefully, will unlock the sizeable CBM resource of the Upper Silesian Coal Basin.
