This study aims to assess the potential of EU's resources of coal (lignite and hard coal) as well as coal bed methane (CBM) and to obtain a digital European database covering all coal basins within the EU. This requires:
— an evaluation of the existing sources and classifications of data relating to coal deposits including potential sources of CBM in the EU based on data residing in national geological surveys, data which industry partners are willing to share and other published data,
— the formulation of a common classification and terminology for coal typology and for CBM reservoirs for Europe taking into consideration existing methodologies and classifications (relation to main national systems in the EU as well as to classifications used by international organisations need to be documented),
— the creation of a geographical database of the coal deposits in the EU differentiated by coal type on the basis of the proposed common classification with further differentiation and details, where feasible. The data should allow for ease of comparison and be broken down by coal basin and by country. It should include information which areas are being actively mined, which are in the closure process and which are already planned mining areas for the future. Main information like the depth and the calorific content of deposits should be indicated. Furthermore, estimates for the gas reservoir of the coal deposits should be given by using the existing data and information from coaliferous basins including active and abandoned mines. The data on CBM should be included in the geographical database and should comprise parameter classes like gas content, permeability, natural fracturing, pressure and further characteristic reservoir properties. In the case of insufficient data, estimates should be given, based on the available data and level of geological knowledge,
— production of a map of the EU coal basins, together with smaller subsectional maps which visually display the EU coal deposits including their estimated CBM potential differentiated in a clear manner by coal type and classes and gas reservoirs as well as other layers of data,
— the geographical database should allow displaying data in a variety of formats, including maps (isopach, colour, parameters), data points, data tables, cross sections. It should contain the geo-referenced data which were used to draw the maps including coal-related data and comments. The tenderer will provide the Commission with a description of all deliverables. The geographical database must have precision equivalent to the scale of 1: 500 000 or larger. The data should relate to a time period spanning not more than 1 year. Metadata describing the database will be part of the offer (see I.2.C 'Metadata and documentation requirements').
