EN The Belgian Campine Basin is part of a large paralic north-western coal basin of Carboniferous age, which also extends northwards and eastwards into the Netherlands and Germany. The Westphalian coal-bearing deposits are disconformably covered by Late Palaeozoic or Mesozoic strata and generally show a moderate dip to the north or north-east. An important transpressional fault zone of Palaeozoic age divides the basin into western and eastern sub-basins. During the Carboniferous, syntectonic differences in palaeo-subsidence caused remarkable differences in the burial history and sedimentological styles of these sub-basins and consequently, in their peat and final coal formation, its setting and CBM-potential.Large coal reserves still remain The Belgian Campine Basin is part of a large paralic north-western coal basin of Carboniferous age, which also extends northwards and eastwards into the Netherlands and Germany. The Westphalian coal-bearing deposits are disconformably covered by Late Palaeozoic or Mesozoic strata and generally show a moderate dip to the north or north-east. An important transpressional fault zone of Palaeozoic age divides the basin into western and eastern sub-basins. During the Carboniferous, syntectonic differences in palaeo-subsidence caused remarkable differences in the burial history and sedimentological styles of these sub-basins and consequently, in their peat and final coal formation, its setting and CBM-potential.Large coal reserves still remain in the Campine basin at relatively shallow depths (above 1500 m). Based on the distribution of these coal reserves and their actual rank, an overall CBM-content for the complete basin, as well as for specific anomalous zones within the basin, has been calculated by using an empirically determined (mining) rank / gas relationship. In this manner, six (6) areas have been established in which the gas concentration is significantly (5 times) above a set general threshold value. Together they represent a significant, minimal producible (E)nhanced CBM "target-volume" of about 53 x 109 m3 of methane. The various target areas demand different approaches in any (E)CBM development. In the southern parts of both sub-basins, the remaining changes in porosity/permeability and stress conditions of the rocks, caused by the former mining activities, have to be included into the (E)CBM-development schemes. More towards the north and north-east, any use of preserved coal mining influences is simply not possible. Here, both the sedimentological and structural setting of coals will determine the predominant geologic (E)CBM-development factors.Possibilities for ECBM-production by CO2, N2 or even "raw" flue gases are largely present within or very close to the most prolific CBM-areas. Gas-pipelines and other infrastructure needed for (E)CBM-development are present in the basin, too. The basin is situated within a low to moderately populated part of the country, which is actually rapidly economically expanding. This certifies a steadily increasing gas-consumer market in the next decades.
