ENERGY POTENTIAL OF THERMAL WATERS IN THE POLISH LOWLAND
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2010, Vol 439, Issue 439
Abstract
The paper presents results of calculations of geothermal energy resources accumulated in the aquifers of Mesozoic and Paleozoic age in the Polish Lowlands. The analysis carried out in the project covered approximately 270 th. square km, that represents more than 87 percent of the territory of Poland.The calculations were made with regard to the classification of resources, in accordance with the McKelvey’s diagram. The static, static-recoverable geothermal resources and disposable geothermal reserves were distinguished. For calculation of disposable reserves the methodology of evaluation of economic factor efficiency of heat recovery was applied (the power factor). The methodology enabled preliminary assessment of the geothermal energy utilization profitability at the regional scale and indication of prospective areas within particular aquifers. Static geothermal energy resources accumulated in nine major reservoirs: Devonian, Carboniferous, Cisuralian, Lower Triassic ,Upper Triassic, Lower Jurassic, Middle Jurassic, Upper Jurassic and Lower Cretaceousin the Polish Lowlands are estimated at 1.45 × 10[sup]22[/sup] J (3.47 × 10[sup]11[/sup] toe). Total static-recoverable resources has been assessed at 2.9 × 10[sup]21[/sup] J (6.9 × 10[sup]10[/sup] toe). Total disposable reserves of geothermalenergy accumulated accumulated in nine major geothermal reservoirs was estimated at 9.21 × 10[sup]18[/sup]J/year, which corresponds to 220 × 10[sup]6[/sup] toe/year. It should be emphasis that admissible water and energy reserves can only be assessed after drilling operation and pumping measurementshas been performed. Therefore, assessment of admissible energy resources on a regional scale is in principle not possible. Assuming the recovery of 1.5–2.5% of disposable reserves (Górecki et al., 2003), the admissible reserves of geothermal energy are estimated as 1.38–2.30 × 10[sup]17[/sup] J/year (3.3–5.5 × 10[sup]6[/sup] toe/year).
