Analysis of the exploitation of existing deep production wells for acquiring geothermal energy

The aim of the work is to assess the possibility and usefulness of acquiring geothermal energy from the existing production well Jachówka K-2. The initial assumptions that are essential for estimation of both a heat flux transferred between a deposit and a heat carrier and a heat flux permeated through the barrier are discussed. To achieve this goal, the authors have worked out a computational model that allowed them to determine the value of the gained geothermal heat flux using a double-pipe geothermal heat exchanger with a dead center. In what follows, the results of calculations of a heat flux that can be gained in the investigated well at a depth L = 2870 m are given.__________Published in Inzhenerno-Fizicheskii Zhurnal, Vol. 78, No. 1, pp. 123–130, January–February, 2005.
