The aim of the work is to assess the possibility and usefulness 
of acquiring geothermal energy from the existing production well Jachowka 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.
