THE ANALYSIS OF EXPLOITATION OF EXISTING DEEP PRODUCTION 
WELLS FOR WINNING THE GEOTHERMAL ENERGY

The aim of the work is to assess possibility and usefulness 
of winning the geothermal energy from the existing production well 
Jachowka K-2. The initial assumptions 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 gain the goal, the authors have worked out a computational model 
which allowed them to determine the value of a gained geothermal heat 
flux using a double-pipe geothermal heat exchanger with the dead center. 
In what follows, the results of calculations of a heat flux which 
can be gained in the investigated well at the depth L = 2870 m are 
given.
