SUBSURFACE INJECTION OF WASTE-WATER INTO DEVONIAN CARBONATE FORMATION IN THE HEALTH RESORT USTROŃ

Abstract. 11.9–13.1% brine has been exploited by The Health Resort Ustroñ for therapeutic purposes. The used brine is treated and injected into the Devonian carbonate formation. About 50 cubic meters of used brine with TDS 3.5–4.0 g/dm3 is injected daily. In time of a few years of exploitation the decrease of subsurface injection debit has been observed. Continuous use the injection well causes its clogging. Injection well is acidized in order to counteract to the fall of the capacity. Maximum yield of injection well attained 9.85m3/h and decreased to 2.5 m3/h during exploitation. The yield of the injection well C-1 increased a few times after acidizing. In this paper the yield variability of the injection well C-1 was characterized.
