Solutions for killing the well

Well killing fluids that prevent contamination of formation:

• For density of 1050-1200 kg/m3 on the basis of salts KCl and NaCl without solid phase; 
• For density of 1200-1500 kg/m3 on the basis of salts KCl and NaCl with protective functions and content of calcium carbonate from 100 to 500 kg/m3 ; 
• For density of 1300-1400 kg/m3 on the basis of salts CaCl2 without solid phase; 
• For density of 1400-1600 kg/m3 on the basis of salts CaCl2 with protective functions and content of calcium carbonate from 100 to 500 kg/m3 ; 
• For density of 1500-1800 kg/m3 on the basis of salts NaBr and  CaBr2 without solid phase;
• For density of 1700-1900 kg/m3 on the basis of salts NaBr and  CaBr2 with protective functions and content of calcium carbonate from 100 to 500 kg/m3 ; 
• For density of 900-1000 kg/m3 on hydrocarbon basis with protective functions for abnormally low formation pressures; 
• Special fluids on hydrocarbon base with protective functions with density of 1000-1200 kg/m3;
