| A technology for isolation of ground waters has been developed. Water isolation compounds based on sodium silicate (water glass) – a silicate gel compound SGC and hydrophobic compounds HPhC and HPhC-1 – have been tested. SGC is the best one to be applied in bitumen wells with injectivity of 20 m3/h, HPhC and HPhC-1 in wells with 20-30 m3/h and over 30 m3/h injectivity, respectively. |
