EOR / POLYMER FLOODING
POWELTEC staff has been involved in all the major breakthroughs achieved in polymer EOR for 30 years. The design of the first olymer flood pilot in Daqing (the largest polymer flood project worldwide), the conception of the first heavy oil horizontal well poymer flood in Pelican Lake, and the first deep offshore polymer flood in Dalia are evidences of this leadership.
Remarkable results have been obtained in the treatment of Gas wells for ten years.
Drastic reduction of sand production was observed saving a lot of maintenance costs. The efficiency of POWELTEC's treatments last several years. Re-treatments have also been performed successfully.
WATER SHUT OF / CONFORMANCE CONTROL
POWELTEC WSO/ CC processes have been successfully applied in more than 100 field cases worldwide, i.e., gas wells, multi-layer waterflooded wells, heavy-oil horizontal wells, fractured reservoirs, sandstone and carbonate reservoirs.
