Why do the wellhead leaks occur? New seals Worn seals (9 mo) Typical replacement of the seals is every 3 – 12 months. When Oil/w Oil/water leak ter leaks can not be stopped by adjustments, installation of new seals occurs. As the seals’ shape deteriorates, the potential for leakage increases.

Small Leaks are Deceiving Small Leaks are Deceiving  One drop of oil every 10 seconds is  One drop of oil every 10 seconds is extremely difficult to observe extremely difficult to observe  One drop of oil every 10 seconds equals 3.6  One drop of oil every 10 seconds equals 3.6 litres per day, 108 litres per month or 1314 litres per day, 108 litres per month or 1314 litres per day, 108 litres per month or 1314 litres per day, 108 litres per month or 1314 litres per year litres per year  There are 55 000 conventional oil wells in  There are 55 000 conventional oil wells in Canada using pumpjacks Canada using pumpjacks  Multiply 1314 litres by 5500 (10%) well sites  Multiply 1314 litres by 5500 (10%) well sites and the total equals over 7 million L/yr and the total equals over 7 million L/yr
