Fracing is sending a specially designed fluid down the oil or gas well at high pressure and blowing it out into the reservoir rock to create cracks and channels through which the hydrocarbons can get to the well.
How big an impact has multi-stage fracing (MSF) had? Once the industry figured out how to frac the shale rock formations to get at all the natural gas they hold, it opened up huge new reservoirs across North America, and is the leading reason on the supply side as to why the price of natural gas has plummeted.
It’s exciting for the industry and investors because improvements to MSF are still being made – the industry is continually getting more production, more fracs, or stages, per well. Initial fracing was done in 4 stages over 500 meters. Now you can see 16 stages over a 1600 metre horizontal length. (One active fracing company said this week that the average Montney well has 7-12 fracs).
The industry hasn’t hit the end of what MSF can do; innovation is still happening. And they’re fracing tighter and narrower reservoirs or payzones. One of the largest oil discoveries in North America is the Bakken play, which straddles the Dakotas and Saskatchewan (the US Geological Society estimates over billion barrels are there) – but the zone can often be as narrow as 3 metres, or 9.5 feet.
