The Montney play is undoubtedly Canada's most successful unconventional play. Investment has persisted through the price downturn and activity is on the rise in 2017 both on the British Columbia and Alberta portions of the siltstone play. Part of the economic success is linked to a sharper focus on the core, liquids-rich areas and lower service costs. But improvements in well productivity also make a massive difference. We have looked at the completions data available from the British Columbia Oil & Gas Commission to analyze what is changing in well design within this particular province. We note the trends occurring for number of frac stages, lateral length, proppant loading and fluid use, looking at everything from completion type to saline versus freshwater usage. This report identifies which completion techniques are having the biggest impact on production and how trends differ by subplay and by operator.
