WhatsApp: +86 18203695377Canada began producing conventional oil in the late 1890s and conventional natural gas in the early 1900s. By contrast, unconventional resources are trapped in reservoirs with low permeability, meaning little to no ability for the oil or natural gas to flow through the rock and into a wellbore. In order to produce from unconventional reservoirs ...
