Unconventional drilling methods are used due to increasing scarcity of retrieving oil and gas using conventional methods. Not always, is a pocket of oil and gas available to be retrieved by drilling and pressure naturally allowing the flow of gas. In this case, unconventional drilling comes in handy. Unconventional is a method that allows to drill down, drill horizontally, and fracking occurs. This allows oil and gas to be flowing from tight sands that we normally could not retrieve with conventional methods of drilling. - Croft Production Systems
