SideT Drill=Old Wells back in play29 May 2016 00:39
Research ' With discoveries thinning out, oil producers face an age-old problem: new, profitable wells are in decline just as the financial resources needed for increased production are on the rise. A potential solution for producers, which bypasses the uncertainty of making new discoveries, is to boost production from existing wells. Average recovery rates in conventional wells worldwide hover around 34%, meaning that two-thirds of all discovered oil remains untapped. To that end, producers are turning to hydraulic fracturing and horizontal drilling to increase output from low-productivity conventional wells—and seeing substantial increases in recovery rates. The Canadian Cardium play in the Alberta Deep Basin, for example, has been in production since the 1950s— but with steadily diminishing returns through the first decade of the 2000s. Since 2009, horizontal drilling has increased production from 33,000 barrels per day to almost 114,000. GN GL Keep the faith.
