Natural gas production from the Marcellus shale has surpassed 15 bcfd through July and now represents 40% of US shale gas production, making it the largest producing shale gas basin in the country, according to the US Energy Information Administration’s Drilling Productivity Report.
While the region’s rig count has leveled off at around 100 rigs over the past 10 months, improvements in drilling productivity have enabled operators to more efficiently support new wells.
EIA expects wells coming online in August to add more than 600 MMcfd to existing production, more than offsetting a drop in production due to existing well decline rates, thus increasing the production rate by 247 MMcfd.
Marcellus production in recent years has shot up to record levels after accounting for just 2 bcfd in 2010, resulting in record gas storage injections, multiple pipeline expansion projects to remedy bottlenecks, and stabilized or decreased prices (OGJ Online, Apr. 25, 2014).
