The time it takes for a shale producer to drill a well has been a major focus for the past decade. A new report says the industry should place equal weight on how long it takes a well to actually deliver first oil. The move will bolster Austin-based Parsley’s holdings in the Delaware Basin, giving it a contiguous 120,000 net acres opposite of its original Midland Basin focus area. Noble’s first row of wells in its massive Mustang project is helping increase the operator’s DJ Basin output, and similar results are soon expected in the Delaware Basin. Production and proved reserves in the Permian Basin’s Wolfcamp Shale and Bone Spring Formation are reaching new heights, and a new assessment from the US Geological Survey indicates the industry is just scratching the subsurface when it comes to what may be technically recoverable.
