The wells were drilled and pipe was set during the first quarter from Warren’s Mirabelli and Ruark pads within its acreage block in Wyoming County, Pa., acquired last year (OGJ Online, July 7, 2014). Completion operations commenced in July.
Warren notes the Upper Marcellus is 180-ft thick, compared with the Lower Marcellus in the same area measuring 120 ft in thickness. Offset Lower Marcellus wells were monitored during fracturing operations and indicated no communication with the Upper Marcellus.
The company says a successful test of the Upper Marcellus could potentially add more than 40 additional well locations on its acreage block. No reserves were booked by Warren at yearend 2014 for the Upper Marcellus locations.
“Warren’s first two Upper Marcellus wells were drilled with the intent to test a wide swath of our acreage block,” said Lance Peterson, Warren’s interim chief executive officer. “Warren is very encouraged by the early results from these wells, and we expect to see these wells continue to clean up and experience increased flow rates.”
Warren also notes that it has pipeline systems and pads already in place to support drilling of additional wells in the Upper Marcellus.
