Where was PA’s Top Producing Marcellus Well in 2011? Dimock

The Pennsylvania Department of Environmental Protection released new gas well production data on Friday for the second half of 2011. Gas production was up an aggressive 40 percent in the second half of the year. PA now produces more gas than they consume, making the state a net exporter of natural gas.

Pennsylvania’s deep gas wells pumped out 607 billion cubic feet of gas between July and December, bringing the year’s total production to a milestone 1 trillion cubic feet – enough to surpass the amount of natural gas used in the state each year.

By the end of the year, 2,210 of the commonwealth’s shale wells were tied into pipelines and producing gas – a 35 percent increase in the number of producing wells since the first half of 2011 that helped account for a 40 percent jump in production.

The average amount of gas produced daily during the six-month period – 3.3 billion cubic feet per day – was slightly less than industry projections.

Eight of the 10 top-producing wells for the half were Cabot Oil & Gas Corp. wells in Dimock and Springville townships, Susquehanna County, including the top producing well, the King 2 in Dimock, which produced 3 billion cubic feet of gas.

Cabot’s King 2 well also had the best daily average production over the period, producing 16.5 million cubic feet per day.

The other top-producing wells for the period were a Range Resources well in Canton Twp., Washington County, and the Citrus Energy Corp. Ruark East 1H well in Washington Twp., Wyoming County.*

Along with more production comes more wastewater, but most drillers now recycle most of it.

The state’s Marcellus wells also produced 10 million barrels of wastewater during the last six months of 2011, about 500,000 barrels more than the amount produced during the first half of the year. A barrel is equal to 42 gallons.

More than three-quarters of the liquid waste – which includes both fluids from the drilling process and the salt- and metals-laden liquid that returns from a well after hydraulic fracturing – was either directly reused in new wells or taken to treatment plants that recycle it.

More than 1.7 million barrels of the waste fluid was trucked to deep disposal wells, mostly in Ohio.*
