Real numbers on Marcellus Shale gas production

 
Potential gas production and actual gas production from Marcellus Shale wells became a hot topic during the summer of 2011. To wit, an SEC investigation. Financial investors need to know how accurate the predictions are of Marcellus Shale gas reserves, and the true productive life of Marcellus wells.

  While predicting gas reserves remains just a prediction, we have tracked 190 wells at over three dozen drilling locations with actual Marcellus gas well production numbers, to clearly show how much gas has been produced, and more importantly, how much gas production has declined over the first years of shale gas production.

 
The figures will surprise you. It has been shown that the average productive life of a Barnett Shale well is 7.5 years. From these early production results it looks as though these Marcellus wells may share that same short lifespan. The trend points to a 65-percent drop in production over the first 3 years, with further declines of 8 percent per year after that. Using that model, a Marcellus well's average productive life would be 8 years. Gas liquids (alternately listed as either condensate or oil) production drops just as fast, if not faster, than the methane production shown in the charts below.

The statistics for wells listed below cover a 48-month period (through 6/30/13) even though many of the wells are so new that production figures may only cover a few months. We have expanded the DEP statistics to show the average Mcf production per day (yellow column) making it much easier to compare the various reporting periods. Further information and photos of each of these drilling units is shown on individual web pages linked on the left navigation bar under "Marcellus Shale Wells."

“In 2009, Pennsylvania produced about 3.6 million barrels of crude oil (1 barrel = 42 gallons) and 273 billion cubic feet of natural gas. Most oil wells in the state produce only a few barrels of oil per week and average gas well production is less than 13 Mcf (thousand cubic feet) of natural gas per day (that’s about enough gas to fuel one all-gas household for a month). Though production per well isn’t much, nationwide these stripper wells are an important part of our domestic energy supply because there are hundreds of thousands of stripper wells producing oil and gas in the United States. In addition to the stripper wells, the new Marcellus Shale wells are greatly increasing the state’s total production. Production reported from Marcellus Shale wells averages about 950 Mcf per day.”

Note: The first Pennsylvania DEP reporting period covered 12-months (7/1/09-6/30/10) while each reporting period since then has covered a 6-month period)
