More Early Unconventional Wells

This post continues my series on unconventional wells that have been omitted from the Pennsylvania Department of Environmental Protection’s Act 13 reporting, with a look back at some wells from 1979-1981.

Commenting on this period, Patchen et al. (1982: 1958) write: “The Devonion shales of Pennsylvania, which have produced gas (normally in uncommercial quantities) since 1860, were the target of several successful drilling attempts in 1981.” These drilling attempts resulted in “three new pools discovered in the deeper shale zones, including the Upper Devonian West Falls, Sonyea, and Genessee formations, and the Middle Devonian Marcellus Formation.”

According to the Pennsylvania Geological Survey’s Subsurface Rock Correlation Diagram (Carter, 2007), the West Falls Formation includes the Rhinestreet Shale; the Sonyea Formation includes the Middlesex Shale; the Genessee Formation includes both the Geneseo Shale and the Burket Shale; and of course, the Marcellus Formation includes the Marcellus Shale. All five of these shales are stratigraphically below the Elk Sandstone, and thus, any wells drilled into these formations are subject to unconventional gas well fees under Act 13, CHAPTER 23 § 2302.

One of these wells was the Combustion Engineering Fee #1 well (Permit #003-20980), drilled in Allegheny County on March 25, 1979, and completed that year in the Marcellus and Genesse formations. According the Pennsylvania Department of Environment Protection’s Oil and Gas Reporting website, this well was still producing gas 365 days a year in 2005, 2007 and 2008. But contrary to Patchen et al.’s (1982) report, the well is reported as “N” in the Marcellus Well field.

UPDATE: On February 4, 2015, I received the following email about the Combustion Engineering Fee #1 well.

Joel – Per this article you wrote I was the PM on the job working for Combustion Engineering at the time, and I somehow found this article. The well was fully DOE funded, the only Marcellus we did on it was to do one fracture, at 7,509 feet, that number sticks with me, take a sample to Mellon Institute for testing, and we then re-fractured at the higher sands in order to get enough gas out to heat the facility. The shale was way too tight for 1979 technology! Just thought you may want to know since your article notes there is really no record of Marcellus Production.
Thanks – Bob Necciai

Another two wells were drilled in Clarion County: the Conner #1 well (Permit #031-2076) and the Minich #2 (Permit #031-20864). Both wells were drilled by Gearhart and Odell and completed in the West Falls, Sonyea and Genessee formations (meaning the Rhinestreet, Middlesex, Geneseo and Burket shales). According to the Pennsylvania Department of Environment Protection Oil and Gas Reporting website, the Conner #1 produced gas in 2002, 2004 and 2005. However, these wells were not reported to the Pennsylvania Public Utility Commission by the Department as required by Act 13. I’ve added all three wells to the spreadsheet of missing Act 13 unconventional wells.

Finally, Patchen et al. (1982: 1980) report on three failed exploratory wells drilled to the Helderberg Group and another drilled to the Hamilton Group. Very possibly, these four wells are also liable for Act 13 unconventional gas well fees. The Hamilton Group includes the Marcellus Shale and the Helderberg Group includes the Mandata Shale. These wells included Permits MCK-39885, SOM-20103, TIO-20104 and WES-21705.
