Utica:
- EIA produces new maps of the Utica shale, May 2, 2016. Some data points:
- the Utica includes two formations: the Utica formation and the deeper Point Pleasant formation
- 60,000 square miles: Ohio, West Virginia, Pennsylvania, New York
- the deeper Point Pleasant is more often targeted right now, more productive
- most of the most productive Point Pleasant in eastern Ohio, western Pennsylvania
- Point Pleasant deepest in SW Pennsylvania; depths more than 13,000 feet
- most productive wells in the Utica formation: 5,000 to 11,000 feet
- Utica: as thick as 200 - 300 feet in northwest Pennsylvania
- Point Pleasant: more than 200 feet thick in central Pennsylvania
- 2012, USGS survey: 38 trillion cubic feet; 940 million bbls oil technically recoverable
- From a July, 2015, West Virginia study:
- original gas-in-place (OGIP): 3,192 trillion cubic feet
- original oil-in-place (OOIP): 82,903 million bbls (sic)
- current technology, recovery factor:
- gas: 28%
- oil: 3%
- technically recoverable
- gas: 782 trillion cubic ft (vs USGS estimate of 38 trillion cubic feet)
- oil: 1.96 billion bo (vs USGS 940 million bo)
- EIA map of the Marcellus, includes production wells from 2003 - 2014
- not as deep, not as thick as the Utica
- the most recent USGS Marcellus survey was done back in 2011
- technically recoverable:
- gas: 84 trillion cubic feet
- NGLs: 3.4 billion bbls
- Previous USGS estimate, 2002:
- gas: 2 trillion cubic feet
- NGLs: 0.01 billion bbls
- or, "the upper Devonian Burket/Geneseo shale"
- first posted at the blog here
- Ohio Oil & Gas Journal, May 14, 2015
- Appalachia's 3rd resource lay
- probably not as big as the other two, but likely to be significant as a stacked play
- liquids-rich; possibly with flat decline curves
- Burket: all of West Virginia, most of Pennsylvania
- Geneseo: northwest Pennsylvania, New York state
- thickness: from a few feet to 150 feet in central Pennsylvania
- early indications: significantly over-pressured; significant geo-steering problems
- gas: 2 trillion cubic feet
- NGLs: 0.01 billion bbls
