Random Update Of The Marcellus - Utica -- June 10, 2016

This post is added to put the Piceance Basin in western Colorado in perspective. See this link to the Piceance, June 9, 2016.

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)

Marcellus:

• 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 

Burket/Geneseo:

• 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
