Cline Shale
As of 2013 the Cline Shale, also referred to as the "Wolfcamp/Cline Shale", the "Lower Wolfcamp Shale,",[1] or the "Spraberry-Wolfcamp shale",[2] or even the "Wolfberry",[3] is a promising Pennsylvanian oil play east of Midland, Texas which underlies 10 counties: Fisher, Nolan, Sterling, Coke, Glasscock, Tom Green, Howard, Mitchell, Borden and Scurry County, Texas.[1] Exploitation is projected to rely on hydraulic fracturing.[4]
an organic rich shale, with Total Organic Content (TOC) of 1-8%, with silt and sand beds mixed in. It lies in a broad shelf, with minimal relief and has nice light oil of 38-42 gravity with excellent porosity of 6-12% in thickness varying 200 to 550 feet thick.[1]
Estimated total recovery is 30 billion barrels.[5][6]
