Permian "Super Basin" Holds Up To $3.3 Trillion In Untapped Oil -- Bloomberg; Peak Oil? What Peak Oil? -- September 25, 2017

Data points:

• Permian Basin, Texas and New Mexico: 60 billion to 70 billion bbls of yet-to-be-pumped crude oil
• enough to supply every refinery in the US for 12 years
• $3.3 trillion market value at current prices
• three-year study (so the data is already a bit old)
• based on data from more than 400,000 wells
• the estimate may grow as IHS geologists extend their analysis to deeper zones
• the assessment may boost Pioneer's assertion that the Permian is a 75-billion-bbl field that may rival Saudi Arabi's massive Ghawar field
• in November, 2016, the USGS estimated that just one layer of the Permian -- the Wolfcamp -- holds 20 billion bbls of crude (recoverable)
