Released Today By EIA: Implications Of Increasing Light Tight Oil Production For US Refining -- May 5, 2015

Link is here.

This would have been nice to have several years ago to help folks understand the types of crude oil being produced.

The full report is 149 pages but I believe the summary is found in three sections (on one page):

2.1: Overview
2.2: Low production case
2.3: High production, current crude export restrictions
2.4: High production, no crude export restrictions

This is the type of data that Congress will use to defend whatever position they take with regard to exports.
