Outside Publication: Energy & Fuels
Shale is an increasingly important source of natural gas in the United States. The gas is held in fine pores that need to be accessed by horizontal drilling and hydrofracturing techniques. Understanding the nature of the pores may provide clues to making gas extraction more efficient. We have investigated two Mississippian Barnett Shale samples, combining small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) to determine the pore size distribution of the shale over the size range 10 nm to 10 μm...

2,263 scanned logs of various types including gamma ray, sonic, neutron, caliper, and lithologic descriptions are available for 621 different wells in the Piceance Basin of western Colorado. Logged intervals generally focus on the Green River Formation which contains large amounts of oil shale in this area. Image quality varies considerably with the condition of the starting material. Files are PDFs or TIFFs and file size ranges up to 560 megabytes with and an average size of 33 megabytes. This page contains data downloads for Piceance Basin, 2010 Oil Shale Assesment, compiled from DDS-69-Y.
