This publication presents the following data from 11 of those 27 wells: general information, well core images, depths to specific stratigraphic units, well core gamma ray logs in LAS format, well log information in LAS format, geological and drilling history reports in Adobe Acrobat PDF format, and permeability and porosity data.
