This document contains numerous maps and diagrams related to the Niobrara shale play across Colorado, Wyoming, Nebraska, and other Rocky Mountain regions. It includes maps of the geographic extent and production of the Niobrara formation, as well as cross sections depicting the stratigraphy and fracture patterns. Charts show type curves, estimated ultimate recovery values, well spacing, lateral lengths, proppant usage, and production comparisons for the Niobrara play versus other major U.S. shale plays.
