Powder River Basin Regional Study

Rocky Mountains

The Powder River Basin Regional Study was designed to provide participating companies with detailed geological, petrophysical, and associated engineering characterization and evaluation of Muddy-Newcastle, Minnelusa-Leo, Dakota-Fall River and Frontier-Turner sandstones. The primary objectives for this study are as follows:

  • Describe, document, and interpret sandstone lithology, vertical sequences, and the character of various lithofacies present within conventional cores.
  • Define, document, and evaluate sandstone mineralogy, textural, and pore space properties for pay and potential pay identification.
  • Measure and analyze rock logging and fluid-flow parameters for samples representative of the spectrum of reservoir quality rock types from each of the four formations studied.
  • Correlate the basin-wide distributions of formations and zones of interest studied from normalized depth shifted wireline logs.
  • Analyze geological and petrophysical data from each formation in order to provide a better understanding of initial production performance for wells with DST's in the zones of interest and recommend revised or improved will completion and stimulation procedures.

The project contains a total of eighty-three (83) conventional cores of Muddy, Minnelusa, Frontier and Dakota Formations, along with available wireline logs, production history, and previous core analyses.

  • Eighty-three (83) wells
  • Muddy, Minnelusa, Frontier and Dakota formations
