Abstract: 

The Upper Cretaceous Wall Creek Sandstone Member of the Frontier Formation and the Turner Sandy Member of the Carlile Shale are two of the most prolific unconventional plays in the Powder River Basin (PRB) of Wyoming. From 2017 through 2018, the Wall Creek and Turner reservoirs accounted for 39 percent of the PRB’s and 21 percent of Wyoming’s oil production. The Turner was also the PRB’s highest non-coal gas-producing reservoir during this time period, accounting for 23 percent of all natural gas produced from the basin.

This presentation will discuss research into what influences production from the PRB Wall Creek and Turner reservoirs. Wall Creek-Turner oil and gas production is graphically compared to the producing interval lengths and lateral orientations of horizontal wells, completion techniques such as hydraulic fracturing stages, slurry and proppant volumes, and operator-specific trends over time. Interpolated surfaces and contours are used to spatially compare basin-wide production trends to reservoir geologic characteristics, including formation depth, thickness, pressure, temperature, regional structural features, and hydrocarbon compositions such as crude oil API gravity, gas-oil ratios, and gas-fraction ratios. The graphical, spatial, and statistical comparisons of these variables suggest that hydrocarbon production from the complex PRB Wall Creek-Turner reservoir system is influenced more by geology than by horizontal well completion techniques.


The Wyoming State Geological Survey will continue to refine these evaluation techniques in order to better understand all of Wyoming’s Upper Cretaceous reservoirs.

Speaker Bio: Rachel Toner has been employed as a WSGS oil and gas geologist since March 2013. A native of Sheridan, Wyoming, she received B.S. and M.S. degrees in geology from the University of Wyoming. Her current work at the WSGS focuses on researching reservoir and well completion characteristics that explain production trends in the Powder River and Denver Basins' stacked unconventional reservoirs. She also develops and maintains online GIS mapping platforms for Wyoming's oil and gas reservoir and infrastructure data. Outside of work, Rachel enjoys traveling, playing tennis and softball, camping, and dogsledding with her Siberian huskies.
