    A hedonic model for property values in proximity of hydraulic fracturing wells by Sackman, Henry

    This paper investigates the potential impact nearby unconventional gas wells may have on the value of single-family homes within Bradford County, Pennsylvania. A hedonic pricing model is utilized to determine if nearby unconventional shale wells impacted the prices of these properties from 2013 through 2014. Both OLS and single-log regression models were run using the number of active unconventional wells within five and ten kilometers as the exogenous variables of interest in addition to the characteristics of the properties. Prices of homes that had unconventional wells within ten kilometers did not seem to be affected, but when the distance was reduced to five kilometers, the value of properties declined by over four thousand dollars.

    The efficacy of various hydraulic fracturing techniques in the Denver Basin by Diamond, Colby G.

    Hydraulic fracturing is a stimulation technique that allows for the commercial exploitation of oil and gas from reservoirs that would be otherwise uneconomical. Designing the fracture stimulation is a complicated process with many considerations, and better designs will ultimately improve production performance. Using fracture stimulation data and oil and gas production data for 33 wells in the Denver Basin, OLS regressions help determine which fracture stimulation design variables create the largest increases in post-fracture oil and gas production. This study finds that post-fracture cumulative production, particularly gas, is affected by the completion type—whether a new or existing geological formation in the well is fractured; the fracture type—the specific fracture treatment being used, such as a hybrid frac or water frac; and the average injection rate of the fracture treatment. These results help elucidate which treatment variables have the largest effect on production performance.
