Transient multiphase flow simulation for unloading of frac hit gas wells
… flow simulation valid for unloading gas wells using nitrogen. It studies the behavior of nitrogen for unloading horizontal gas wells with gas injection in the annulus. The work investigates unloading non-Newtonian fluids such as those which invade offset wells when a frac hit occurs …

Mechanistic and probabilistic rate-time analysis of unconventional reservoirs
… significant uncertainty on the behavior of these wells and their production forecast. This work is divided into two parts. The first, develops simple physics-based models to further understand the underlaying mechanisms of unconventional production. The second, introduces a probability approach …

Enhancement of unconventional oil and gas production forecasting using mechanistic-statistical modeling
Unconventional oil and gas basins have rapidly become expansive and critical energy resource systems. However, accurately predicting highly variable well production rates remains challenging, given the typically poor subsurface characterization and complex flow behavior involved. This creates …

Three Essays on the Economics of Hydraulic Fracturing
… increased bonding requirements for horizontal wells introduced in West Virginia in December, 2011, on the probability of violation committed by those wells. Results suggest that the increased bonding requirement has reduced the probability of violation by 2.6 to 3.2 percentage points. Moreover, …

The socioeconomic consequences of the U.S. fracking boom
… In the second essay, we focus on analyzing how unconventional drilling and production techniques could affect oil and gas wastewater production. We find that horizontal wells drilled in shale regions after 2010 produced an increasingly larger amount of wastewater at the initial stage of …
