Revised productivity index equation to improve transient history match for the Capacitance Resistance Model
… of this model to unconventional reservoirs, a productivity index model that works well in transient flow regime should be investigated. In this thesis, two different productivity models are proposed. The first is the combined productivity index model. This model originates from the analytical …

Gas Deliverability Using the Method of Distributed Volumetric Sources
Productivity index (PI) is an important indicator of a well?s production capacity. For conventional reservoirs, well productivity is usually calculated using the pressure response of the reservoir in its pseudosteady-state period. There are numerous studies for different well completion schemes …

Factors Influencing Mussel Abundances across Southwest USA Rivers: A Test of an Underlying Assumption of the More-Individuals Hypothesis
… More-Individuals Hypothesis (MIH) predicts that productivity regulates organismal abundances, such that more productive systems support a greater number of individuals, and therefore species richness. Previous assessments of the underlying assumption of MIH (i.e., positive relationship between …

Three empirical essays on mergers and regulation in the telecommunications industry
… Essay 1: This study has attempted to measure the productivity growth associated with 25 incumbent local exchange carriers (ILECs) over the period 1996-2005 using a Malmquist productivity index. The average efficiency scores for our sample companies have not changed significantly between 1996 and …
