An Improved Set of Design Criteria for Slotted Liners in Steam Assisted Gravity Drainage Operation
Download2020-01-01
Chenxi Wang, Mohammad Haftani, Jesus David Montero Pallares, Alireza Nouri
Slotted liners are widely used in steam-assisted gravity drainage (SAGD) wells to control sand production and sustain wellbore productivity. The slotted liner can provide desirable performance when appropriately designed. A literature review indicates a limited number of studies that offer design...

Consolidated air services at hub airports in the U.S. encourage passenger leakage. Compared to smaller airports, trips from large hub airports consume less fuel per passenger-kilometer. Trips from large hubs also result in less pollutants per passenger-kilometer. Attractive air services at large...

Before-and-after empirical Bayes evaluation of automated mobile speed enforcement on urban arterial roads
Download2019-11-12
Li, R., El-Basyouny, K., Kim, A.
Speeding is a leading factor in road collisions and is found to contribute to approximately one third of fatal collisions. Speed enforcement is one of the most common countermeasures used to reduce speed. However, a gap exists in the literature regarding the effectiveness of automated mobile...

This paper presents a critical state constitutive model for cemented sand. The model uses a single capped yield surface as a function of the void ratio, confining pressure, preconsolidation pressure, and stress ratio at the peak of the undrained effective stress path. To model the cemented...

Huixin Zhang, Hongbo Zeng, Ania C. Ulrich, Yang Liu
Laboratory-scale columns were employed to study the effect of oxygen and ionic strength on the transport of Pseudomonas aeruginosa PAO1 in porous media. In anaerobic experiments, cells were grown and transport experiments were conducted in a well-controlled anaerobic chamber. Cell surface...

This paper presents a constitutive model for describing the stress-strain response of sands under cyclic loading. The model, formulated using the critical state theory within the bounding surface plasticity framework, is an upgraded version of an existing model developed for monotonic behavior...

Mojtaba Rahimi, Dave Chan, Alireza Nouri
An elastoplastic constitutive model within the framework of bounding surface plasticity theory is adopted to predict the mechanical behaviour of soft sandstone under monotonic and cyclic loadings. In this model, the loading surface always passes through the current stress state regardless of the...

Ohi, Sabrena Jahan, Kim, Amy M.
This paper explores the application of count models to represent the relationship between flight disruptions and weather. Throughout the world, flights are regularly disrupted by delays at airports and in the terminal airspace, and less frequently by diversions and cancelations. Many delay...

This paper focuses on the study of proppant transport mechanisms in fractures during frac-packing operation. A multi-module, numerical proppant, reservoir and geomechanics simulator has been developed, which improves the current numerical modeling techniques for proppant transport. The modules...
