Several sand control techniques have been used in SAGD wells in Western Canada. For most projects, slotted liners have been the sand control of choice for its economics, ease of use, and acceptable performance. Careful design of the slot geometry is crucial to maintaining...

Generally, fuzzy models, especially rule-based models, are designed in a monolithic manner, meaning that all data are used en bloc to design the model. At the same time, there is a visible need to cope with the ever-increasing volumes of data (both in terms of the number of data and their...

Three datasets of historical dam failures that are filtered to be able to evaluate empirical equations for peak flow, breach formation time, and average breach width. Various assumptions and estimates have been made to expand the applicability of each dataset. Given the magnitude of uncertainty...

Airspace Flow Programs (AFPs) assign ground delays to flights in order to limit flow through capacity constrained airspace regions. AFPs have been successful in controlling traffic with reasonable delays, but a new program called the Combined Trajectory Options Program, or CTOP, is being explored...

Productivity measurement is a concern for both construction practitioners and researchers. In construction, productivity can be measured at three levels: activity, project, and industry. At the project level, previous studies focused on measuring the productivity of specific activities. In...

The term advanced work packaging (AWP), coined by the Construction Industry Institute (CII), refers to a disciplined process for project planning and execution; it was developed to address challenges such as cost and schedule overruns in the industrial construction sector. Case studies conducted...

In this study, we introduce and develop a novel decision-making model that provides an original solution to problems of renewable energy site planning. The main idea is to construct a comprehensive and systematic methodology of ranking alternatives encountered in the environment of multicriteria...

This paper presents a model for the investigation of sandstone degradation and sand production mechanisms coupled with fluid flow analysis using the Discrete Element Method (DEM). The model was used to investigate the effects of in-situ stresses and flow rate on sand production. We developed a...
