This paper reviews the state-of-the-art experimental and theoretical methods on fines migration around Steam Assisted Gravity Drainage (SAGD) wellbores. The in-situ migratory particles can deposit in the pore space and result in pore throat plugging within the porous medium. This process...

Slotted liners have been widely used in steam-assisted gravity drainage (SAGD) wells owing to their low cost and superior mechanical integrity. Multiple factors affect the performance of slotted liners, such as particle size distribution (PSD) of formation sands, aperture size, slot density,...

Earthmoving operations are equipment-intensive processes that rely heavily on the proper selection of the equipment fleet and proper scheduling of associated tasks. Early equipment planning decisions have direct implications on schedules, costs, and more importantly, the environmental performance...

Accelerating the dewatering of oil sands tailings is a crucial challenge to the oil sands industry. Fresh tailings (15–20% by weight solids) and mature tailings (30–35% by weight solids) dewater slowly over a period of decades or centuries, and have resulted in the accumulation of 1,075 Mm3 of...

Construction companies continuously seek to improve risk analysis techniques to determine the contingency of projects. Construction risk assessment relies on a group decision-making (GDM) process, in which a heterogeneous group of experts provides their opinions to determine the probabilities and...

We present a scheduling model for an urban mobile photo radar speed enforcement (MPE) program. An MPE program utilizes automated photo radar technology to capture speed limit violators, towards an aim to reduce speeding and thus, improve traffic safety. We propose a binary quadratic program that...

Estimating erosion rate of solid particles in a porous medium is of interest to geotechnical engineers; which use analytical or numerical models for this purpose. Constitutive law of erosion is a key component in the development of such models. These models estimate the solid erosion rate as a...

The Level of Traffic Stress (LTS) framework is widely used to assess the suitability of roadway environments for cycling. Its main strength is the identification of infrastructure characteristics that meet the needs of different cyclist groups. The four levels of infrastructure ratings, LTS 1 to...
