Effects of Pipe Rotation on the Performance of Fibrous Fluids in Horizontal Well Cleanout
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
The deposition of rock cuttings is a problem commonly faced during drilling, completion, and intervention operations. Using polymer-based fluids is a common technique to improve horizontal downhole cleaning. However, these ...
Rapid Curing Environmentally Degradable Polymeric Pill for Loss Circulation Treatment
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
Loss circulation is frequent while drilling in naturally fractured or depleted reservoirs, which is usually associated with high non-productive time (NPT). Moreover, naturally pre-existing fractures may propagate when fluid ...
Evaluating greywater and A/C condensate daily volume and water quality in urban settings
(
American Society of Agricultural and Biological Engineers
, 2011 , Conference Paper)
Due to increasing water demand as a result of population growth and improvement in living standards, many countries with arid climate are already facing water shortages that are being met by expensive desalination projects. ...
A/C condensate for water reuse: An approach towards environmental sustainability in Doha
(
American Society of Agricultural and Biological Engineers
, 2012 , Conference Paper)
A/C Condensate is a relatively untapped alternative source of water that might be readily available especially in hot arid climates. The objective of this study is to establish the feasibility of the A/C condensate as the ...
Numerical simulation of thermal buoyant wall jets
(2013 , Conference Paper)
The main focus of this study is on the near field flow and mixing characteristics of the thermal
wall jets. A numerical study of the buoyant wall jets discharged from submerged outfalls from cooling
systems of power ...
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)
In this study, a new finite volume method is developed for shallow water equations on a rotating
frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or
numerical damping for ...
Bio-Based Self-Healing Concrete for Sustainable and Durable Concrete Infrastructure
(
Qatar University Press
, 2023 , Conference Paper)
In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this ...
Performance of Mild Steel and Corrosion-Resistant Steel Rebars in Chloride-Contaminated Concrete
(
Qatar University Press
, 2023 , Conference Paper)
Reinforced concrete (RC) infrastructure in Arabian Peninsula is subjected to harsh climatic conditions of high temperatures, humidity, and airborne chlorides and there is a high concentration of salts in seawater and soils. ...
LIME: Long-Term Forecasting Model for Desalination Membrane Fouling to Estimate the Remaining Useful Life of Membrane
(
Springer Science and Business Media Deutschland GmbH
, 2023 , Conference Paper)
Membrane fouling is one of the major problems in desalination processes as it can cause a severe drop in the quality and quantity of the permeate water. This paper presents a data-driven approach for long-term forecasting ...
High and Ultra-high Performance Concretes: A Solution to Reinforced Concrete Durability under Harsh Climate of Arabian Gulf
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Reinforced concrete (RC) infrastructure in the Arabian Gulf region deteriorates under
severe environmental conditions after only short service life. To overcome this problem,
it is imperative to employ high-quality concretes ...
