Effect of Fluid Rheology on the Performance of Fibrous Fluid in Horizontal Well Cleanout
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
The deposition of solids in the wellbore is a widely known problem encountered during drilling, completion, and intervention operations. Innovative cleanout fluids alleviate problems associated with inefficient hole cleaning. ...
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 ...
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 ...
Economic study on the production of dimethyl ether using wind-based electrolytic of hydrogen and carbon dioxide
(
American Institute of Physics Inc.
, 2023 , Conference Paper)
The world currently relies heavily on non-renewable energy, which is unable to sustain the needs of 7 billion people in the next 50 years. This paper discusses the use of an alternative fuel, Dimethyl ether (DME), which ...
Application of Artificial Neural Network Approach for the Kinetic Parameters Determination of Pyrolysis Aseptic Waste Packages
(
Institute of Electrical and Electronics Engineers Inc.
, 2023 , Conference Paper)
The thermal degradation behavior for the pyrolysis of aseptic packages was studied using thermogravimetric analyzer under nitrogen atmosphere at the temperature range of 50–900°C with five different heating rates (10, 20, ...
Development of novel blend poly (Ethylene Glycol) / Poly(Ethersulfone) polymeric membrane using N-Methyl-2-Pyrollidone and dimethylformamide solvents for facilitating CO2/N2gas separation
(
Elsevier
, 2020 , Conference Paper)
Carbon dioxide (CO2) emissions have been the main cause for anthropogenic climate change. To meet the growing demand for CO2 removal, membrane separation technology using blend membranes is a promising and attractive ...
