Life cycle environmental impact comparison of bioelectrochemical systems for wastewater treatment
(
Elsevier B.V.
, 2019 , Conference Paper)
Bioelectrochemical systems (BESs) are developed to transform the energy harvested from the biomass into electricity. Different types of BESs including microbial fuel cell (MFC), microbial electrolysis cell (MEC), and ...
Environmental degradation of 30 to 50 years old reinforced concrete structures in Qatari climate
(
Advanced Engineering Solutions
, 2017 , Conference Paper)
This paper presents the results of a field survey carried out on three reinforced concrete (RC) structures built respectively in 1960's 1970's and 1980's to determine the main load (environmental) and resistance (concrete ...
Life cycle assessment of particulate recycled low density polyethylene and recycled polypropylene reinforced with talc and fiberglass
(
Trans Tech Publications Ltd
, 2011 , Conference Paper)
Although recycled polymers and reinforced polymer composites have been in use for many years there is little information available on their environmental impacts. The goal of the present study is to analyze the environmental ...
Processing and characterization of palm fiber-polypropylene composites
(
Trans Tech Publications Ltd
, 2011 , Conference Paper)
Composites of palm fiber and polypropylene were compounded using a mixing device at various temperatures, mixing times, and mixing intensities. Two mixing options were utilized. Either the mixing device was mounted with a ...

Effectiveness of pyrrolidinium based ionic liquids in flow assurance: Preventing hydrates formation in offshore sub-sea pipelines
(
AIChE
, 2015 , Conference Paper)
The formation of hydrates within the offshore subsea pipelines is a major challenge to flow assurance in oil and gas industry. Annually, the industry spends large amount of money on thermodynamic inhibitors like methanol ...
Applications of Machine Learning Methods to Predict Hole Cleaning in Horizontal and Highly Deviated Wells
(
Society of Petroleum Engineers (SPE)
, 2023 , Conference Paper)
Machine learning (ML) has become a robust method for modeling field operations based on measurements. For example, wellbore cleanout is a critical operation that needs to be optimized to enhance the removal of solids to ...
A Mechanistic Model for Wellbore Cleanout in Horizontal and Inclined Wells
(
Society of Petroleum Engineers (SPE)
, 2021 , Conference Paper)
The accumulation of rock cuttings, proppant, and other solid debris in the wellbore caused by inadequate cleanout remarkably impedes field operations. The cuttings removal process becomes a more challenging task as the ...
Investigation of Matrix Damage and Remediation Methods of Preformed Particle Gel Conformance Control Treatments in Carbonate Reservoirs
(
Society of Petroleum Engineers (SPE)
, 2022 , Conference Paper)
Preformed Particle Gels (PPGs) have been widely applied to control excessive water production in mature oil fields with fractures or fracture-like features, especially in sandstones, but with limited attention to carbonates. ...
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. ...
