Application of DFT in iron sulfide scale removal from oil and gas wells
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ...
Bridging the Energy-Water Gap in Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2012 , Conference Paper)
Industrial development and demographic growth come at a cost to the climate, not least on its impact on the water resources. The high demand on water usage and the associated production of wastewater requires stringent ...
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
Advanced wastewater treatment using microalgae: Effect of temperature on removal of nutrients and organic carbon
(
Institute of Physics Publishing
, 2017 , Conference Paper)
This study evaluated the use of mixed indigenous microalgae (MIMA) as a treatment process for wastewaters and CO2 capturing technology at different temperatures. The study follows the growth rate of MIMA, CO2 Capturing ...

A mechanistic gas kick model to simulate gas in a riser with water and synthetic-based drilling fluid
(
Society of Petroleum Engineers
, 2020 , Conference Paper)
This paper presents a simple mechanistic model to describe a gas kick in a drilling riser with water- based mud (WBM) and synthetic-based mud (SBM). This model can estimate key kick parameters such as the change in the ...
Treatment of saline wastewater and carbon dioxide capture using electrodialysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In this study, electrodialysis was used to achieve a combined action of capturing carbon dioxide and treating high-salinity water to produce hydrochloric acid, hydrogen gas, and carbonate and bicarbonate salts. Sodium ...
CO2 Absorption Capacity and its Enthalpy of Absorption in Aqueous Blend of MDEA/Piperazine/Arginine
(
Institute of Physics Publishing
, 2020 , Conference Paper)
In this work, the solubility data of CO2 in aqueous blends of N-Methyldiethanolamine, Piperazine and Arginine (MDEA/PZ/ARG) of a total concentration of two moles is presented. CO2partial pressure was varied from 9 to 99 ...
Improvement of PVA gel properties for cell immobilization
(
Avestia Publishing
, 2019 , Conference Paper)
This study investigates the characterization and the ability of polyvinyl alcohol (PVA) gel to be used in the area of wastewater treatment as biomass immobilization matrix. The PVA matrix was prepared through the ...
Investigation of gas-liquid flow using electrical resistance tomography and wavelet analysis techniques for early kick detection
(
American Society of Mechanical Engineers (ASME)
, 2021 , Conference Paper)
Gas kick is a well control problem and is defined as the sudden influx of formation gas into the wellbore. This sudden influx, if not controlled, may lead to a blowout problem. An accidental spark during a blowout can lead ...
