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. ...
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 ...
Advanced Block Copolymer Membranes for Oily Industrial Wastewater Treatment
(
Qatar University Press
, 2023 , Conference Paper)
Tremendous amounts of oily wastewater are produced daily from industrial processes, including petrochemical, textile, leather, and steel processing. This wastewater is a huge challenge to the environment and industry uses ...
Adsorption of Congo Red Dye Using Activated Carbon-Fe3O4 Composite
(
Qatar University Press
, 2023 , Conference Paper)
Activated Carbon-Fe3O4 composites were synthesized using co-precipitation method and used in batch experiments to adsorb Congo red dyes. The effect of adsorbent dosage, temperature and initial dye concentration was ...
Flow mapping of multiphase flows using a novel single stem endoscopic particle image velocimetry instrument
(
Institute of Physics Publishing
, 2011 , Conference Paper)
Particle image velocimetry (PIV) is a successful flow mapping technique which can optically quantify large portions of a flow regime. This enables the method to be completely non-intrusive. The ability to be non-intrusive ...
Carbon dioxide hydrogenation to value-added products using Cu-based catalytic materials
(
Institute of Physics
, 2023 , Conference Paper)
In this work, we report on the synthesis and evaluation of catalytic materials composed of copper/calcium oxide/alumina (Cu/CaO/Al2O3) for carbon dioxide conversion to value-added products. Catalytic materials were synthesized ...
Effect of the length of silicon nano-dot/wire on band gap
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2014 , Conference Paper)
We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ...
Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
