Mathematical Models for predicting CO2 Density and Viscosity for Enhanced Gas Recovery and Carbon Sequestration (2025)
Journal Article

There is limited work on mathematical correlations in place for predicting density and viscosity of supercritical carbon-dioxide (CO2), necessary for Enhanced Gas Recovery-Carbon Sequestration (EGR-CS) operations. In this work, three categories of ma... Read More about Mathematical Models for predicting CO2 Density and Viscosity for Enhanced Gas Recovery and Carbon Sequestration.

Flare Pollution Loads and Carbon-Dioxide Effect on Rainwater Acidity in Niger-Delta: A Review, Investigation and Model for Safe Living Quarter (2024)
Journal Article

Carbon-dioxide does not only affect climate change, but also contribute tremendously in acidification of rain water. Hazard identification and risk assessment are fundamental components of effective risk management, specifically in sensitive areas wh...

Investigating the flow behaviour of CO2 and N2 in porous medium using core flooding experiment (2021)
Journal Article

Several researchers employed N2 to augment CH4 recovery efficiency and CO2 sequestration during the Enhanced Gas Recovery (EGR) process in consolidated rocks. To our knowledge, there has been limited data backing the reason why CO2 experienced a more...

The role of N2 as booter gas during Enhanced Gas Recovery by CO2 flooding in a porous medium (2021)
Journal Article

Most research on CO2 flooding is focusing on CO2 storage than CH4 recovery and mostly simulation-based. To our knowledge, there have been limited reported experimental on CO2 injections capable of unlocking a high amount of the residual methane due t...

Enhanced oil recovery through integration of ultrasound and polymer flooding (2020)
Thesis
Hassan, K. Enhanced oil recovery through integration of ultrasound and polymer flooding. (Thesis). University of Salford

Initially, when an oil well is drilled the oil gushes to the surface at high pressure. However, with time the pressure declines leaving more than 50% of the oil trapped in the reservoir. Even with the introduction of current technologies, more than 4... Read More about Enhanced oil recovery through integration of ultrasound and polymer flooding.

Enhanced gas recovery by nitrogen injection : the effects of injection velocity during natural gas displacement in consolidated rocks (2020)
Journal Article

The choice of the flow velocity in EGR thus becomes important since higher injection rates could lead to premature
mixing of the fluids and lower injection rates generally provide longer resident times for the fluids in
contact and indirectly incre... Read More about Enhanced gas recovery by nitrogen injection : the effects of injection velocity during natural gas displacement in consolidated rocks.

Alternating N2 gas injection as a potential technique for enhanced gas recovery and CO2 storage in consolidated rocks : an experimental study (2020)
Journal Article

The promotion of enhanced gas recovery (EGR) and CO2 storage is still shrouded in contention, and is not well
accepted, due to the excessive in-situ CO2 mixing with the nascent natural gas. This adulterates the recovered
CH4 and thus, results in a... Read More about Alternating N2 gas injection as a potential technique for enhanced gas recovery and CO2 storage in consolidated rocks : an experimental study.

Enhancing the performance of Xanthan gum in water-based mud systems using an environmentally friendly biopolymer (2020)
Journal Article
Akpan, E., Enyi, G., & Nasr, G. (2020). Enhancing the performance of Xanthan gum in water-based mud systems using an environmentally friendly biopolymer. Journal of Petroleum Exploration and Production Technologies, 10, 1933-1948. https://doi.org/10.1007/s13202-020-00837-0

Xanthan gum is commonly used in drilling fluids to provide viscosity, solid suspension, and fluid-loss control. However, it is sensitive to high temperatures and not tolerant of field contaminants. This paper presents an experimental study on the eff... Read More about Enhancing the performance of Xanthan gum in water-based mud systems using an environmentally friendly biopolymer.

Flow characteristics through gas alternating gas injection during enhanced gas recovery (2019)
Presentation / Conference
Mohammed, N., Abbas, A., Enyi, G., & Nasr, G. (2019, October). Flow characteristics through gas alternating gas injection during enhanced gas recovery. Presented at SPE Gas & Oil Technology Showcase and Conference, Dubai, UAE

Gas and liquid flooding using carbon dioxide (CO2), nitrogen (N2), or brine solution have become one of the promising enhanced gas (EGR) and oil recovery (EOR) technologies for residual hydrocarbons (HCs) enhancement in conventional oil and gas reser...
