Effects of gravity on flow behaviour of supercritical CO2 during enhanced gas recovery and sequestration (2018)
Presentation / Conference
Abba, M., Abbas, A., Saidu, B., Nasr, G., & Al-Otaibi, A. (2018, November). Effects of gravity on flow behaviour of supercritical CO2 during enhanced gas recovery and sequestration. Poster presented at Fifth CO2 Geological Storage Workshop, Utrecht, The Netherlands

A core flooding experiment was carried out to simulate an Enhanced Gas Recovery (EGR) process to inject supercritical Carbon Dioxide (SCO2) into a core sample saturated with methane (CH4). This was done to investigate the flow behaviour of the inject... Read More about Effects of gravity on flow behaviour of supercritical CO2 during enhanced gas recovery and sequestration.

Enhanced gas recovery by CO2 injection and sequestration : effects of temperature, vertical and horizontal orientations on dispersion coefficient (2018)
Presentation / Conference
Abba, M., Abbas, A., Nasr, G., & Al-Otaibi, A. (2018, November). Enhanced gas recovery by CO2 injection and sequestration : effects of temperature, vertical and horizontal orientations on dispersion coefficient. Presented at The Abu Dhabi International Petroleum Exhibition & Conference (ADIPEC), Abu Dhabi

Enhanced gas recovery (EGR) by CO2 injection and sequestration is receiving increased attention within the research community. This is as a result of its potential to be an avenue for the simultaneous additional recovery of natural gas from the reser...

Experimental investigation on the impact of connate water salinity on dispersion coefficient in consolidated rocks cores during enhanced gas recovery by CO2 injection (2018)
Journal Article
Abba, M., Al-Otaibi, A., Abbas, A., Nasr, G., & Abdulkadir, M. (2018). Experimental investigation on the impact of connate water salinity on dispersion coefficient in consolidated rocks cores during enhanced gas recovery by CO2 injection. Journal of Natural Gas Science and Engineering, 60, 190-201. https://doi.org/10.1016/j.jngse.2018.10.007

Connate water salinity is a vital property of the reservoir and its influence on the displacement efficiency cannot be overemphasised. Despite the numerous analytical literatures on the dispersion behaviour of CO2 in CH4 at different parametric condi...

Stabilizing biopolymers in water-based drilling fluids at high temperature using antioxidants, a formate salt, and polyglycol (2018)
Journal Article
Akpan, E., Enyi, G., Nasr, G., & Yahaya, A. (2018). Stabilizing biopolymers in water-based drilling fluids at high temperature using antioxidants, a formate salt, and polyglycol. Journal of Engineering Technology, 7(2), 469-486

Biopolymers degrade in water-based drilling fluids when exposed to high temperatures for some time, thus leading to hole-cleaning problems such as stuck pipe. To stabilise biopolymers in drilling fluids, the mechanisms by which they degrade at elevat...

Introduction – Industry operators are becoming more critical of synthetic surfactants for various oil and gas operations. Principal among these concerns is the environmental degradation. As a result, there is increasing interest in the use of biosurf... Read More about Physicochemical characterization of sodium surfactin for oil and gas industry application.

Experimental investigation of methane-water and methane-brine IFT measurements using pendant drop (rising bubble) method (2018)
Journal Article
Yahaya, A., Akpan, E., Enyi, G., Nasr, G., & Abbas, A. (2018). Experimental investigation of methane-water and methane-brine IFT measurements using pendant drop (rising bubble) method. Journal of Engineering Technology, 6(1), 394-407

Gas hydrate formation involves low molecular gas mass transfer to a cage-like structure formed by water molecule under low temperature and high-pressure conditions. Gas hydrate is considered a problem if it develops along a pipeline. In order to solv...
