Enhanced gas recovery by nitrogen injection : the effects of injection velocity during natural gas displacement in consolidated rocks (2020)
Journal Article
Mohammed, N., Abbas, A., Enyi, G., Edem, D., & Suleiman, S. (2020). Enhanced gas recovery by nitrogen injection : the effects of injection velocity during natural gas displacement in consolidated rocks. Journal of Natural Gas Science and Engineering, 83, 103513. https://doi.org/10.1016/j.jngse.2020.103513

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...

Alternating N2 gas injection as a potential technique for enhanced gas recovery and CO2 storage in consolidated rocks : an experimental study (2020)
Journal Article
Mohammed, N., Abbas, A., Enyi, G., Suleiman, S., Edem, D., & Abba, M. (2020). Alternating N2 gas injection as a potential technique for enhanced gas recovery and CO2 storage in consolidated rocks : an experimental study. Journal of Petroleum Exploration and Production Technologies, 10(8), 3883-3903. https://doi.org/10.1007/s13202-020-00935-z

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...

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.
