Journal of petroleum science and engineering [online], 211, article 110018. Available from: https://doi.org/10.1016/j.petrol.2021.110018

The accurate prediction of the fluid dynamics and hydraulics of the axial or helical flow of non-Newtonian drilling fluids in the annuli is essential for the determination and effective management of wellbore pressure during drilling operations. Prev... Read More about The combined effect of fluid rheology, inner pipe rotation and eccentricity on the flow of Newtonian and non-Newtonian fluid through the annuli..

A new approach for quantitative mapping of retention mechanisms of associative polymers in porous media. (2021)
Journal Article
AFOLABI, R.O., OLUYEMI, G.F., OFFICER, S. and UGWU, J.O. 2021. A new approach for quantitative mapping of retention mechanisms of associative polymers in porous media. Journal of molecular liquids [online], 343, article 117685. Available from: https://doi.org/10.1016/j.molliq.2021.117685

The retention of associative polymer molecules poses a significant challenge for its transport in porous media, and this arises due to the hydrophobic interactions that exists between the retained molecules. The known experimental approach in literat... Read More about A new approach for quantitative mapping of retention mechanisms of associative polymers in porous media..

Effect of two-phase gas-liquid flow patterns on cuttings transport efficiency. (2021)
Journal Article
SALUBI, V., MAHON, R., OLUYEMI, G. and OYENEYIN, B. 2022. Effect of two-phase gas-liquid flow patterns on cuttings transport efficiency. Journal of petroleum science and engineering [online], 208(part A), article 109281. Available from: https://doi.org/10.1016/j.petrol.2021.109281

Effective cuttings transport and accurate drilling hydraulics prediction remain issues of concern during drilling operations of horizontal, extended reach and multilateral wells. While several studies have adopted a two- or three-layered modelling ap... Read More about Effect of two-phase gas-liquid flow patterns on cuttings transport efficiency..

Correction to: Swelling performance of sodium polyacrylate and poly(acrylamide‑co‑acrylic acid) potassium salt. (2021)
Journal Article

Experimental investigation of the effect of temperature on two-phase oil-water relative permeability. (2021)
Journal Article
BALOGUN, Y., IYI, D., FAISAL, N., OYENEYIN, B., OLUYEMI, G. and MAHON, R. 2021. Experimental investigation of the effect of temperature on two-phase oil-water relative permeability. Journal of petroleum science and engineering [online], 203, article ID 108645. Available from: https://doi.org/10.1016/j.petrol.2021.108645

Relative permeability is affected by several flow parameters, mainly the operating temperature and fluid viscosity. Fluid viscosities change with temperature, which correspondingly affects the relative permeability. Temperature is believed to have a...
