Thesis
SALUBI, V. 2022. Cuttings transport and hydraulics optimisation for underbalanced drilling (UBD) operations in concentric and eccentric, directional and extended reach wells. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1893048

Underbalanced drilling facilitates the effective control of wellbore pressures - amongst several other important advantages - when compared to conventional drilling technology. However, this involves the flow of multiphase fluids, which introduces ad...

Sand production due to chemical-rock interaction: a review. (2022)
Journal Article
PERETOMODE, E., OLUYEMI, G. and FAISAL, N.H. 2022. Sand production due to chemical-rock interaction: a review. Engineering failure analysis [online], 142, article 106745. Available from: https://doi.org/10.1016/j.engfailanal.2022.106745

Oilfield chemicals are utilized in treating reservoir formations, wellbore completions, wellbore drilling, and to enhance reservoir productivity, which exerts pressure on the formation. Pressure from these processes cause the formation rock to weaken... Read More about Sand production due to chemical-rock interaction: a review..

Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli. (2022)
Thesis
MAHON, R. 2022. Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://doi.org/10.48526/rgu-wt-1880278

Although understanding the relationship between gas-liquid two-phase fluid flows and the effects of the major drilling variables is critical to optimising underbalanced drilling (UBD) operations, to date, this has been an area of limited research and...

Oilfield chemical-formation interaction and the effects on petrophysical properties: a review. (2022)
Journal Article
PERETOMODE, E., OLUYEMI, G. and FAISAL, N.H. 2022. Oilfield chemical-formation interaction and the effects on petrophysical properties: a review. Arabian journal of geosciences [online], 15(13), article 1223. Available from: https://doi.org/10.1007/s12517-022-10469-9

Oil and gas recovery may cause formation damage during drilling, completion, and production phases. As a result of fundamental chemical, thermal, mechanical, and biological interactions, formation damage can occur due to impairment of permeability an...
