Sand failure: effect of biocide on the geomechanical properties of outcrop carbonate rock under static condition. (2020)
Journal Article
WUYEP, E., OLUYEMI, G., YATES, K. and AKISANYA, A.R. 2020. Sand failure: effect of biocide on the geomechanical properties of outcrop carbonate rock under static condition. Arabian journal of geosciences [online], 13(23), article ID 1239. Available from: https://doi.org/10.1007/s12517-020-06176-y

The effects of chemical interaction of a biocide with formation rocks on the rock geomechanical properties are examined. A combination of analytical tests (Scanning Electron Microscopy/Energy-Dispersive X-Ray Analysis, X-Ray Powder Diffraction and Pa...

A holistic approach to assessment of value of information (VOI) with fuzzy data and decision criteria. (2020)
Journal Article
VILELA, M., OLUYEMI, G. and PETROVSKI, A. 2020. A holistic approach to assessment of value of information (VOI) with fuzzy data and decision criteria. Decision making: applications in management and engineering [online], 3(2), pages 97-118. Available from: https://doi.org/10.31181/dmame2003097v

Classical decision and value of information theories have been applied in the oil and gas industry from the 1960s with partial success. In this research, we identify that the classical theory of value of information has weaknesses related with optima...

Developing a novel mechanistic model for four-phase oil-water-gas-sand stratified flow in a horizontal pipe. (2020)
Thesis
MORADI, B. 2020. Developing a novel mechanistic model for four-phase oil-water-gas-sand stratified flow in a horizontal pipe. Robert Gordon University, PhD thesis. Hosted on OpenAIR [online]. Available from: https://openair.rgu.ac.uk

Presence of sand and solid particles in untreated petroleum sometime is inevitable. Although many techniques have been developed to prevent sand particles from entering the pipeline, such as downhole gravel packs, these downhole sand control devices...

Determination of a critical separation concentration for associative polymers in porous media based on quantification of dilute and semi-dilute concentration regimes. (2020)
Journal Article
AFOLABI, R.O., OLUYEMI, G.F., OFFICER, S. and UGWU, J.O. 2020. Determination of a critical separation concentration for associative polymers in porous media based on quantification of dilute and semi-dilute concentration regimes. Journal of molecular liquids [online], 317, article ID 114142. Available from: https://doi.org/10.1016/j.molliq.2020.114142

Hydrophobic interactions are an inherent property of associative polymers which results in the formation of molecular aggregates. The loss of hydrophobic interactions under reservoir conditions have been reported, and this results in increased fluid...

Sensitivity analysis applied to fuzzy inference on the value of information in the oil and gas industry. (2020)
Journal Article
VILELA, M., OLUYEMI, G. and PETROVSKI, A. 2020. Sensitivity analysis applied to fuzzy inference on the value of information in the oil and gas industry. International journal of applied decision sciences [online], 13(3), pages 344-362. Available from: https://doi.org/10.1504/IJADS.2020.10026404

Value of information is a widely accepted methodology for evaluating the need to acquire new data in the oil and gas industry. In the conventional approach to estimating the value of information, the outcomes of a project assessment relate to the dec...
