A study into the mapping of an induced fracture in a fine grained sediment in biaxial and triaxial stress formations
Thesis
Penketh, S. (in press). A study into the mapping of an induced fracture in a fine grained sediment in biaxial and triaxial stress formations. (Thesis). University of Salford

Unconventional hydrocarbon extraction has increased in the last twenty years due to the post-industrial west needing to increase energy security. This has meant tapping into hydrocarbon resources that are trapped within impermeable sediments. Shale...

Experimental investigation of interfacial tension in two-phase system involving methane and water
Thesis
Yahaya, A. (in press). Experimental investigation of interfacial tension in two-phase system involving methane and water. (Thesis). University of Salford

The understanding of the physical properties of reservoir fluids such as viscous and interfacial forces is critical in many oil and gas, petrochemical, and other related industries. In oil and gas industry, the production, transportation and processi... Read More about Experimental investigation of interfacial tension in two-phase system involving methane and water.

Role of connate water salinity in gas dispersion during enhanced gas recovery by carbon dioxide injection and sequestration
Thesis
Abba, M. (in press). Role of connate water salinity in gas dispersion during enhanced gas recovery by carbon dioxide injection and sequestration. (Thesis). University of Salford

A better understanding of the factors that influence mixing between CO2 and CH4 in natural
gas reservoirs can provide an avenue to minimise the gas dispersion during Enhanced Gas
Recovery (EGR). This highlights EGR’s field scale adoption as a poten... Read More about Role of connate water salinity in gas dispersion during enhanced gas recovery by carbon dioxide injection and sequestration.

Removal of scales in petroleum production tubing utilising high pressure atomisers
Presentation / Conference
Enyi, G., Nasr, G., Nourian, A., El Kamkhi, M., & Burby, M. Removal of scales in petroleum production tubing utilising high pressure atomisers. Presented at ICLASS 2012, 12th Triennial International Conference on Liquid Atomization and Spray Systems, Heidelberg, Germany

Scale is a mineral deposit usually formed on surfaces in contact with water. Scale deposition in petroleum
production wells can be attributed to mixing of incompatible waters, changes in thermodynamic, kinetic and
hydrodynamic conditions in oilfiel... Read More about Removal of scales in petroleum production tubing utilising high pressure atomisers.
