“An Experimental Study of Bulk Foam Properties with Commercial Surfactants in Saline Environments”
(Master thesis, 2019-06-22)Foam is a fascinating two-phase phenomenon with a wide range of different industrial applications; contaminated-aquifer remediation, separation of waste-waters, enhanced oil recovery, gas leakage prevention and matrix-acidizing ... -
Diatom frustules as a biomaterial: effects of chemical treatment on organic material removal and mechanical properties in cleaned frustules from two Coscinodiscus species
(Peer reviewed; Journal article, 2016-08)The three-dimensional structure of silica diatom frustules offers a great potential as nanoporous material for several nanotechnological applications, but the starting point for these applications is the ability to obtain ... -
Effect of different surfactant structures on the brine-crude oil and brine-alkane interface in different aqueous environments.
(Master thesis, 2017-06-16)In producing oil fields, both the production rate and ultimate recovery from the field can be enhanced by injection of chemicals into the reservoir formation. To optimise the commercial benefits, it is important to understand ... -
Low Salinity Waterflood in Combination with Surfactant/Polymer: Effect of Brine Composition
(Master thesis, 2014-06-02)The effect of low salinity water (LSW) on enhanced oil recovery has been known for decades. Although much research is done on the topic, a general agreement of the prevailing mechanism for the low salinity effect has still ... -
Simulation Studies of Hybrid EOR
(Master thesis, 2019-06-22)Injection of low salinity brine in combination with surfactant and polymer for enhanced oil recovery (EOR) have been proven to substantially increase oil recovery. Large EOR potential exists on the biggest fields on the ... -
Solubilization of medium-chained alcohols in some ENORDET O series surfactants
(Master thesis, 2013-10-23)Primary to tertiary pentanol and -hexanol in Shell Chemicals' ENORDET O series IOS 1923, and for primary pentanol in IOS 2024, have been investigated by a thermodynamic approach. Standard partial molar volume and isentropic ... -
A strategy for low cost, effective surfactant injection
(Peer reviewed; Journal article, 2014-05)Ideally, in a chemical flooding process, one would like to inject a surfactant solution that has good solubility at the relevant conditions, ultralow interfacial tension (efficient oil mobilisation) and low loss of surfactant ...
