Abstract Molecular dynamic simulations have been performed to study the effect of electrolyte concentrations and temperature on the structural, dynamic, and thermal properties of cationic surfactants at the water/n-decane interface. Results show that optimal salinity (where the interfacial tension (IFT) passes through a minimum) could be reached for erucylbis-(hydroxyethyl)-methylammonium chloride (EHAC). In contrast, the IFT of cetyltrimethylammonium chloride (CTAC) solution increased for all N...

The mechanism of pitting corrosion of carbon steel by an oilfield microbial consortium was investigated using a combination of X-ray micro-computed tomography (µCT), surface analytical techniques and DNA/RNA-based 16S sequencing. The most active microorganisms in biofilms were Thermoanaerobacter sp., a type of fermentative, thiosulphate-reducing bacteria. µCT allowed the identification of corrosion products phases as well as their volume percent and surface area at each corrosion layer. µCT reve...

CO2 injection into geological reservoirs is considered as a promising technology to improve oil recovery from oil reservoirs and to reduce greenhouse gas emissions. However, due to the density difference between the injected CO2 and formation brine, the injected CO2 tends to move vertically towards the surface. The risk of this vertical CO2 movement can be prevented by four different trapping mechanisms (i.e. structural, residual, dissolution, and mineral trapping). From the dissolution of CO2 i...

Abstract Use of thermodynamic hydrate inhibitors (THIs) for prevention of gas hydrate formation in the oil and gas field operations is a well-known and accepted process all over the world. Although glycols are reported as THIs, but only monoethylene glycol is studied in detail and applied conventionally. In this study, gas hydrate inhibition efficiency of propylene glycol is determined. The data is acquired using a stirred cryogenic PVT sapphire cell and the hydrate dissociation temperature meas...

Abstract Hypothesis The advanced low salinity aqueous formulations are yet to be validated as an injection fluid for enhanced oil recovery (EOR) from the carbonate reservoirs and CO2 geosequestration. Interaction of various ionic species present in the novel low salinity surfactant nanofluids with scCO2/CO2 saturated aqueous phase interface and at the interface of CO2 saturated aqueous phase/mixed wet (with CO2 and Decane) limestone surface at the conditions of low salinity at reservoir conditio...

Abstract Mono ethylene glycol (MEG) has been used as a thermodynamic hydrate inhibitor in the gas industry. Due to its high usage, recoverability and environmental impact, MEG is regenerated instead of releasing to the environment. During the regeneration (distillation) process, MEG is exposed to higher temperatures in the reboiler to remove surplus water. When exposed to high temperatures, MEG thermal degradation process can occur due to dissociation to organic acids including glycolic, acetic ...
