In this study, the oil recovery potential of Smart Water in the Danish sector of the North Sea chalk reservoirs was investigated. A series of flooding experiments were conducted at reservoir conditions, and a spontaneous imbibition test was carried out at reservoir temperature. Reservoir cores were used along with crude oil samples from the North Sea and representative synthetic formation water...

The impact of pre-corrosion on the performance an imidazoline-based corrosion inhibitor was evaluated with respect to inhibition uniform and localised in CO2-environments. Corrosion protection found be a function two factors, adsorption/film formation presence products. This effect most significant continuous FeCO3-rich layer high coverage steel surface, resulting only providing ?25 % overall a...

A program has been developed for generating stability diagrams that concisely represent the thermodynamic state of multicomponent, multiphase aqueous systems in wide ranges of temperature and component concentrations. The diagrams are based on a thermodynamic model that combines the Helgeson-Kirkham-Flowers equation of state for standard-state properties with a solutions nonideality model based...

Concerns over reducing CO2 emissions associated with the burning of fossil fuels in combination with an increase in worldwide energy demands is leading to increased development of renewable energies such as wind. The installation of offshore wind power structures (OWS) is one of the most promising approaches for the production of renewable energy. However, corrosion and fatigue damage in marine...

CO2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. In this study, the lower part of Es1 reservoirs in Pucheng oilfield was introduced as the target reservoir. By studying the minimum miscible pressure in CO2 flooding, the reservoir could achieve miscible flooding. Long core displacement experiments prove...

The low enthalpy program developped in the Paris Basin provides the opportunity for studying the gas geochemistry of the calcareous aquifer of the Dogger. Hydrocarbons and C02 are mainly biogenic, He displays high concentrations. He, Ar and N2 have multiple origins (radioactive decay, atmospheric migration, biochemical processes). The distribution of the gases in the zones of the basin varies i...

Carbonation is among the primary reasons for the initiation of the corrosion of steel rebar in reinforced concrete (RC) structures. Due to structural loading effects and environmental actions, inevitable cracks have frequently occurred in concrete structures since the early ages. Additionally, climate change, which entails increases in CO2 concentration and environmental temperature, will also ...

Amine degradation is the main significant problems in amine-based post-combustion CO2 capture, causes foaming, increase in viscosity, corrosion, fouling as well as environmental issues. Therefore it is very important to develop the most efficient solvent with high thermal and chemical stability. This study investigated thermal degradation of aqueous 30% 2-aminoethylethanolamine (AEEA) using 316...

The effect of cementite morphology on the corrosion layer formation four high-strength carbon steels was studied in an aqueous solution containing CO2 and CO2/H2S. linear polarization resistance weight loss data reveal that as phase fraction is increased, rate increases environment, while no trend observed CO2/H2S environment. results indicate a porous and, non protective forms whereas A mechan...
