TL;DR: In this article, the authors used surface cleaning methods typically prescribed in the surface chemistry community and found that the water contact angle θ on a clean quartz substrate is low, 0-30°, and that θ increases with pressure.

TL;DR: In this paper, the pore-scale arrangement of CO 2 droplets in three carbonates and two sandstones is shown to obey power law distributions with exponents consistent with percolation theory over two orders of magnitude.

TL;DR: In this paper, the authors reviewed the state-of-the-art of comprehensive applications of aqueous amines, ionic liquids (ILs) and binding organic liquids (BOLs) for natural gas sweetening and health/environmental impacts of amine, ILs and BOLs.

TL;DR: In this paper, the authors used molecular potential energy surface diagrams of the deprotonation of a protonated amine (AmineH + ) in combination with ion speciation plots of the vapour liquid equilibrium (VLE) model to provide a better understanding of the drastic reduction of energy required for CO 2 stripping from some amine solutions under certain operating conditions.

TL;DR: In this paper, a field-scale design optimization of coupled CO 2 -EOR and storage operations from the viewpoint of oilfield operators is presented. But the results quantitatively describe the relations between the design parameters, reservoir properties, asset size, and the economic parameters.

TL;DR: In this paper, a capillary flow model using invasion percolation physics that accurately matches the plume's geometry is presented, which enables an estimate of the shale barrier behavior and caprock performance.

TL;DR: In this paper, the authors extend the previous studies on the geomechanical modeling of fault responses during underground carbon dioxide injection, focusing on the short-term integrity of the sealing caprock and hence on the potential for leakage of either brine or CO 2 to reach the shallow groundwater aquifers during active injection.

TL;DR: In this paper, the authors used residual saturation trapping, the immobilisation of isolated micro-bubbles of CO2 in reservoir pores, to determine the fraction of injected CO2 that will remain trapped in the reservoir, even if a leakage event were to occur.

TL;DR: The accepted and refereed manuscript to the article as discussed by the authors is locked until 2016-07-26 and is available to the reader until 2017-08-26.Copyright 2014 Elsevier Ltd.

TL;DR: In this paper, the absorption kinetics of carbon dioxide (CO 2 ) into amino acid promoted potassium carbonate (K 2 CO 3 ) solutions have been studied using a wetted-wall column.

TL;DR: In this article, a thorough review of patent database and open literature has been carried out in order to be as exhaustive as possible, and the individual process modifications are analyzed and then generalized into “elementary” modification groups.

TL;DR: In this paper, the authors used quantitative mineralogical data and δ13C, δ18O and F14C isotopic data to quantify the amount of CO2 fixation and identify carbon sources.

TL;DR: In this paper, the authors describe potential impacts to groundwater quality due to CO2 and brine leakage, discuss an approach to calculate thresholds under which no impact to groundwater occurs, describe the time scale for impact on groundwater, and discuss the probability of detecting a groundwater plume should leakage occur.

TL;DR: In this paper, the Axisymmetric Drop Shape Analysis with no-Apex (ADSA-NA) method was used to measure the density of CO2, interfacial tension between CO2-rich and aqueous phases and wettability of reservoir rock and caprock in contact with these fluids at reservoir conditions.

TL;DR: In this article, the DEEA/2M MAPA mixture was tested in the Gloshaugen (NTNU/SINTEF) pilot plant and the experimental pilot campaign was validated toward a simulation model implemented in our in-house code CO2SIM.

TL;DR: In this paper, a 30-year injection of cold liquid CO2 into the underground storage formation was studied and the impacts on the rock mechanical stability during a 30 year injection period.

TL;DR: In this paper, the influence of nanoparticles on the CO2 absorption by MEA and MDEA in the bubbling reactor was investigated, and it was found that the enhancement factor increased with the increase of the solid loading of nanoparticle up to a maximum value and then decreased.

TL;DR: In this paper, an experimental investigation of hysteresis in residual trapping and relative permeability of CO2 in a CO2/water system at 50°C and 9MPa in a Berea sandstone core was conducted.

TL;DR: In this article, a cost model is developed for CO2 pipeline transport, which starts with the physical properties of CO2 transport and includes different kinds of steel grades and up-to-date material and con- struction costs.

TL;DR: In this paper, the authors describe numerical modeling that is able to reproduce the experimental results of drying of brine-saturated sandstone cores by gas injection in the laboratory and the evolution of water and gas saturation profiles and precipitation of salt inside the samples are followed with injection time.

TL;DR: In this paper, an extended pulsed neutron-gamma (PNG) saturation model for NaCl-brines is developed and applied to a time-lapse PNG monitoring data set from the Ketzin site.

TL;DR: In this paper, the authors evaluated the reboiler heat required for solvent regeneration and CO 2 recovery for AMP/PZ and MEA as both a function of CO 2 -lean loading at a similar liquid to gas (L/G) ratio, and as a function for L/G ratio at a different CO 2-lean loading.

TL;DR: A carbon nanotube reinforced polyvinyl amine/polyvinyl alcohol (PVAm/PVA) blend nanocomposite membrane with facilitated transport fixed-site-carriers (FSC) for CO 2 /CH 4 separation was developed with the focus on improving membrane separation performance at elevated pressures and the challenges related to the up-scaling of the membrane for potential industrial applications as discussed by the authors.

TL;DR: In this paper, a series of experiments using muscovite as a representative of common aluminosilicate minerals were conducted to identify several possible causes of the ambiguity problem in contact angle (CA) measurements.
