...Xianwu Jing; Li Zhou; Youquan Liu; Yingying Xu; Wenjian Yin Summary Climate change has brought enormous adverse outcomes to biological activities around the world. The main reason is that too much CO 2 has been released into the atmosphere. In recent years, storing CO 2 in the form of CO 2 hydrate...

... severe in projects that use the injection of reactive fluids into the reservoir, as is the case with carbon dioxide-water alternating gas (CO 2 -WAG) injection. To avoid such an occurrence, scale inhibitors are used, which are continuously dosed at various points in the production flow, from subsea...

...Lionel Ribeiro; Ashley Thoma; Jason Bryant; Desikan Sundararajan; Wesley Zurovec Summary The paper introduces the results of the first CO 2 fracturing campaign conducted in the Williston Basin. From 2015 to 2019, 11 horizontal multistage wells were safely stimulated using a CO 2 -hybrid design...

.... CaCO 3 ‐scale deposit is caused by a shift toward carbonate in the carbonate/bicarbonate/CO 2 equilibrium. When equilibrium shifts in the other direction, the precipitation goes back into solution. In a chemical reaction, chemical equilibrium is the state in which both reactants and products...

... was not satisfactory. Seeking an effective method of heavy‐oil exploitation, the multiple thermal‐fluid stimulation was proposed and studied, in which hot water or steam mixed with carbon dioxide (CO 2 ) and nitrogen (N 2 ) would be injected into the formation for heating the oil and improving heavy‐oil production...

...Wei Chen; Yu Zhou; Weigang Yu; Leilei Yang Summary In this study, shale samples were heated under inert and noninert environments to increase the permeability of the shale. The nanoscale pore structure changes under combustion and pyrolysis [air, nitrogen (N 2 ), carbon dioxide (CO 2 ), and argon...

..., the main GHGs emitted from drilling, production, purification, transport, and storage are CH 4 and CO 2 . According to characteristics of the production, the GHG emissions could be divided into direct source (gas–fueled emissions and flaring) and indirect source (fugitive emissions) ( Table 2 ). Burnt...

...Hamdi Mnasri; Taoufik Wassar; Matthew A. Franchek; Egidio (Ed) Marotta Summary In this work we expand on the carbon dioxide (CO 2 ) corrosion–rate model presented by DeWaard et al. (1995) using a parameter–varying (PV) approach to improve prediction accuracy. Specifically, the constant coefficients...

...Jalil Ghobadi; David Ramirez; Shooka Khoramfar; Robert E. Jerman; Michele Crane; Olufemi Oladosu Summary Separation of carbon dioxide (CO 2 ) from methane (CH 4 ) using a gas/liquid membrane‐contacting system is a promising alternative to conventional absorption techniques, such as wet scrubbers...

...Abdukarem Amhamed; Ahmed Abotaleb Summary In this work we aim to enhance the sour‐gas loading in acid‐gas removal (AGR) systems, maximizing oil‐production rate at the tertiary phase and enhanced oil recovery (EOR), and mitigating vented carbon dioxide (CO 2 ) with minimal modification...

...Giulia Ness; K. S. Sorbie Summary Carbonate and sulfide scales are directly coupled together and differ from other inorganic scales because they are intimately linked to the in-situ concentrations of carbon dioxide (CO 2 ) and hydrogen sulfide (H 2 S), which influence the local pH and availability...
