We review the rigorous efforts presented in the literature to implement carbon capture, utilization, and storage (CCUS) projects, in the context of technological challenges, capacities, and perspectives. We categorize...

... of the CO 2 flood indicated good sweep was taking place in one lobe. Concerns about the possibility of early breakthrough of CO 2 in the dominate lobe, leaving stranded oil in the other lobe, prompted the initiation of a dedicated injection program. Early breakthrough could lead to filling up our...

... Abstract Injection of solvents (hydrocarbons in liquid and gas form or CO 2 and their combinations) is an alternative method for heavy and extra heavy-oil recovery where thermal methods cannot be applied, like in thin reservoirs, wormholed reservoir after-CHOPS (cold heavy-oil production...

....  With deteriorating water flood economics, over 1.7 billion barrels of remaining oil are left to be targeted by CO 2 flood.   CO 2 floods were successfully developed in a few Frio Fields.  The current (on 1/1/2020) combined cumulative oil production from the Oyster Bayou and the West Hastings CO 2 floods is over...

..., and improve upon the development of this technology. Between initial gas injection and the year 2000, approximately 1 TCF of CO 2 had been injected into the Canyon Reef reservoir. While multiple pilot programs from this time period reported incremental response following CO 2 injection, many...

... with proper fluid description. In general, CO 2 and Hydrocarbon gases are the most common gases used for (or screened for) gas injection processes and due to recent focus to screen for the coupling of CO 2 -sequestration and CO 2 -EOR projects. As CO 2 -Oil phase behavior is quite different than...

... a stable foam with carbon dioxide (CO 2 ), which could be due to the presence of low pH environment in CO 2 floods, relatively high solubility of CO 2 in water, and CO 2 permeability through liquid films. To improve the performance of CO 2 floods, it is imperative to identify surfactants that can...

... allowable iterations is 50. More details on StoSAG optimization algorithm can be found in the work of Chen (2017) . Abstract CO 2 storage through CO 2 enhanced oil recovery (EOR) is considered as one of the technologies to help promote larger scale deployment of CO 2 storage because of associated...

Abstract The primary objective of this work was to investigate the results and the possible mechanisms of oil recovery in a huff-n-puff style improved oil recovery (IOR) field pilot using nanoparticle assisted CO 2 injection. A secondary objective was to study the sensitivity of the process to injection...

During optimization, the NPV is calculated by a machine learning (ML) proxy model trained to accurately approximate the NPV that would be calculated from...

... Abstract Modified in situ CO 2 generation was explored as an improved tool to deliver CO 2 indirectly to the target liquid rich shale formations. Once injected, the special CO 2 - generating compound, urea, decomposes deep in fractures at the elevated temperature conditions, and releases...

... Abstract EOR projects implemented in Bakken and Changqing tight formations demonstrated that the fractures could cause early breakthrough of the injected CO 2 and finally led to undesirable oil recovery. Therefore, conformance control technologies should be developed for the outstanding EOR...
