Identification of mechanisms of CO2 oil recovery enhancement and sequestration formation of clathrate hydrates to isolate CO2 from flue gas.
Patents-wipo, a method of locating resources in a reservoir that printable arcadia vouchers includes at least one injection well and at least one production well includes mapping a modeled permeability characteristic of structures making up the reservoir, computing, based on the modeled permeability characteristic, an indicator of flow.Thesaurus: synonyms and related words sweep noun (movement thesaurus: synonyms and related words sweep noun (clean thesaurus: synonyms and related words sweep noun (WIN) a clean sweep a situation in which one player, team, etc.Applying a random walk simulation method, it is found that an efficient sweep can be performed by a blockage mechanism where every invaded throat is blocked upon invasion.Patents-wipo, sweep efficiency is improved by injecting steam or gas such as carbon dioxide until steam or gas breakthrough occurs at the production well (14) after which a mixture including a noncondensible gas and an aqueous surfactant-polypeptide solution is injected into the formation (10).Example sentences with "sweep efficiency translation memory patents-wipo, polyol for improving sweep efficiency in oil reservoirs patents-wipo, the use of a pyruvate-rich xanthan gum is expected to increase the recovery of oil by improving both the oil/water mobility ratio and the sweep efficiency in reservoirs.Patents-wipo, a strategy to monitor the movement of the CO2 flooding front and to predict the fingering phenomenon is used to provide a warning tool to improve the sweep efficiency, according to some embodiments.Patents-wipo, the FPS solution demonstrates a strong interaction with oil and the great potential to increase both volumetric sweep efficiency and microscopic displacement efficiency in EOR.Patents-wipo, proper design of this method gives a vertical sweep efficiency of the gas that is several-fold greater than the best of previous WAG flood designs, especially in thin formations.Although porosity and connate water saturation may vary aerially and vertically within a reservoir, the most important rock.Optimization of gels and gel placement techniques to control CO2 conformance, improving sweep efficiency and thus expanding reservoir storage volume.Volume 158, Pages 664-671 get rights and content, keywords, low salinity water injection (lswi).T US informal to win all the parts of a competition, or to win very easily : The Yankees swept the four-game series with the Blue Jays.Wins everything that is available : Romania made a clean sweep of the medals.Patents-wipo, this rise in pressure due to the injection of the cryogenic fluid increases the reservoir conductivity enhancement and improves sweep efficiency of the flood fluids, which leads to the production of more fluids from to the subterranean reservoirs.Patents-wipo, the use of one or more ionic polyvinyl alcohol copolymers is expected to increase the recovery of oil by improving both the oil/water mobility ratio and the sweep efficiency in reservoirs with a high degree of heterogeneity.Improved estimation of volumetric sweep efficiency.Patents-wipo, the Arcobacter strains grow in the oil reservoir to form plugging biofilms that reduce permeability in areas of subterranean formations thereby increasing sweep efficiency, and thereby enhancing oil recovery.As a consequence of the nonuniform permeabilities, any injected fluid will tend to move through the reservoir with an irregular front.
The vertical sweep efficiency, EV, is defined as the fraction of the vertical section of the pay zone that is the injection fluid.
