Immiscible gas injection
WitrynaSummary Gas injection into the oil reservoirs is one of the effective methods of increasing oil recovery. The gas injection into the reservoirs when it is fully or partially miscible with oil is a difficult physical process from the point of view of mathematical modelling. The simulation of miscible gas injection process by the simulator could … Witryna7 lis 2016 · Five immiscible gas injection pilots (GIPs) including the SWAG pilot were initiated in late 2001 in this reservoir to assess the benefits of immiscible gas injection in improving oil recovery. This paper describes the performance analysis from field surveillance data of the SWAG pilot which is also aided by a sector simulation model ...

Witryna18 wrz 2024 · The result of immiscible injection has been a lowering of the gas-oil contact, a thinning of the oil column, and leaving a remaining oil saturation in the gas cap of up to 40 percent.
Witryna12 cze 2015 · Miscible injection is a proven, economically viable process that significantly increases oil recovery from many different types of reservoirs. Most miscible flooding projects use CO 2 or nitrogen as solvents to increase oil recovery, but other injectants are sometimes used. This page provides an overview of the fundamental … Witryna10 cze 2013 · In this paper, a single matrix block surrounded by fractures is used to study the performance of a fractured gas condensate system in natural depletion, miscible and immiscible gas injection. C 1, N 2, CO 2 and stock-tank gas composition are considered as injection gases and their miscibility with condensate is studied. Also …
Witryna1.11.3 Gas Injection. This technique includes miscible injection of different gases such as carbon dioxide, nitrogen, flue, and natural gas. The objective of miscible injection is to improve oil displacement and reservoir pressure maintenance by forming a single phase between the injected gas and oil. Witryna9 lip 2024 · Gas flooding in reservoirs is a well-known secondary recovery mechanism and also a gas storage method in the world (Bybee 2001; Azin et al. 2008; Mohammadi et al. 2011; Yuncong et al. 2014; Agrawal et al. 2016; Kumar et al. 2024).Comprehensive analysis of miscible/immiscible gas injection has been undertaken by many …
Witryna29 mar 2024 · The CO2 is compressed above a threshold pressure, called minimum miscibility pressure (which depends on the oil composition and the reservoir temperature) point before injection. This technique is mostly applied after primary recovery mechanisms and waterflooding has been exhausted. About 5-20% [1] of the original …
