WitrynaFirst video in our Visual Reservoir Series where we take a look at immiscible gas injection. Footage is sped up to six times actual speed. WitrynaImmiscible gas injection requires in situ oil to be greater than 40 °API, below which immiscible gas injection cannot make the oil mobile enough and miscible gas injection should be adopted. Since two distinct phases exist in immiscible flooding, fingering and channeling, similar to water flooding, could occur.

Witryna11 kwi 2024 · However, regardless of the injected pore volume, when the methane content in the injection gas reached 40%, the flow changed from miscible to immiscible. It indicates that the injection gas has an optimum composition range in the initial periods of the process, which leads to maximum recovery while reducing costs … Witryna23 lis 2024 · The gas used for injection is typically hydrocarbon based, but carbon dioxide (CO 2) and nitrogen (or nitrogen-rich flue gas) can also be used. The injected gas can be miscible, gas and oil dissolve in each other to form a more mobile liquid, or it could be immiscible, where oil and gas remain in their respective phases.

Witryna26 kwi 2024 · Immiscible gas injection is usually classified as either crestal or pattern, depending on the location of the gas injection wells. The same physical principles of oil displacement apply to either type of operation; however, the overall objectives, type of field selected, and analytical procedures for predicting reservoir performance vary ... 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.
