A second method is the centrifuge method, which is generally used to obtain capillary pressure and relative permeability information simultaneously. Research experience, report writing and presentation techniques through a team project. More information. The term is most often applied to liquids but applies also to solids and gases. In organic compoundsthe weight percent of hydrocarbon chain often determines the compound's miscibility with water. Miscible injection methods. Theory of emulsion and foam.

  • Multiple Contact Miscibility Processes: Condensing Gas Drive. and therefore these components do not condense out of the gas into the oil. Multiple Contact Miscibility Processes: Vaporizing Gas Drive. In the vaporizing gas drive, the injected fluid is generally a relatively lean gas that. development appears to have been phased: solution gas drive has been initiated . Gas injection EOR methods: miscible and immiscible petroleum and nitrogen; . when there are strict anti-flaring laws to abide by, if there is no viable export route .

    In the FAWAG process foam is used to shut off gas routes and increase .
    At low oil saturations, the region of most interest, the capillary end effect is the greatest. The straight-chain carboxylic acids up to butanoic acid with four carbon atoms are miscible with water, pentanoic acid with five carbons is partly soluble and hexanoic acid with six is practically insoluble.

    When formation dip aids gravity, as illustrated in Fig. Regarding the fluid density difference, gas is always considerably "lighter" than the oil; hence, gas, when flowing, will segregate by gravity to the top of the reservoir or zone and oil will "sink" simultaneously to the bottom of the reservoir or zone.

    Displacements that take place at very unfavorable mobility ratios are unstable, and viscous fingering occurs.

    1. Zoloshura:

      For simple calculations, the mobility ratio is calculated at the endpoint relative permeability values for the two phases.

    2. Maum:

      Gases at reservoir conditions have densities generally one-third or less than that of oil. At low oil saturations, the region of most interest, the capillary end effect is the greatest.
