Dry Gas Phase properties as fn(P) : Phase Properties (Solvent 0.98 Mole Fraction = 0.0000)įigure 7: Vapor Z factor for Dry gas case. Dry Gas P-T envelope : P-T Diagram 1400įigure 6: 2-Phase P-T diagram for Dry Gas case. The plots for different cases are shown in Figures 6 to 14. Note: You are now able to analyze the results in terms of the criteria for definition of each of the fluid types. Repeat Items 1 to 14 and build a dat file for other types of fluid and save them as ‘wetgas.dat’, ‘gascondensate.dat’, ‘volatileoil.dat’, ‘blackoil.dat’ files respectively and then run. Save the WinProp file as ‘drygas.dat’ and run it 15. The final WinProp interface should look like Figure 5.įigure 5: WinProp interface for modeling Dry Gas case.ġ4. For all the oil cases, add a single-stage separator calculation with separator pressure of 100 psia and separator temperature of 75 F.

Input the reservoir pressure as 250 Psia, pressure step of 250 Psia and No. Input the reservoir temperature as 180 deg F, temperature step as 0 and No. Type in comments as “Phase properties as function of pressure”. This can be done by adding another Two-phase Flash calculation from. Examples of properties which may be plotted are: Zfactors, phase fractions, densities, molecular weights, K-values, etc. pressure at the reservoir temperature using the 2-phase flash calculation. Input the data as shown in Figure 4.įigure 2: Component definition for other fluid typesįigure 3: Two phase flash calculation at standard condition.įigure 4: Input data for two-phase envelop calculation.ġ0. Open the form by double clicking on it and type in “P-T envelope” under the comments section. Insert a “two-phase Envelope” form in the Main WinProp interface. We would also like to generate a pressure-temperature phase diagram. The input value of “saturation pressure estimate” is used as an initial guess by WinProp during the iteration processes for calculating the actual saturation pressure. Also, input the reservoir temperature and saturation pressure estimate as 180 ✯ and 1000 Psia respectively. Under the comments type “Psat at reservoir temperature”. Double click and open the saturation pressure calculation form. Insert “Saturation pressure calculation Form" into the WinProp Interface to perform a saturation pressure calculation at the reservoir temperature. The “two-phase flash calculation form should look like as shown in Figure 3. The feed composition is subjected to mixed i.e. Leave other calculation options as default. We are planning to perform a flash at 14.7 Psia and 60 deg.F. Open this form by double clicking on it and under the comments section type “Standard condition flash”. Insert “two phase flash calculation form" into the WinProp interface. The “secondary” corresponds to the injection fluid (if applicable). Open the "composition form" and input the mole fractions of the primary composition as mentioned in the file: “Five Fluid Types Data.xls”. Your component definition form should look like Figure1 for Dry gas and Figure 2 in case of other fluid types.įigure1: Component definition for case of Dry Gasĥ. Use the properties given in the file: “Five Fluid Types Data.xls”. Click on “options” button in the “component definition form” and select “insert own component” based on specific gravity (SG), boiling point (TB) and molecular weight (MW). In all cases except “Dry Gas” also, characterize the C7 fraction with a single pseudocomponent by inserting a user defined component. Open “component selection” form and insert the library components in the following order: CO2, N2, C1, C2, C3, IC4, NC4, IC5, NC5, and FC6. Select PR 1978 and the equation of state to be used in characterizing the fluid model, select “Psia & deg F” as the units and Feed as mole. 2.ĭouble click on “Titles/EOS/Units” and write “Dry gas/Wet gas/Gas condensate/Volatile oil/Black oil” in the comments and the Title1 section depending on the case you are modelling. Double click on the WinProp icon in the Launcher and open the WinProp interface. Dry gas, wet gas, Gas condensate, volatile oil and Black oil.
