Scale-up of miscible flood processes

Scale-up of miscible flood processes. Annual report

“…2.11 shows these K-values versus elution time from the GC. (It was shown in a previous report [52] that K-values correlate much better with elution time than with carbon number. )…”

“…The next step is to use the Peng-Robinson EOS to perform a flash calculation for a mixture of Means stock tank oil a_ld 80 mele % C02 at 90°F and 1000 psia, conditions at which experimental data had been obtained previously [52,71]. The results of this flash--the K-values and liquid phase mole fraction of each componentmare given in Table 2.10.…”

“…2.13 shows the chemical type distribution for Means crude oil, the oil that was used in the partitioning experiments. These data were compared to other Permian Basin oils in last year's report [52]. The composition of the Means oil was found to be quite similar to them, except that Means has a slightly larger fraction of normal alkanes in the intermediate range (C12 to C30).…”

“…The GC/MS equipment and operating conditions were described previously [52], as were the data analysis procedures for both phase samples and whole oils. Phase samples for the partitioning data were obtained from the PVT system described previously [71].…”

“…In the interests of conciseness, we rely on the detailed descriptions given previously of experimental equipment, mathematical methods, and numerical techniques [51,52] and focus on new results. Significant progress has been made in severaJ areas.…”
