Gas/Oil Sample Clauses

Gas/Oil. The partitioning coefficient for a gas/oil tracer is defined as K = CT2 T CT (4.6) 8 and the phase concentration for the tracer is computed using the tracer material balance equation as CTA = C8ACT8 + C2 AC T2 where CT8 CT2 = CT C8 + C2 KT = KT CT C8 + C 2 KT A = 2 and 4 (4.7) where C8, C2 are the overall concentrations for gas and oil species. UTCHEM has the capability of modeling gas/oil tracer partitioning coefficients as a function of reservoir temperature. Partitioning coefficient for tracers as a function of temperature is given by a linear function as: KTi = KTi , ref [1 + TKi (T − Tref )] for tracer i (4.8) where the temperatures are in •F and KTi , ref is the partitioning coefficient of tracer i at reference temperature (Tref) and TKi is a constant input parameter in (•F)-1.
