Περίληψη | Two different methods are used for solving the phase behavior problem during reservoir simulation applied
to hydrocarbon reservoirs; the black oil Tables and the compositional approaches. The black oil Tables
simulators use Tables of volumetric factors (solution gas-oil ratio, oil formation volume factor, gas
formation volume factor, oil content) versus pressure and by performing interpolation at each pressure
step the produced volumes are calculated. On the other hand, the compositional simulators, perform the
phase behavior calculations by using an equation of state so as to calculate the equilibrium phases and
their properties at different operating conditions.
The main advantages of the black-oil Tables simulators are that they require low calculation (CPU) time low
computer memory. On the other hand, compositional simulators are more accurate and can perform better
with volatile oils and gas condensates. Nevertheless, operators still use black-oil simulators to simulate
volatile oils and gas condensates, valuing thus more the speed of calculations as the expense of accuracy. The
question is how much information is lost with respect to the compositional approach and how much off the
black oil tables approach reservoir simulation predictions can be.
For this thesis, the commercial software IMEX and GEM of Computer Modeling Group has been used.
These models are presented in detail and the different options that they offer are discussed. The objective of
this work was to discuss to present the available models of the black oil tables and compositional simulators
as well as their difference in predictions and to assess their differences in predicting the reservoir production
performance. A simple reservoir containing volatile oil was modeled and its depletion was simulated using
both simulators and their results were compared.
The two simulators exhibited a small divergence between their predictions for the initial volumes in place
and the simulation runs. However, the compositional simulator is thought to be more accurate than the black
oil simulator in its predictions as it is a compositional simulator. Moreover, it was found that the black oil
simulator calculated almost the same amount of initial volumes in place, whereas it over-predicted the oil
recovery and the oil cumulative production. | en |
