Abstract
An equation state with a mixing rule that captures a multi-component layering within nanopores may be used to model (1) fluid mixture in the nanopores of the reservoir and (2) movement of fluid between the nanopores and large pores of the reservoir. Such modeling of fluid behavior in large pores and nanopores of the reservoir may enable more accurate simulation of the reservoir (e.g., for hydrocarbon recovery).
Claims20
A system for modeling fluid behavior in a reservoir, the system comprising:
- one or more physical processors configured by machine-readable instructions to:
- obtain reservoir characteristic information, the reservoir characteristic information defining characteristics of a reservoir;
- determine an initial condition of the reservoir based on the reservoir characteristic information, the initial condition of the reservoir including initial condition of fluid inside large pores and nanopores of the reservoir;
- model fluid movement between the large pores and the nanopores of the reservoir using an equation of state to simulate changes from the initial condition of the reservoir, wherein a mixing rule for the equation of state captures a multi-component layering to model fluid mixture in the nanopores of the reservoir;
- and
- facilitate simulation of fluid extraction from the reservoir based on the fluid movement between the large pores and the nanopores of the reservoir.
