Miscible Gas Injection

Summary In reservoir simulations, it is common practice to use a limited number of components to describe the reservoir fluids, ranging from 2 (black-oil models) to 5-12 [compositional equation-of-state (EOS) based models]. On the opposite, surface models usually require a greater number of components, typically from 15 to 30. The hydrocarbon components used in surface models are usually lumped into pseudocomponents in reservoir simulations. This disparity in the description of the mixture may become an issue whenever integrated asset models are developed, with the aim of linking surface process and reservoir engineering. In this paper we implemented a consistent integrated simulation workflow from reservoir to process. Process models with detailed compositional formulation were linked to compositionally simpler reservoir models, using Leibovic's delumping scheme (Leibovic et al. 1996, 2000) to convert fluid composition between EOSs with different component numbers. The proposed workflow was applied to simulate two different recovery processes, namely a gas injection below the dewpoint in a sour gas/condensate reservoir; and a miscible gas injection in a near-critical volatile oil reservoir. Results of this implementation, in which detailed components are traced in reservoir model, are compared to integrated simulations in which all stages are modeled using detailed composition.
