Water Alternating Gas Injection
- Start date: 2011

- Topic: Pore-scale simulations and theoretical upscaling of two- and three-phase flows in natural porous media for enhanced oil recovery through water alternating gas injection.
The project aims at the development of a flexible and modular modeling tool for the effective design and implementation of Water Alternating Gas (WAG) technologies for Enhanced Oil Recovery (EOR). Key objectives include: (i) laboratory-scale activity and development of protocols and data sets for two- and three-phase relative permeability acquisitions performed at the Eni laboratory facilities; (ii) testing of the semi-empirical sigmoid-based model for (three-phase) oil relative permeability on laboratory-scale data; (iii) field scale testing and application of the semi-empirical sigmoid-based model for oil relative permeability under three-phase flow; (iv) extension of two-phase theoretical and computational tools to three-dimensional complex pore spaces of real rock images; (v) development of an ability to generate controlled synthetic replicates of three-dimensional rock images to be employed in the quantification of the uncertainty associated with two-phase relative permeabilities due to the random structure of the pore space; (vi) setting of applicable algorithms for upscaled three-phase relative permeabilities.
