Application of the PROMETHEE and VIKOR methods for selecting the most suitable carbon dioxide geological storage option

Abstract

CO₂ storage in geological formations is one of the leading solutions for mitigation greenhouse gas emissions. Types of geological formations that can be used for CO₂ storage, that are discussed in this paper are: depleted oil and gas reservoirs, saline aquifers and injection CO₂ in partially depleted oil reservoirs for enhanced oil recovery (ЕОР–CO₂ method).  In order to select the most suitable geological storage of CO₂, the ranking of these storage options was performed using two models of multi criteria analysis, PROMETHEE and VIKOR.

In this paper are presented an overview of considered criteria (storage capacity, total storage costs, risk assessment costs, storage time dynamics, risk of CO₂ leakage from geological formation and risk of CO₂ leakage through the well), description of applied multi criteria analysis methods, selection of optimal CO₂ storage option and results of their application.
