NFR CLIMIT Project nr. 176004/I30 Deliverable D1.1 Compilation of estimation procedures for discrete leak paths related to CO2 geological storage

Abstract

The ultimate objective of this project is to contribute directly to establishing necessary confidence that the CO2 in specific geological storage sites will be effectively retained for a time scale of thousands of years. This project will address the specific needs of 3rd party independent verification of geologic storage sites.\rThis document focuses on Sub Project 1 (SP1): Focused procedures for evaluation of the leak potential of discrete leak paths.\rTasks in Work package 1.1: Compilation of estimation procedures for discrete leak paths: Literature review, Develop calculation procedures. \rThe emphasis will be on the ability to map and describe discrete leakage paths before they can be represented in integrated simulation models.\rThis document aims to describe in detail the procedures to be applied by a verifier of a potential CO2 geologic storage site as related to identifying all discrete leakage pathways, including all relevant faults, fractures, thief zones and wellbores, as well as their key characteristics, in order to judge to which extent that these might compromise the storage containment requirements of the site.
