Abstract

Abstract: Several studies have developed costs of monitoring; however the costs are typically applied to generic sites and use a set of pre-selected monitoring approaches. In this study we use analytical models of leakage cases to assess the cost of leakage detection for sites with specified properties and assess the value of different monitoring approaches. We assume that leakage occurs at former production wells that have been plugged and abandoned (P&A). We compare pressure-based monitoring (PBM) and geochemical-based monitoring (GBM) techniques under the same economic constraints and to increase the spatial monitoring coverage. Then the project economics using probable correctness model provides estimates of the number of required PBM and GBM wells and their coverage ratio according to a defined annual budget. It was concluded that PBM technique has a better coverage over P&A wells than GBM technique and therefore is more cost-efficient.
