TNO Monitoring Plan Development Tool

Abstract

TNO has developed a software tool that supports the design of a risk-based monitoring plan for a CO2 storage site. The purpose of the tool is to aid storage site operators by facilitating a structured monitoring technologies selection or evaluation process. The tool makes a selection this recommended monitoring technologies, based on a set of rules that link a monitoring technology to a particular risk factor or regulatory requirement. In our paper we describe conceptual framework of the tool and its functionality. The starting point of the tool is the selection of site-specific characteristics and scenarios which contain risk factors referred to as FEPs (Features, Events, and Processes). These FEPs are matched with monitoring technologies that fulfill a set of pre-specified requirements, for instance, related to performance criteria or operational costs. The tool is built around two databases: one consisting of risk factors and associated parameters and another one containing monitoring technologies and the information they provide. The database with the risk factors is the product of a TNO risk assessment methodology (CASSIF). The user-defined inputs for the monitoring plan development tool are site-specific characteristics and the scenarios which contain risk factors. Site characteristics are for instance the type of storage reservoir or the storage site location (e.g. on-shore or offshore). The individual risk factors in each scenario are then translated into measurement parameters, which are subsequently matched with the monitoring technologies. Additional information about the monitoring technologies can be displayed, depending on user preferences and requirements.
