Screening CO2 storage options in The Netherlands

This paper describes the development and application of a methodology to screen and rank Dutch reservoirs suitable for long-term large scale CO2 storage The screening focuses on off- and on-shore individual aquifers. gas and oil fields In total 176 storage reservoirs have been taken into consideration 138 gas fields, 4 oil fields and 34 aquifers, with a total theoretical storage potential of about 3200 Mt CO2 The reservoirs are screened according to three criteria potential storage capacity, storage costs and effort needed to manage risk Due to the large number of reservoirs, which limits the possibility to use any pair-wise comparison method (e g Multi-Criteria programs such as Bosda or Naiade), a spreadsheet tool was designed to provide an assessment of each of the criteria through an evaluation of the fields present in the database and a set of scores provided by a (inter)national panel of experts The assessment is sufficiently simple and allows others to review it, re-do it or expand it The results of the methodology show that plausible comparisons of prospective sites with limited characterization data are possible (C) 2009 Elsevier Ltd All rights reserved
