Recently, Rune Likvern wrote a post talking about the possibility of a natural gas shortage in the United Kingdom, possibly as soon as February or March 2009. Rune isn't the only one worried about the supply of gas in Europe and the UK. A little over a year ago, Euan Mearns wrote two posts about the European natural gas supply, the first called European Natural Gas and a follow-up addendum called Daddy, will the lights be on at Christmas? In this post, we combine the two posts and re-run them. Besides being relevant to the gas shortage issue, the posts also provide some additional background related to current Russian/Ukrainian dispute.

OECD European gas production looks set to peak in 2008. After that, falling production combined with rising demand will see OECD European gas imports wanting to rise from current 197 BCM per annum to 442 BCM per annum by 2020. Where will this gas come from and how will rising European imports affect N America and the rest of the world?

According to the IEA World Energy Outlook 2008, p. 261:

Output of natural gas liquids — light hydrocarbons that exist in liquid form underground and that are produced together with natural gas and recovered in separation facilities or processing plants — is expected to grow rapidly over the Outlook period. Global NGL production is projected to almost double, from 10.5 mb/d in 2007 to just under 20 mb/d in 2030.

One can see from IEA's chart of World Oil Production by Source that the growth of natural gas liquids, or NGLs, is being depended on as a significant contributor to total world oil production:

One way of estimating expected NGLs is as a ratio to natural gas production, representing the wetness or dryness of gas. One would expect this ratio to decline over time, based on what normally has been observed from fields, areas and regions with good quality data. Instead, the IEA is forecasting that this ratio will increase in the future.

In this analysis, Samuel Foucher (“Khebab”) and I (Tony Eriksen or “ace”) present an update of Wikipedia Megaprojects data. We also provide forecasts of future oil production, reflecting the Megaprojects data. The IEA uses megaprojects in its analysis and we reconcile our Megaprojects information to the data they provide in their report.

A wide variety of methods can be used to forecast future oil production. Each will provide different indications. Sam and I each make projections with megaprojects data, using somewhat different methods. Sam’s projections are shown in Figure 6. My forecasts are shown in Figures 8, 9, and 10. Despite our differing methods, the indications we produce are all substantially lower than the indications of the IEA.

Until quality data about production history, reserves and future development plans including capacities are obtained for fields in secretive OPEC countries, forecasts beyond 2012 are highly uncertain, regardless of the source. While quality data remain unavailable, the world's future energy security, in particular liquid fuels supply security, remains an extremely high risk.

This chart shows the IEA WEO 2008 forecast together with Sam's forecast derived from using Megaprojects sanctioned capacities and yet to be sanctioned capacities (including yet to find oil - YTF). By 2020, the IEA's forecast is significantly greater than Sam's forecast.
