The most important contributors to the world's total oil production are the giant oil fields. Using a comprehensive database of giant oil field production, the average decline rates of the world's giant oil fields are estimated. Separating subclasses was necessary, since there are large differences between land and offshore fields, as well as between(More)
Two of the most fundamental concepts in the current debate about future oil supply are oilfield decline rates and depletion rates. These concepts are related, but not identical. This paper clarifies the definitions of these concepts, summarizes the underlying theory and empirically estimates decline and depletion rates for different categories of oilfield.(More)
Norwegian oil and gas fields are relatively new and of high quality, which has led, during recent decades, to very high profitability both financially and in terms of energy production. One useful measure for profitability is Energy Return on Investment, EROI. Our analysis shows that EROI for Norwegian petroleum production ranged from 44:1 in the early(More)
Under pressure toward carbon emission reduction and air protection, China has accelerated energy restructuring by greatly improving the supply and consumption of natural gas in recent years. However, several issues with the sustainable development of the natural gas industry in China still need in-depth discussion. Therefore, based on the fundamental ideas(More)
Postprint This is the accepted version of a paper published in Energy. This paper has been peer-reviewed but does not include the final publisher proof-corrections or journal pagination. Chinese coal supply and future production outlooks. Access to the published version may require subscription. Abstract The energy supply of China is completely dominated by(More)
Current world capacity of hydrocarbon liquefaction is around 400,000 barrels per day, providing a marginal share of the global liquid fuel supply. This study performs a broad review of technical, economic, environmental and supply chain issues related to coal-to-liquids (CTL) and gas-to-liquids (GTL). We find three issues predominate. First, significant(More)
Anthropogenic global warming caused by CO 2 emissions is strongly and fundamentally linked to future energy production. The Special Report on Emission Scenarios (SRES) from 2000 contains 40 scenarios for future fossil fuel production and is used by the IPCC to assess future climate change. Previous scenarios were withdrawn after exaggerating one or several(More)
China's current national policies promote high levels of economic growth, transforming China into a " world factory " , but at a high cost in terms of energy and the environment. At the same time, this growth and transformation also forms the backbone of China's economy, underpinning social stability. China faces a dilemma to reconcile its economy, energy(More)
