Following the Brent Spar controversy, the OSPAR countries reached a unanimous agreement in 1998 for the future rules for disposal of petroleum installations. The vast majority of existing offshore installations will be re-used or returned to shore for recycling or disposal. For installations...

High oil prices are normally expected to stimulate exploration and the development of new oil and gas fields. But over the last few years, financial analysts have focused strongly on short-term accounting return (RoACE) for benchmarking and valuation, and this has led to high capital discipline...

This paper investigates the economic value of trade when prices of transportation services are endogenous to cross-market price spreads. This is relevant for liquefied natural gas (LNG) exports. LNG transportation capacity is limited in the short-run, and long lead-times are involved in...

When natural gas prices are subject to periodic decoupling from oil prices, for instance due to peak-load pricing, conventional linear models of price dynamics such as the Vector Error Correction Model (VECM) can lead to erroneous inferences about cointegration relationships, price adjustments...

There is a planning gap for CCS projects in Europe. CCS demonstration plants are not implemented as expected. This fact is at odds with optimistic valuation reports that apply socio-economic valuation criteria for climate projects. However, CCS plants are in most cases to be implemented by...

Socio-economic criteria for climate projects have been used in analysing the value of the climate benefit of a reduction in CO2. These reports are optimistic, yet CCS demonstration plants are not implemented as expected. Little attention has been devoted to profitability assessments based on...

A long period of rig scarcity and high rates has led to innovation in the procurement of rig services and in relationships between oil companies and rig contractors. Discussions have been conducted on joint ventures between companies and contractors, for instance. This paper describes and...

Governments in extraction countries are anxious to estimate expected investment in development projects, since they represent an essential element of the macro economy. The overall level of activity is also crucial to oil companies, since the macro picture affects cost levels, the supplies...

Petroleum administration can be regarded as a principal-agent problem. The government allocates exploration and production rights to petroleum companies on behalf of the population. The government is the principal and the companies are agents. With the aim of capturing revenue for the state, the...

Substantial elements of innovation have been observable during recent years in rig supply, in particular regarding contracts and organisation. This trend has been driven by the fact that rising costs over many years have put profitability under pressure. On the basis of theory and available...
