Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This causes project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates...

The oil companies are concerned to replace the petroleum reserves they produce in order to maintain their future level of activity. Booked reserves also represent an important input when analysts value these companies. Many producer countries want to control their own resources, a goal which can...

Drilling expenses has increased sharply in recent years. Average meters drilled per day significantly influences exploration costs. Hence it is important to understand the factors that determine meter per day. In this study we analyse the effect of drilling depth on meter per day. There are...

We examine drivers of cost overruns in Norwegian development projects in the oil and gas sector. The multivariate longitudinal econometric analysis employs a unique and detailed dataset consisting of 80 different projects between 2000 and 2015. Among the significant results, we find that the...

In this paper we analyse rig rate formation of floaters operating on the Norwegian Continental Shelf. We first develop a simple bargaining model for rig markets. Then we examine empirically the most important drivers for rig rate formation in the period 1991q4 to 2013q4. We use reduced form time...
