Natural gas liquids and liquefied petroleum gases have played an important role in the current US shale gas boom. Depressed gas prices in recent years have made pure natural gas operations less profitable. The result is that liquids components in gas production have become increasingly important...

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...

This paper studies how drilling costs are affected by the business cycle. We decompose the major elements in these costs – rig rates and drilling speed – and examine how they interact with variations in oil prices. A highly relevant consideration in the current circumstances is whether oil...

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...

We investigate the potential for statistical forecasting of aggregate oil and gas investment on the Norwegian Continental Shelf (NCS). A unique and detailed dataset containing data from 109 different fields on the NCS between 1970 and 2015 was employed. A set of 1080 autoregressive distributed...

The decline in oil prices, combined with high costs which are slow to deflate, has brought forward the date when some fields on the Norwegian continental shelf (NCS) will cease production. Measures are therefore urgently required to extend the producing life of these fields and to improve their...

Many socio-economic rates of returns for climate projects have been used in analysing the present value of the climate benefit. However, little attention has been devoted to profitability assessments based on commercial considerations. Economic valuation of climate projects, seen from the...

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...
