Oil Investment in the North Sea
Investment in the United Kingdom Continental Shelf (UKCS) involves three separate but highly interrelated activities: exploration, development and production. The exploration and extraction decisions were analysed recently by Pesaran (1 990) and Favero (1 990). The aim of this paper is to provide a model of the investment decision in the UKCS, where the development process is explicitly modelle...
متن کاملDistribution of thermophilic marine sulfate reducers in north sea oil field waters and oil reservoirs.
The distribution of thermophilic marine sulfate reducers in produced oil reservoir waters from the Gullfaks oil field in the Norwegian sector of the North Sea was investigated by using enrichment cultures and genus-specific fluorescent antibodies produced against the genera Archaeoglobus, Desulfotomaculum, and Thermodesulforhabdus. The thermophilic marine sulfate reducers in this environment co...
متن کاملDiet among oil-workers on off-shore oil installations in the Norwegian sector of the North Sea.

Two hundred and three persons were interviewed about what they had eaten the previous 24 h. Food purchased for the installations in the previous 5 months was recorded. Results based on 24 h recalls showed that average daily intake of energy was 12.2 MJ of which 17% came fro...
متن کاملStabilisation/solidification of Synthetic North Sea Drill Cuttings Containing Oil and Chloride
On the UK Continental Shelf, up to 80,000 tonnes wet weight of oily drill cuttings are produced annually. These are heterogeneous wastes generated from the petroleum drilling industry, composed of significant percentages of hydrocarbons, heavy metals and chlorides. Since 1992, the discharge of drill cuttings containing more than 1% oil-on-cuttings has been prohibited. Moreover, the extensive in...
متن کاملMarine biosurfactants, I. Screening for biosurfactants among crude oil degrading marine microorganisms from the North Sea.
Three bacterial strains of marine origin were isolated during a screening for biosurfactants among n-alkane degrading microorganisms. One strain-identified as Alcaligenes sp. MM1-produced a novel glucose lipid. In the case of Arthrobacter sp. EK 1 the well-known trehalose tetraester was found as major component. From another pure culture classified as Arthrobacter sp. SI 1, extracellular emulsi...
