Crude oil blending is an important unit operation in petroleum refining industry. A good model for the blending system is beneficial for supervision operation, prediction of the export petroleum quality and realizing model-based optimal control. Since the blending cannot follow the ideal mixing rule in practice, we propose a static neural network to approximate the blending properties. By the d...

BACKGROUND Since 1992, physicians have reported work-related diseases among workers in Norway's offshore petroleum industry to the Petroleum Safety Authority, as required by law. AIMS To analyse the number of reported work-related musculoskeletal disorders and risk factors (occupation and reported exposure) from 1992 to 2003. METHODS Data from the Petroleum Safety Authority's registry of wo...

Norway has two major problems. First, an enormous budget surplus, resulting from petroleum exports, which economists say could overheat the Norwegian economy if it were to be reinvested on the Norwegian mainland. Second, the dependence on the petroleum sector for continued economic growth. There is consensus that new industry needs to be developed in order to maintain Norwegians’ standard of li...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

Biosurfactants are a group of microbial molecules identified by their unique capabilities to interact with hydrocarbons. Emulsification and de-emulsification, dispersion, foaming, wetting and coating are some of the numerous surface activities that biosurfactants can achieve when applied within systems such as immiscible liquid/liquid (e.g., oil/water), solid/ liquid (e.g., rock/oil and rock/wa...

Anomaly detection is the problem of finding patterns in data that do not conform to an a priori expected behavior. This is related to the problem in which some samples are distant, in terms of a given metric, from the rest of the dataset, where these anomalous samples are indicated as outliers. Anomaly detection has recently attracted the attention of the research community, because of its rele...

OBJECTIVES To estimate the risk of cancer due to occupational exposure to petroleum products in the Swedish transport and refinery industries. METHODS In a retrospective cohort study the cancer incidence in 4128 men and 191 women, who had worked for at least one year in the petroleum industry, was compared with the incidence in the general population. The job titles and employment times for e...
