Determination of concentrations of sulfur compounds in different petroleum samples is a true analytical challenge. Only analytical procedures based on gas chromatography can meet the sensitivity and accuracy requirements dictated by up-to-date petroleum industry. The objective of this work is to develop the method for the quantifying of sulfur compounds in petroleum hydrocarbon streams. The opt...

Artificial neural networks are rapidly gaining popularity. This paper discusses the importance of this new tool to petroleum engineers, and the advantages that this computing process has over other conventional methods. The mechanics by which neural networks achieve their objective are also discussed. Artificial neural networks can assist petroleum engineers in solving some fundamental petroleu...

The petroleum activities on the Norwegian Continental Shelf are subject to regulations issued by the Norwegian Petroleum Directorate. One important issue in these regulations is the use of acceptance criteria, and this paper discusses some philosophical aspects of acceptance criteria for risk, and the role of statistical decision theory within safety management. Statistical decision theory has ...

Phenol formaldehyde (PF) resins are widely used as wood adhesives in the industrial production of exterior-grade plywood panels, oriented strand board panels and particleboards due to their superior performance including high bonding strength, heat resistance, excellent water resistance and chemical stability1. However, phenol, one raw material for the synthesis of PF resins, is a petroleum-bas...

Software Interoperability for Petroleum Applications — In this introduction to the thematic dossier on software interoperability, we emphasise the key role of software for the petroleum industry, and we give market and technical motivations for interoperability. This is followed by a brief overview of the technologies used in the search for interoperability and by a summary of the five technica...

There have been several recent studies of the Japanese oil industry, but they have all focused on the impact of the abolition of the Tokusekiho, the Provisional Law relating to the Importation of Specified Petroleum Products, that restricted the importation of specified petroleum products to limited number of companies. The Tokusekiho, was abolished at the end of March 1996. However, despite th...
