Long-chain alkanes are a major component of crude oil and therefore potentially good indicators of hydrocarbon spills. Here we present a set of new bacterial bioreporters and assays that allow to detect long-chain alkanes. These reporters are based on the regulatory protein AlkS and the alkB1 promoter from Alcanivorax borkumensis SK2, a widespread alkane degrader in marine habitats. Escherichia...

This paper reports on an oil/retail petrol supply chain which was undergoing a Business Process Reengineering (BPR) exercise. The paper models and analyses the effect of information sharing on the performance parameters (inventory costs and bullwhip effect) of an actual Serbian oil industry supply chain. The main idea is to show through business process modelling how the BPR of existing process...

In recent years, hydraulic fracturing and horizontal drilling have been applied to extract crude oil from tight reservoirs, including the Bakken formation. There is growing interest in understanding the greenhouse gas (GHG) emissions associated with the development of tight oil. We conducted a life cycle assessment of Bakken crude using data from operations throughout the supply chain, includin...

World wide crude transportation is the central logistics operation that links the upstream and downstream functions and plays a crucial role in the global supply chain management in the oil industry. In this work, we develop a decision support system to investigate and improve the combined inventory and transportation system in a representative world-wide crude supply problem. The decision supp...

a r t i c l e i n f o A large part of government revenues in Russia comes from royalties and export taxes on crude oil, oil products, and gas. Recently, the Russian government has considered reducing export taxes on crude oil and oil products compensated by an increase in the royalty on crude oil. The objective of the paper is to analyse the economy-wide effects of this proposal. Moreover, a hy...

Soil bacterial population dynamics were examined in several crude-oil-contaminated soils to identify those organisms associated with alkane degradation and to assess patterns in microbial response across disparate soils. Seven soil types obtained from six geographically distinct areas of the United States (Arizona, Oregon, Indiana, Virginia, Oklahoma, and Montana) were used in controlled contam...

Ozonation with a subsequent biodegradation treatment was performed to remove recalcitrant organic compounds from long-term weathered crude oil contaminated soil. Samples were analyzed by GC/MS and column chromatography to monitor changes in crude oil composition. A functional gene array was used to examine microbial community dynamics. After a 6h ozonation treatment with a constant concentratio...

One of the major uses of management games is as a learning tool to improve decisions made under dynamic uncertainty. This paper presents a web-based gaming mode simulation model of a supply chain concerning the procurement and supply of oil. The game mirrors the traditional oil supply chain consisting of Refineries, Storage Points, Depots and Retail Outlets. The computer controls the decisions ...
