The international oil companies (IOCs) in Nigeria have expressed concern over the federal government’s intention to change the laws governing the oil and gas industry including the fiscal terms. They claim that the proposed fiscal terms will affect their bottom line and trigger uncertainties in their investments in the upstream sector. Therefore, this research was conducted with the aim of eval...

in this article, modeling and optimization of power consumption of two–stage compressed airsystem has been investigated. to do so, the two – stage compressed air cycle with intercooler offajr petroleum company was considered. this cycle includes two centrifugal compressors, ashell, and a tube intercooler. for modeling of power consumption, actual compressors isentropicefficiencies and intercool...

The health risk resulting from benzene exposure in petroleum refineries was calculated using data from the scientific literature from various countries throughout the world. The exposure data was collated into four scenarios from petroleum refinery environments and plotted as cumulative probability distributions (CPD) plots. Health risk was evaluated for each scenario using the Hazard Quotient ...

This paper presents the design of adaptive load-shedding strategy by executing the artificial neural network (ANN) and transient stability analysis for an Industrial cogeneration facility. To prepare the training data set for ANN, the transient stability analysis has been p...

This paper proposes a data-driven approach in determining an optimal inspection interval for a petroleum pipeline system. The approach accounts for the determination of both the probability of failure and its associated consequences. The probability of failure is estimated by fitting the historical data of failure of the pipeline into either a homogenous Poisson process or non-homogenous Poisso...

This paper presents the definition and implementation of a CORBA-based system for the distributed monitoring of automated oil wells located in on-shore petroleum fields. Conducted by the automation of industrial processes in the oil and gas area, the development of computational distributed systems, based on emerging middleware technologies and designed to monitor and actuate in such particular...

A method is described for extracting the petroleum from petroleum-bearing ̄uid inclusions hosted in the diagenetic cements of sedimentary rocks, whilst minimising contamination from petroleum in the pore space. A clean-up technique, involving the addition of extraction standards to the rock prior to analysis, has been developed that allows increased con®dence that the hydrocarbons extracted are...

Unexpected price spikes in petroleum can lead to instability in markets and have a negative economic effect on sectors which rely on petroleum consumption. Sudden rises in the price of petroleum do not have to be long-term to cause negative, cascading impacts across the economy. Firms which make futures purchases or hedge against a higher price during a price spike can become insolvent when the...
