for technical and economic success of miscible gas injection projects, an accurate laboratory measurement of minimum miscibility pressure (mmp) at reservoir conditions is essential. on the other hand, compositional reservoir simulator is a useful tool in gas injection studies and prediction of mmp. the main goal of this paper is to describe a procedure to generate a three phase sequential type ...

On the basis of a qualitative study three different operational oil and gas petrochemical sites, in Middle East, Asia-Pacific Europe, we examine how actors construe error prevention ...

As the North Eastern town of Middlesbrough was trying on for size a new robe as ‘Digital City’ fitted to re-generate the impoverished industrial underwear, while the skinny ribs of petrochemical and steel still poked out the sky a proposal was made: Some personal and humanist space in the digital fabric of a virtual architectural model. We planned to appropriate a town-planning model and experi...

Identification and selection of Six Sigma projects are one of the most frequently discussed issues in the Six Sigma literatures today. In this paper a two-stage methodology has been proposed based on (i) Real Option Analysis for evaluating the value of the project to improve the managerial flexibility (ii) a zero–one integer linear programming model for selecting and scheduling an optimal proje...

The most important aim of every project is on time completion, budget consideration and reaching the highest possible quality, based on contract. This paper suggests a methodology for risk management in engineering, procurement, and construction (EPC) projects. Risk management enables project teams to perform with minimum deviation from predetermined goals. The proposed methodology identifies a...

the scheduling problems are the non-polynomial problems-hard (np-hard), is to solve it, and meta-heuristic innovative method compared with the exact method require less time and memory.in this research, developed imperialistic competitive algorithm used to solving the single-mode resource-constrained project scheduling problem.also the basic feasible solution algorithm used in order to increase...

Hydrogen Sulfide. Hydrogen sulfide (H2S) is a colorless gas with a characteristic odor of rotten eggs. It naturally occurs in the gases from volcanoes, sulfur springs, undersea vents, swamps, stagnant bodies of water, and in crude petroleum and natural gas. Additionally, bacteria, fungi, and actinomycetes release hydrogen sulfide during the decomposition of sulfur-containing proteins and by the...

Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]

The oil industry needs solid and reliable materials in almost all processes. By making nano-scale materials, lighter, more robust, and more robust equipment than today's products can be produced. Nanotechnology in the field of oil industry and its related industries, in addition to reducing the environmental hazards of this sector and the possibility of saving from harvesting of underground res...
