technology development projects, unlike many other kinds of projects don’t have pre-defined goals or clear implementation methods at the beginning of the project. among other uncertainties that any project could have, technology development projects have a high degree of uncertainty in the definition of project. for this reason, conventional project management methods such as those provided in ...

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...

The new requirements for sulfur content in liquid fuels demand the use of novel deep desulfurization processes. 4-methyldibenzothiophene, 4,6dimethyldibenzothiophene and their alkyl-substituted derivatives are the key substances that need to be separated from diesel fuel and fuel oil. These compounds require higher hydrogen consumption in the hydrodesulfurization process and the use of addition...

the welfare policies and programs in the iran had started to establish modern state in iran since 1925.this paper deals with the relation between oil revenues and social welfare in iran before 1978(1357) revolution. why developmental activities within welfare policies and programs couldn’t maintain their stability and continuity? the bureaucrats and redefined groups were became the main target ...

Abstract—This paper evaluates oil displacement by water in Hauterivian sandstone reservoir of Kashkari oil field in North of Afghanistan. The core samples of this oil field were taken out from well No-21st, and the relative permeability and fractional flow are analyzed. Steady state flow laboratory experiments are performed to empirically obtain the fractional flow curves and relative permeabil...

A geological model was built for the Sadi reservoir, located at Halfaya oil field. It is regarded as one of most significant oilfields in Iraq. The study includes several steps, essential which importing well logs from six wells to Interactive Petrophysics software conducting interpretation and analysis calculate petrophysical properties such permeability, porosity, shale volume, water saturati...

A great deal of attention has recently been focused upon "enhanced oil recovery"; that is, the application of recently developed processes for recovering oil that would normally remain in a reservoir following depletion by conventional techniques. Since this heretofore unrecoverable remaining oil amounts to about 300 billion barrels in the U.S. alone (see Figure 1), one can see why enhanced rec...

The cycling of sulfur in oil field brines has focused predominantly on bacteria involved in the reduction of sulfur species to sulfides, which are detrimental to the production of these fields. However, recent interest in the addition of nitrates and nitrites to oil field brines for the remediation and control of sulfides has rekindled new interest in sulfide bio-oxidation. Addition of nitrate ...

An important decision in the development of a mixed oil and natural gas field is whether to produce or re-inject the natural gas. There is a trade-off between the income from the sale of natural gas and the higher oil production obtained from re-injection. We consider the optimal timing problem of when to stop natural gas injection for a set of offshore petroleum fields using a real options app...
