Application of genetic algorithm to hydrocarbon resource estimation

April 2011

  Resource estimation is a process by which the economically recoverable hydrocarbons (HC) in place within a reservoir are calculated. The parameter that goes into resource estimation is variable and contains some aspect of risks. Resource can be defined as the total volume of hydrocarbon in place, which is further classified as reserve when proved commercially viable. Reserve estimation can be carried out...

Methods of water saturation estimation: Historical perspective

March 2011

  One of the most important tasks in reservoir engineering is characterizing different parameters of the reservoir. Water saturation is a parameter which helps evaluating the volume of hydrocarbon in reservoirs. Determination of this parameter started from 1942 by integrating some well logs in clean sandstones. After that, many scientists introduced some equations to validate this procedure in shaly sands and...

Use of exhaust gas recirculation (EGR) and cyclonic separator for simultaneous NOx and PM reduction in DI diesel engines

March 2011

  This study presents the results of exhaust gas recirculation (EGR) and cyclonic separator for simultaneous oxides of nitrogen (NOx) and particulate matter (PM) reduction in a direct injection (DI) diesel engine under different engine loads and speeds. There is a significant NOx reduction by EGR, but PM is hugely increased, especially at high EGR rate-high load conditions. A significant reduction in PM is...

A comparative study of recycling of used lubrication Oils using distillation, acid and activated charcoal with clay methods

February 2011

  Lubricating oils are viscous liquids used for lubricating moving part of engines and machines. Since lubricating oils are obtained from petroleum – a finite product, and with dwindling production from world oil reserves, the need arises more than ever, to recycle used lubricating oils. Accordingly, this research effort focuses on comparative study of four methods of recycling of used lubrication oils:...

Application of Nonlinear Reduction Techniques in Chemical Process Modeling

January 2011

    Model reduction techniques have been used widely in all engineering fields especially in electrical, mechanical as well as chemical engineering. The basic idea of reduction technique is to replace the original system with much smaller state space dimension. A reduced order model is more beneficial to process and industrial field in terms of control purposes by using proper orthogonal decomposition...

Hydromagnetic forced flow between a rotating disc and a naturally permeable stationary porous disc saturated with fluid

January 2011

  This paper considers the flow of a conducting viscous incompressible fluid between two non-conducting parallel discs, when the magnetic field was applied perpendicularly to the discs. The upper disc is in steady rotation, while the lower one is a stationary porous disc. The whole flow is divided into two regions: the free fluid region (between two parallel discs) and the porous region (this flow is of porous...

Chemical method for monitoring demulsification in oil industry

December 2010

  A special and fast chemical method to detect and determine water separation from emulsified crude with accuracy (>97%) was developed. The method was applied successfully to determine the total amount of water in crude and its derivatives. Most methods available for the detection and estimation of low concentrations of water require either sophisticated equipment and/or take a long time. Chemical method...

Optimum site selection of natural gas vehicles station in Bangkok using geographic information system

December 2010

  This paper is to demonstrate the integration of spatial modeling and geographic information systems (GIS) can be used in the optimal site location for natural gas vehicles (NGV) station in Bangkok. Integration has been proposed as one of the characteristics which distinguish GIS from other information systems. Variables used as input in this process mainly address direct construction costs and station...

Optimization of plug utilized in lost circulation treatment while drilling

November 2010

  The major problem of oil wells drilling is circulation lost that can occur near weak formations and before well cementing. Conventional methods such as lost circulation material pills, cement plugs and dual injection were used to combat different types of massive mud loss in spite of their small success rate and high cost and risk. A different circulation treatment has been introduced to optimize plugging of...

A new method for determining the formation temperature from bottom-hole temperature logs

March 2010

  Earlier, the authors proposed a new method for prediction of formation temperatures in permafrost regions from temperature logs in deep wells, and developed working formulas to process field data. The application of the proposed method on predicting the undisturbed formation temperature does not depend: (a) on the well drilling history (vertical depth versus time and stops in mud circulation), (b)...

A prediction to the best artificial lift method selection on the basis of TOPSIS model

March 2010

  Artificial lift as a system adding energy to the fluid column in a wellbore to initiate and enhance production from the well is necessary when reservoir drives do not sustain acceptable rates or cause fluids to flow at all in some cases which use a range of operating principles, including pumping and gas lifting. Technique for order preference by similarity to ideal solution (TOPSIS) model or method is one of...
