Abstract: The Razzak oil field is located, together with several other oil fields, along the Qattara - Alamein Ridge in the north Western Desert of Egypt. This ridge comprises the main hydrocarbon producers in the Alamein Basin, with several closed structures, which are in a favorable geological setting with respect to hydrocarbon prospectively. Razzak field was discovered in March, 1972 it is producing from four different horizons, Abu Roash "G" (AR/G), Bahariya, Aptian Dolomite, and Alam EL Bueib BA-1 marker [3]''. The seismic data processing is the important step to get rid of the unwanted data. (noise data) by applying different flows, so that we can get enhancement of the signal to noise ratio. There are many steps applied on data, one of these steps is FK filter which is a double edged weapon step it may be destroyed all signal and hidden the reflectors, or enhanced the signal by removed the noise especially linear noise. For that we must be carefully when applied FK filter process on seismic data to avoid occur distortion on data and consequence missing interpretation. In this paper showing the heavy effective of FK filter on seismic data in Razzak oil field when applied it, and display the result obtained. We applied FK filter with two different cutting techniques in four different processing flows to show its effect on seismic data. The seismic data used in this paper is represented 2D seismic line in Razzak field it is Razaak 18- 87 in SEG Y format. Vista software is used to accomplish seismic processing flows which applying on it.

Abstract: As the demand for distributed power supply increases, the permanent magnet generator with many advantages has been widely used. In order to overcome the defect that the permanent magnet generator can't maintain the output voltage constantly by adjusting the excitation current the same as with the electrically excited synchronous generator, this paper presents the stabilized control strategy based on speed-adjusting of prime mover, that is use the rectified DC voltage as feedback through adjusting the speed of the prime mover to achieve no static error control. This paper introduces the control principle of the power generation technology, based on the research of the external characteristics of permanent magnet generator and operating characteristics of the prime mover analysis of the feasibility of this control method. The curve of the prime mover's speed varies with load obtained by co-simulation when maintaining the generator's output voltage constantly. The control strategy proposed in this paper is the organic combination of the prime mover and generator, which simplifies the control the structure of generator set. This power generation technology is suitable for the distributed power supply spontaneous for personal use. The stabilization of DC voltage can avoid the requirement of constant frequency and the stable DC power supply can supply the power for DC load or through the inverter for AC load.

Abstract: Due to water is contained in the natural gas, also some other substance can form into hydrate in some special conditions. Above zero degree natural gas is a solid-state unstable compound. It can not only bring about the blockage of the pipe, but also cause the blockage of the spray nozzle and the separation equipment. So we use method of absorption to dehydrate. In this method we use triethylene glycol (TEG) as a sorbent. Because the TEG has a strong dehydrated capability of natural gas, and also TEG is quiet stable under high temperature, so TEG can not be solidified, at the same time TEG is easy to be regenerated. During the process of carrying, the losing amount of TEG is acceptable, and the dew point is high. All the property decide the TEG is suit for dehydrate. The absorbtion tower have many advantages. First, it is easy made and investment is low and pressure can be maintained long enough so that it can save power. Second, it can be used continuously. Third, the volume of tower is easy to be expanded. forth, the equipment of the tower is easy to be assembled so that it can lower the complexity of construction. Finally, it is convenient to avoid the pollution of solid adsorbent. In this method, the working theory of the dehydration tower is briefly stated. The paper not only make an reasonable choose of the parts of absorbtion tower, but also check the stress on the body of the absorbtion tower. What’s more, the way to reinforce the holes of the tower and technical demands of the tower are also explained in the paper.

Abstract: Logs normalization is an indispensable and basic work for coal-bed methane（Abbreviated as CBM）logging interpretation, and also the key step to realize interpretation from single well to multi-well. B block’s DEN and GR logs come from different time periods and different logging companies. In order to finish the following CBM logging interpretation and lithofacies interpretation, type well plus histogram method is selected to finish DEN and GR logs normalization according to the applicable conditions of different normalization methods and B block actual situation. Type well plus histogram normalization methods can reduce the influence of man-made factors of the CBM logs from the actual application, distribution of logs after normalization are more consistent, which would lay the solid foundation of the following CBM development work.

Abstract: In the present study the usability of simarouba biodiesel blends in air cooled diesel engineand performance optimization of engine is intended in terms of percentage blend and Brake Power (BP). An air cooled diesel engine of 4.4 kW rated power running at constant speed of 1,500 rpm is chosen for conducting the experiments. Experiments are conducted with diesel and biodiesel blends (10%, 20% and 30% by volume) at different load conditions. The performance parameters like Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumptions (BSFC) and emissions-Carbon Monoxide (CO), Hydro Carbon (HC), Oxides of Nitrogen (NOX), and Filter Smoke Number (FSN) are analyzed.The performance of engine is slightly improved in terms of marginal improvement in BTE and BSFC with 20% biodiesel blend as compared to diesel. Emissions are considerably reduced with all blends compared to diesel. The performance optimization of engine is performed using desirability approach of Response Surface Method (RSM). Statistical models correlating percentage biodiesel blend, BPand responses (BTE, BSFC, CO, HC, NOX, and FSN) are developed.
