The FK Response When Applied It on 2D Seismic Data from Razzak Oil Field, Western Desert, Egypt

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.
