Pseudo 3D seismic using kriging interpolation

Abstract

Seismic method is one of geophysical method that is used to determine subsurface condition of the earth. There are two types of seismic data, 2D seismic and 3D seismic. The advantages of using 3D seismic data is it has less uncertainty for imaging the earth subsurface. However, the cost to acquire 3D data is higher than producing 2D data, thus some company needs to invest more money to be able to get a better data quality. One of the ways to have 3D seismic data without having to spend a lot of money is by creating a 3D pseudo seismic data from 2D seismic data. The purpose of this research is to create a 3D pseudo seismic data by using a geostatistical method. The geostatistical method that is used in this research is Kriging interpolation. By the help of Petrel software, kriging interpolation is done to create the 3D seismic. The pseudo 3D seismic results show a good image such as difference in amplitude, also structural geology features of subsurface. In conclusion, the use of kriging interpolation in pseudo 3D seismic still needs more work and development so the results will be good for the next interpretation steps.
