EN Seismic reflection is the most significant method in hydrocarbon prospecting which uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves (Ashcroft 2011). Accurate interpretation of reflection seismic data is one of the most important elements of a successful oil and gas exploration program. Proper interpretation of seismic data requires an understanding of the subsurface formations and how they may affect wave reception. To do this seismic modeling is done. Seismic modeling is a topic for which approximations pay a critical role. Seismic modeling is done to investigate the expected seismic response from a given subsurface model (Kasina 1998). In this paper author presents the application of seismic 1D and 2D modelling for interpretation of the 107-2-96K profile, recorded in Strachocina gas field. Seismogeological models were made using borehole data and the geological sections. Theoretical seismic sections were computed with the Tesseral software (Hinds & Kuzminski 2002). A geological identification of seismic horizons was made on the basis of synthetic seismograms calculated for the borehole Strachocina-45. ID synthetic seismograms are formed by simply convolving an embedded waveform with a reflectivity function (Yilmaz 2001). For clear identification of faults and correlation of seismic horizons with geological ones 2D seismic modeling was prepared. Seismogeological model and calculation of theoretical seismic sections were made in Tesseral software (Hinds & Kuzminski 2002). The results of seismic modeling used in geological interpretations enabled the reconstruction of gas horizons and allowed for more reliable identification of faults.
