    The aim of Master thesis is interpretation of Vertical Seismic Profiling in Duża Wólka region. The survey was made in well S-421A, which is located in south-east part of the foresudetic monocline, on the outskirts of Duża Wólka village. Data processing was realized in the Vista 5.1 software. The effects of processing are VSP stack (near offset) and VSPCDP stack (far offset). The results correlated to well logs and stratigraphic profile were used for seismic horizons identification.

    A regional 2D seismic survey Obrzycko-Zabartowo was conducted earlier indicated an existence of a salt dome in the beginning of a line. This area is located in north-western part of Poland known for its salt tectonics connected with Zechstein salt layers. Based on part of the survey, a well located nearby and available geologic information a simplified 2D model of that area was designed in OMNI 3D Design software and interval velocities and densities were estimated. A series of analyses on model were performed. Next, with success, a simulations of 2D survey acquisitions with synthetic records were performed and processed in VISTA software to determine optimal parameters for surveying this area.

    Ocena efektywności transformacji Radona w systemie Vista

    The main goal of seismic data processing is to reach the highest signal/noise ratio possible. Various types of noise tend to contaminate the registered wave field of which linear coherent events are the most persistent. Ground roll is a high-amplitude, low-frequency linear wavetrain travelling near the surface of the earth, capable of obscuring genuine reflections. A range of procedures is routinely applied to attenuate it of which the main emphasis was put on the Radon transform. A set of tests in the Vista processing software has been carried out in order to assess the effectiveness of three types of the transform (linear, parabolic and hyperbolic). The results were compared with those of some traditional approaches to ground roll removal. Hyperbolic Radon transform turned out to be the most effective.
