Approximate distribution of acoustic pseudo-impedance can be obtained from calculation of inversion of the seismic section. That data of the acoustic resistance distribution are the base to image creation and visual interpretation of surrounding rock morphology. That method is useful for lithology-phacial changes detection in case that the changes have response in acoustic resistance changes. In practice, high-level noise signal in coexistence with useful one, make interpretation difficult, if not even impossible. In the paper are suggested some methods of image analysis and processing to inhance the acoustic impedance image feature visualization. That is the way to increase image interpretation credibility in process of lithology-phacial change detection in salt deposits.

Safety and reliability of energy system are one of the most important issues in dynamic development of states and unions (EU). Rock salt deposits with homogeneous inner structure and horizontal or semi-horizontal layering may be excellent sites for localisation of underground hydrocarbon reservoirs. Calculations of seismic section inversion leads to approximation of distribution of acoustic impedance. Data of that acoustic impedance distribution are the basis for image generation and visual interpretation of rock formation structure. Detection of inhomogeneity of lithology-phacial structure of seam-like salt deposits may be recognised on the basis of proper image interpretation of acoustic pseudoimpedance section. In the paper, authors propose context and adaptive transformation of images as a way of increasing effectiveness of image interpretation simulated by INWERS system The paper introduces the algorithm of visual transformation and analysis of results to define quality of rock section structure interpretation. The paper presents the author's suggestion regarding necessity of setting up a gauge of used transformation on the images as a method to measure interpretation easiness of seismology section. The goal of the study is to develop applications of image transformation tools to inhomogeneity detection of lithology-phacial structure of seam-like salt deposits.
