| Geological studies are basic formof operations for the exploration and development of oil and gas fields.Preparation of topographical and geological maps and drawingcross section from thesemaps formspart of these operations. Existing lineaments in the study area are important, and should be considered in drawing the geological sections. The evaluation of wells stability is one of the important issues in engineering geology, because the instability of walls means the acceptance of unknown risks. The existing lineaments in the area can have an important role in the stability or instability of the walls of wells. The purpose of this study is to investigate surface lineaments arrangements. To achieve this goal, Landsat satellite images were used. Images were processed using different techniques and lineaments map was provided. In the next stage, artificial lineaments were removed from lineaments map and remaining lineaments largely reflected existing fractures in the region. In order to study more precise lineaments, field studies were conducted at 3 stations and dip and strike of fractures were measured at each station and rosette plot, contour plot, scatter plot and pole plot were plotted for each station. The results of this study show that the density of lineaments in different parts of the field is not the same, but in the northwestern part of the field, lineaments density is higher than the other parts. Lineaments extend in different directions, but the extension of lineaments in NE-SW direction is dominant. | ||
