Prediction of Fractures and Cracks to Improve the Drilling Operations

Abstract

The term fracture is defined in different ways in geology; some definitions have a defining aspect, while other definitions have dealt with this issue in more detail. There may be differences in appearance and strength that distinguish them from each other, generally in the drawings of an illustrator diagram. According to electrical logs such as formation micro-imager (FMI), fractures are seen in three vertical fractures, polygonal fractures and mechanical fractures. In this paper, different types and methods of diagnosis of each fracture were evaluated. Moreover, by showing examples of these fractures, especially mechanical fractures in the FMI tool’s images, we become practically acquainted with these construction features. According to the findings of this study, large open cracks cause considerable variations in dense, shear, and columnar values, and large vertical cracks are due to significant differences in shear tension.
