In the complex field of carbonate reservoir evaluation, the intricate structural features present significant obstacles. This study tackles the essential task of structural delineation, with a particular focus on fractured reservoirs, and highlights the crucial influence of permeability on the performance of wells and reservoirs. The Oil Based Mud Micro-Imager - resistivity of invading zone (OBMI-Rxo) offers a high-resolution curve that is sensitive to fluid mobility near the borehole wall, although it is often underexploited by oil companies. Maintaining borehole stability after drilling is critical for ensuring the longevity of wells. This research introduces a holistic workflow that combines borehole imagery, petrophysical logs, the Modular Formation Dynamics Tester (MDT), Xpress Pressure Tool (XPT), and core samples for sophisticated formation evaluation in both carbonate fractured and clastic reservoirs. The study reveals new insights into reservoir structure, fracture detection, visualization of rock texture, and permeability distribution, thereby improving our understanding of well conditions in these challenging geological environments.
