In one of the biggest discoveries during last 10 years in South East Asia, two recent highly deviated wells with length of over 3000 m were drilled in order to enhance the understanding of the reservoirs properties and characterization (Figure 1). Logging while drilling (LWD) images were acquired, processed and interpreted. This was performed subsequent to the very first successful and largest multiwell geological reservoir characterization performed for this operator in South East Asia. After doing the conventional borehole dip and structural analysis for both wells, a unique integration approach has been implemented for both wells using some recent advanced interpretation platform in order to create 3D near well structural model. This model has been updated with formation tops. Several steps and workflow has been implemented and finally local update of static model has been performed. The resulted structure axis has been calibrated later with seismic based map showing a structural axis direction towards NE-SW which is matched with the seismic derived structure map.
