Abstract

Summary

Azimuthal resistivity tools and extra-deep azimuthal resistivity, coupled with multicomponent inversion modelling of the resistivity profile, allow detecting multiple target boundaries away from the wellbore. The ability of resistivity tools to trace far boundaries, coupled with the results of resistivity inversion modelling, can also significantly enhance the understanding of the structural trends with high accuracy and resolution.

However, despite the ability of resistivity tools of mapping one or more formation boundaries along the wellbore, this detailed structural information is commonly neglected when reservoir navigation data are imported in the pre-well 3D structural models, which are based on seismic and well correlation data.

The case history presented shows how the structural trends, mapped by means of extra-deep azimuthal resistivity during the drilling of a horizontal well within a thick sand reservoir, can be integrated into the 3D geological model, increasing its resolution and providing an enhanced view of the structural trends.
