Simplifying Geosteering Interpretation and Decision Making in Complex Environments Using Deep Resistivity Images

Directional drilling, particularly in conjunction with reservoir navigation (i.e., geosteering), is used to land wells at<br>preplanned points in a reservoir and to optimize the wellbore placement of production sections with respect to<br>reservoir boundaries and fluid contacts, by adjustment of well trajectories in real-time. Geosteering is<br>accomplished and facilitated by the recognition of approaching conductivity contrast boundaries not yet<br>penetrated by the wellbore by the use of deep reading tools and geologic models used to predict the boundaries<br>approach.
