Geosteering has moved well past picking tops on an LWD log. In today's operations, the teams that consistently land wells in the best rock are the ones combining real-time geological data with live drilling parameters — and acting on both together, in the same interpretation.


This one-hour session is a practical, step-by-step walkthrough of geosteering a complex horizontal well using this integrated approach. Rómulo Cuevas will demonstrate how to build a strong pre-drill framework from offset wells, correlate live LWD logs in True Vertical Thickness (TVT) space, overlay real-time drilling mechanics on the geological interpretation, and update the target line on the fly — communicating changes to the rig without breaking the workflow.


If your subsurface and drilling teams still work in parallel rather than together, this session will show what a fully integrated geosteering workflow looks like in practice — and how it changes decision quality on the well.

Webinar Objectives

By the end of this webinar, participants will be able to:


Build a robust pre-drill structural grid and cross-section from offset well data


Correlate live LWD logs with an offset database in True Vertical Thickness (TVT) space


Calculate structural dips with confidence during real-time operations


Overlay real-time drilling mechanics on the geological interpretation to separate formation changes from drilling issues


Distinguish between lithological changes and drilling hazards while the bit is turning


Execute target line updates and communicate revised well paths to the rig team without delay


Bridge the workflow gap between subsurface interpretation and drilling execution


Questions We’ll Explore Together


How can you distinguish between lithological changes and drilling hazards in real time?


What are the most reliable indicators for identifying formation boundaries while drilling?


How can integrating drilling mechanics improve your geological interpretation?


What workflows enable faster, more effective collaboration between subsurface and drilling teams?


How can real-time updates to the well path improve overall drilling performance and outcomes?
