Geosteering Using Software

This comprehensive Geosteering course combines a well-structured theoretical foundation — concise, essential, and easy to grasp — with practical training using the cutting-edge StarSteer software by ROGII.

The training begins with fundamental theory, followed by the step-by-step creation of a geosteering model.

Key workflows are then introduced, including model-based and stratigraphic methods, borehole image interpretation, and bed boundary inversion — powerful StarSteer features for advanced geosteering tasks.

Finally, we reinforce these skills through practice with three dedicated geosteering simulators.

By the end of the course, participants will be capable of interpreting geological data, optimizing well placement in real time, adjusting drilling trajectories, and making confident, data-driven decisions using industry-standard geosteering technology.

Description

Geosteering is a crucial technique in modern drilling operations, enabling engineers and geoscientists to optimize well placement while drilling. This course provides hands-on training in geosteering software, covering fundamental concepts, real-time data interpretation, and advanced decision-making techniques. Participants will gain practical experience in adjusting well trajectories based on formation evaluation, increasing hydrocarbon recovery, and minimizing drilling risks.
