This course is designed for all consumers of geosteering data and for authors of geosteering models. It will introduce basic principles, types and limitations of data, tools to discern high and low confidence models, and best practices for live operations and retroactive (post-drilling) studies. Participants will learn from real-life examples of structural features, stratigraphic variation, and tool failures. The course will address how to scrutinize and manage geosteering models produced by a third party. It will also consider the value of ‘batch’ geosteering, in which geosteering models of nearby wells are tied/compared to each other for an enhanced view of the subsurface. Geosteering is a high-resolution tool that can play a major role in the successful execution of a drilling program. Adept geosteering practitioners will save their companies time and money, enhance economic returns, and provide valuable insight to improve understanding of the reservoir. Participants in this course will gain a solid foundation in both the creation and contextual application of high confidence geosteering models.
