Horizontal Well Placement and Geosteering - HWP

Advances in technology have dramatically reduced the time needed to transmit down hole tool responses to those responsible for interpreting the data in the context of the geological play and the reservoir. It follows that geoscience would request course corrections, which would be relayed to the field, and over time take a more proactive role in ‘geosteering’ wells while drilling. However, advances in technology have also dramatically reduced the time needed to drill these wells, and proactively geosteering a well while drilling has come to require more than just an understanding of the geoscience. Geosteering personnel must now be able to gather and process incoming data and make targeting decisions with little time to spare. Down hole log responses must be understood within the context of the entire bottom hole assembly (BHA), including its limitations, and must incorporate trigonometry (for surveys and targeting) as well as the needs of the intended completion/production plan in order to modify targets for a well while drilling. Last but not least, there needs to be a clear process to communicate back to the field, so that the well site engineer and geologist are properly aligned. This 5-day course will introduce participants to the general concepts of Geosteering. The first 2 days of this course review BHA components, directional drilling, surveys and other necessary background knowledge at a level appropriate for the course. An example well and exercises introduce the skills needed to geosteer a well. Then the focus changes to interpretation, offering progressively more complex case study examples, and reinforcing log interpretation and early learnings as we review decision points on example wells. Along the way, pinch points are identified, and strategies to manage them are introduced, and for each example, completions intervals are identified.
