Learning Objectives
Attendees will be able to implement the following skills:
gain knowledge of the fundamentals of telemetry, measurements and logging while drilling and directional drilling technologies,
become aware of the criteria for selecting the minimum required logging data set before a geo-steering job, and get acquainted with errors and uncertainties in the drilling of horizontal wells, related both to geol-ogy and to the limitations of telemetry and logging tools, and the methods of calculating the well trajectory,
master the modern geosteering methods and become familiar with the basics of interpreting azimuthal logs.
Ways & Means
Geosteering requires practice, and this is inevitably associated with making mistakes and wrong decisions. The price of making a wrong decision on a real well can vary from a few hours of non-productive time to a million-dollar sidetrack or a million barrels of oil that can never be extracted. These factors make learning on a real horizontal well an extremely expensive training ground.
Participants will master the necessary knowledge to build a preliminary simulation and develop a strategy for drilling a horizontal well.
Using a unique interactive simulator, participants will independently follow the drilling of at least three horizontal wells, while learning how to independently make timely and technically correct trajectory corrections.
Learning assessment
Practice on geosteering simulator, debriefing, evaluating of effective length of the well after geosteering.
