PetroTeach offers a four-day course in Drillstring Design. The course is designed to provide drilling and well engineers with the competency required to design a drillstring for various well types. Using both vertical and directional well profiles, participants are guided through the drillstring design process for different scenarios in accordance with current industry standards. The drillstring design is performed from first principles and supported by spreadsheet-based calculations, ensuring that participants develop a solid understanding of the underlying design concepts. The course begins with tubular properties and progressively covers the various drillstring components, enabling participants to complete a full drillstring design. Key mechanical aspects of drillstring performance—such as vibration, torque and drag, and wear—are thoroughly addressed to ensure these factors are properly considered in the design process. The final day of the course focuses on drillstring inspection and integrity management.

Steve Nas holds master degree in drilling engineering from the Robert Gordon University in Aberdeen and has accumulated over 40 years of drilling engineering experience. Steve started in 1977 as a mud logger with Geoservices before becoming a wellsite drilling engineer in 1980. Initially working rigs as a wellsite drilling engineer around the Middle East and throughout Africa before working for Shell in the UK North Sea. In the mid 1990’s became heavily involved in coiled tubing and underbalanced drilling and later into managed pressure drilling. He has been teaching well engineering since obtaining his master’s degree in the late 1990’s and has taught numerous courses at all levels including MSc students and developed a large number of training courses. Now working as an independent consultant he provides a number of well engineering related courses and offshore coaching on challenging wells.
The participants should have a solid understanding of conventional drilling operations and at least 3 to 5 years of experience in drilling and rig operations. General understanding and knowledge of hydrostatic pressures and the associated calculation methods is an advantage. The course is intended for the disciplines listed below, as well as anyone with a specific interest in the topic:
• Drilling and Completion Engineers
• Drilling Contractor supervisory personnel
• Service Providers for Deepwater Wells
• Other relevant technical and operational staff
Intermediate
The participants will learn:
• Understanding of tubular properties.
• Know the classification of the major drillstring components.
• Know the process and design factors for a drillstring.
• Understand the components and their placement.
• Understanding of torque and Drag, and Hydraulics.
• Understand buckling, fatigue, drillstring dynamics and failures.
• Understand the requirements and processes for drillstring inspections.
