Extended Reach Drilling (DRI39)
Description
Extended Reach Drilling (ERD) presents unique engineering and operational challenges that require specialized planning and execution. This course delivers an advanced understanding of high angle well construction, hole cleaning, well monitoring, and directional drilling techniques, ensuring safe and efficient drilling of extended reach and complex wells.
This is an operationally focused course that goes beyond the basics of ERD well planning. Participants will gain a deep understanding of risk factors, operational hazards, and best practices to ensure successful well delivery while minimizing wellbore instability, nonproductive time (NPT), and well cost escalation.
The curriculum follows the latest research and addresses the highest risk areas associated with high angle and complex well drilling operations. The course also critically evaluates how proposed tools and techniques may impact project risk, ensuring informed decision making for complex wells.
Participants will gain practical knowledge that can be directly applied to ongoing drilling operations or future well planning. This training has been proven to deliver dramatic improvements in drilling performance, reduce costs, and increase operational efficiency.
All topics are placed in their operational context, ensuring that each subject is interrelated with the overall ERD drilling process.
