Drilling Engineering Design (Software)

DESCRIPTION

This course will address the basic steps required by the well construction team (drillers, engineers, geoscientists) to develop a robust well plan from basic data available from seismic and offset wells. This course is focused on the fundamentals issues that must be addressed in the drilling plan and during well execution to insure safety and optimum performance. The course will deliver unmatched attention to early diagnostic trends of well problems and provide proactive preventive measures, a fundamental milestone to drilling optimization. The participants will walk away from this course carrying a solid understanding of drilling planning, optimum execution strategies, and well informed on safety issues throughout the well construction process. In addition, the participant will appreciate the importance of team building and communication in the overall success of the drilling project. The course will include a healthy mix of fundamentals and contemporary state of the art drilling topics.
