Well Completion and Intervention (PET690)

The well completion part deals with lower and upper completion systems. The starting point is inflow performance and thorough treatment of skin factor is given.  Openhole and perforated lower completions are discussed in detail.  Extra attention is given to sand control.  Gas-lift and electrical submersible pumps are discussed with brief comparison to other artificial lift methods.  The last segment explains completion equipment and installing the completion.  Calculations include skin factor, gravel-packing and other completions scenarios.  The well intervention part starts off with well mechanics including the use of effective force and Lubinski yield circle.  There is theoretical emphasis on buckling of the well intervention pipe.  Well intervention methods such as pumping, wireline, coiled tubing and snubbing are covered in great detail.  Mechanical well failures, well productivity issues, well intervention equipment, barriers, standards and regulations, different types of operations, choice of intervention technology and various relevant calculations are discussed.  Both platform and subsea well intervention methods are included.

After completing this course the student should have knowledge about:

• Work duties and work structures for a well engineer
• Well programs and operational procedures
• Standards and regulations for well equipment, completion and intervention
• Well completion solutions with emphasis on design, equipment and barriers
• Inflow performance, skin factors
• Stand-alone screens, openhole gravel-packing, cased and perforated lower completion
• Life of well operations
• Gas-lifted wells, electrical submersible pumps, other artificial lift methods
• Completion equipment, installing the completion
• Well repair and maintenance using pumping, wireline, coiled tubing and snubbing
• Platform operations, subsea operations
• Well completion failure detection, well intervention application areas
• Proposed well intervention solutions for different types of well problems
