Horizontal Well Re-fracturing
Feb 22, 2019 Houston
Instructor: Dr. Ali Daneshy
Horizontal well re-fracturing has become a popular method for boosting declining production in many existing horizontal wells. Successful re-fracturing needs to consider the existing large number of fractures, the type of completion and its integrity.
Who should attend. This course is designed for people who are, or planning to, re-fracture their horizontal wells. Some basic familiarity with hydraulic fracturing will be very helpful in maximizing course usefulness.
Contents. The presentation offers a systematic start-to-finish approach to successful re-fracturing.
Why, how, and where does re-fracturing work. Matching production objectives with re-fracturing system choices.
Influence of reservoir depletion, completion type (openhole or cemented liner) and its integrity
Re-frac Isolation systems; their strengths, weaknesses, and applications
CT deployed systems
Combination of chemical and mechanical diverters
Design of re-fractures
Practical considerations to enhance successful execution
