Mitigating Frac-Driven Damage to Horizontal Wells & Their Production: Causes, Types, Effects & Methods
Instructor: Dr. Ali Daneshy
Date: TBA, Houston
Using actual field data, this course offers a comprehensive coverage of the hottest fracturing subject of the day; wellbore and production damage caused by Frac-Driven Interactions (FDI)s in horizontal wells and methods of mitigating their costly negative effects.
Interactions between fractured horizontal wells have become a common occurrence. If not addressed properly, the negative effects in the offset wells are known to include production loss, liner damage and rupture, frac fluid and even proppant invasion damaging the production lifting equipment, and more. At a minimum, these events have necessitated very expensive and time-consuming wellbore clean-up operations and missed production days. Sometimes they have caused loss of production in both the new and offset wells, and even complete loss of a producing well.
Course contents, supported by actual field data, include:
- Types of FDI and their causes
- Multiple simple and cost-effective detection methods
- Identification and classification of the different types of interactions and their potential effects
- Current mitigation techniques and their effectiveness
Analysis of FDIs is also a very effective technique for determination of critical fracturing parameters, including:
- Estimates of fracture length and height
- Fracture orientation
- Fracture growth pattern
