Downhole Remediation for Mature Oil and Gas Wells is presented from a practical point of view. Discussions include decision processes for selection, design, and application of methods that are supported by field experiences and research results. Principal focus is production-related near wellbore damage and remedial water control practices.

How To:
  • Diagnose and develop removal and prevention techniques for wellbore damage due to scale, paraffin, asphaltenes, corrosion, and erosion
  • Understand sources, causes, and effects of water production
  • Design remediation applications (both mechanical and chemical) for reducing excess water production
  • Design sand control applications and understand how to fix damaged screens and gravel packs
  • Understand how and when to apply remedial cementing practices and what tools and job considerations are critical
  • Apply these techniques to a specific well problem that you bring into the classroom from your current field assignment
