Downhole video is a diagnostic tool used to provide visual diagnosis of complex wellbore problems and for viewing fluid entries of oil, water, and gas to empower operators with the confidence they need to take remedial action on their well. With proper diagnosis, the best solution can be employed to return problem wells back on production. Video dramatically reduces time and expense with trial and error approaches diagnosing well problems. Applications for downhole video are numerous though most would fall into one of the following three categories:

• Size
  
• Orientation
  
• Location
  
• Go / No-Go
• Decision

• Restriction
• Obstruction
• Damage
• Perforation:
  • size
  • location

• Tubulars
• Scale Buildup
• Corrossion
• Whipstocks
• Window
• Plug orientation
• Laterals
• Fractures
  • size
