What is your challange?

• Corrosion 
  (of tubing and other wellbore assembly elements)
• Fishing
  (of dropped and accidentally lost downhole tools)
• Obstruction
  (of inflow into the well)
• Valve Failure
  (of safety and regulatory/gaslift valves in the nipples or tubing-pockets)
• Scale
  (barite and other chemical scaling in the borehole during oil production)
• Leakage
  (due to isolation and fitting problems, or faulty seals)
