Introduction to Remedial Cementation

The main reasons for using remedial cementation procedures are to:

  • abandon specific reservoirs in a multiple reservoir completed well
  • seal off all perforations when abandoning a well to make sure crossflow between reservoirs is impossible
  • repair defective casing or liner cement jobs
  • repair casing leaks
  • isolate specific zones within reservoirs (to achieve lower gas / oil ratios, water / oil ratios, etc)
  • casing patch
  • tie back
  • Temporary abandon.
