Well Integrity

It is important to ensure well integrity throughout the life-cycle of the well. At SINTEF, we are working with understanding and predicting failure of well barriers, as well as understanding how drilling operations and well design influence long-term well integrity during production and after abandonment.

Important areas are:

  • Integrity of annular sealants, such as cement and other sealant materials
  • Estimate of leakage rates and simulation of cement integrity
  • Influence of thermal cycling on well integrity
  • Cement-formation bonding
  • Well leakages and development of microannuli
  • Characterization of well barrier materials
  • Well abandonment
