Corrosion is a major cost for the oil industry, and especially one form of corrosion is an expensive troublemaker in the production wells in the North Sea: The under-deposit corrosion. So far it has been impossible to predict and prevent. Two teams of researchers at DTU now collaborate with Maersk Oil on uncovering the mystery.

DHRTC's hypothesis

Any decrease in operational costs postpones the cut-off point when a field becomes uneconomic, and allows the field to be operated more optimally. The aim of this demo model is to find ways to reduce facility and well maintenance costs.

DHRTC’S HYPOTHESIS
  • Asset operating costs can be reduced by modularisation of maintenance activities
  • Well uptime can be increased through mitigation of corrosion and scaling
  • Well cost can be reduced through preventative activities based on probabilistic risk management
  • Well recovery can be enhanced through well conformance activities reducing water production
DHRTC RESEARCH
  • Cost reduction through novel modularized maintenance planning
  • Risk-based well intervention planning
  • Methods for prediction / inhibition / mitigation of scale deposition and corrosion in wells
  • Methods for mitigation of reservoir souring
  • Well conformance techniques to reduce water production
