Merlin can help you maintain your well integrity
Identification and mitigation of downhole leakage is critical for regulatory compliance and for maintaining licence to operate. Leaking fluids can pose a safety risk as well as an environmental hazard. Degradation of downhole barriers over time allows migration of fluids behind casing, or directly through corroded casing or tubing. This fluid can then migrate to surface and build pressure in well annuli or leak around well heads. Geochemical fingerprinting can help identify the source of those fluids which, in combination with subsurface evaluation prior to well workover, reduces uncertainties leading to safer and more efficient operations which in turn reduce costs.
What's involved?
- ANALYSE the leaking fluids to identify their geochemical character.
- IDENTIFY the most likely subsurface origin of the fluids by integrating geochemical analysis with existing subsurface data.
- DETECT the source of the leak by combining the subsurface data with well engineering and production history records.
- REPAIR the failed barrier and restore well integrity.
