Oceanit’s Scanite delivers the future of digital well integrity monitoring. Scanite provides valuable, real-time well integrity information that is not currently available.
In the energy sector, cement provides the seal, protection, and support for casing pipe to maintain the strong barriers of a safe, isolated oil or gas well. The smart, acoustically-responsive Scanite technology is a game-changer for the digital monitoring of well integrity.
Oceanit’s Scanite technology adds remarkable risk-reduction value; allowing for accurate monitoring and detecting of cement stresses, formation issues, and enhanced well integrity.
Cementing is a crucial part of well construction. Cement is used to fill the area around a well casing in order to isolate and provide three essential functions:
- Mechanical support of the casing
- Prevent fluid from leaking to the surface
- Physically isolate different zones of the well
Wells can experience integrity failure when these cemented regions begin to deteriorate or become highly stressed for a variety of reasons, including subsidence and compaction caused by reservoir depletion over the lifetime of the well.
To measure well integrity, acoustic tools are used to log the quality and condition of the cement and its bond. However, current acoustic logs do not measure cement quality directly. Rather, well integrity is inferred from the degree of acoustic coupling of the cement to the casing formation.
When properly run and analyzed, cement-bond logs can provide rough estimates of well integrity and zone isolation. However, they are often open to interpretation based upon the cement-casing bond and do not provide a complete picture of cement quality and environmental conditions.
Information from a Scanite-enabled well can be easily read using existing acoustic logging tools, but provides far more insight to operators.
Scanite data is analyzed to directly determine the integrity of the cement, contamination, and most importantly the mechanical loading on the cement. This allows for the improved determination of cement placement, discrimination between fluids and lightweight cement, monitoring of formation depletion and reservoir compaction, and increased knowledge of wellbore mechanical stress states in the oil field.
This vital data is not currently available to well operators today. Scanite can be used to harness the potential of the unified digital oil field by increasing productivity and consistency.
- Directly allows operators to determine the integrity of cement and formation issues (depletion and reservoir compaction)
- Gives accurate monitoring and detecting of cement stresses
- Functions with existing acoustic logging tools, but provides far more insight
- Allows determination of cement placement, discrimination between fluids/lightweight cement, etc.
