Development of a structured workflow for enhanced well cement integrity: Lessons learned and the way ahead

With this in mind, a unique and systematic procedure is required to assess the array of dynamic factors which have proven to adversely affect the cement integrity of oil and gas wells. A data matrix consisting of a combination of cement, lithological, thermal, and hydraulic information must be employed to extensively evaluate cement integrity (Lavrov et al., 2014). From this input, a consequence analysis will be provided to assess the risks involved from disorganized and faulty cementing practices and techniques. This paper proposes an extensive literature review of currently published attempts to evaluate cementing integrity, and the necessity of a more expansive construct to evaluate long-term primary and secondary cementing environments.
