Real-time monitoring of cement sheath integrity under high-angle HPHT wellbore conditions.
The lengthy time span over which the cemented well needs to retain its integrity is a massive challenge today. The cement plugs in abandoned wells, in conjunction with the annular cement sheath, need to prevent leakages well beyond the life of the wellbore. The results of a recent engineering study …

Characterizing the Behavior of Smart Oil Well Cement for Enhancing the Monitoring of Cement Sheath Integrity
Oil well cementing is one of the most important and yet complex steps of a drilling project. One of the challenges in maintaining the well integrity is in monitoring the performance of oil well cement (OWC) used in the construction of the well. Recent oil well failures have clearly identified the …

Emergence of Delamination Fractures around Casing and Its Stability
The cement sheath failures and nearby wellbore failures may lead to upward flow of drilling fluid or formation fluid, which may have significantly adverse consequences like loss of reserve and environmental hazards. In order to maintain wellbore integrity in the long term, it is expedient to …
