An Integrated Approach to Study Cement-to-Formation Bonding

It is crucial to assess the bond strength of cement–formation interface while developing novel cements for efficient zonal isolation. An integrated method presented investigate failure mechanism in cement and formation rock under downhole reservoir temperature pressure conditions using a triaxial experimental setup. The acoustic emission count, strain, velocity data aid inferring fracture process that led specimen. Although most specimens investigated exhibit three dominant events compaction, multi-cracking, sliding, there are variations basic structure each Furthermore, insight obtained about internal specimen points its damage tolerance, both which vital requirements bonding. This can distinguish between standard modified very effectively help pairing appropriate formulation rock.
