A comprehensive analysis of class H cement Unconfined Compressive Strength using cubical and cylindrical samples

Drilling operations in recent years have gone into much deeper depths to meet the global demands. Therefore, it becomes important that the well integrity is maintained throughout its life and in that respect, well cement plays an important role. For the proper application of the cement in the well, it is important to have a better understanding of its mechanical properties. The study will focus on the techniques to perform Unconfined Compressive Strength (UCS) tests according to API Standard (cubes) and cylinders having a length to diameter ratio of 2. Moreover, a review of ASTM and British standards for the UCS is given.
