The effects of carboxymethylcellulose (CMC) polymer with some other additives on Class G
cement were investigated to design a slurry for a field in the south of Iran subject to
tectonically induced horizontal in-situ stress. For a number of alternative slurries,
characteristics such as compressive strength, permeability, free water, and fluid loss were
examined. Fundamental theoretical studies and laboratory experiments were conducted
using a system-based approach, endeavoring to minimize undesired properties …

Knowledge of uniaxial compressive strength (UCS) of carbonate rocks is essential in almost
every engineering project. Since appropriate core sampling is sometimes extremely difficult
(eg deep projects in petroleum industry), estimation of rock strength based on other rock
properties has always been a demanding alternative. In this research, it was clarified that
three parameters of Young's modulus (E), porosity (φ), and the Biot's coefficient (α) affect the
uniaxial compressive strength (UCS) of carbonate rocks. Since porosity in carbonates is …
