    摘要： An inert (non-radioactive) tagging material can be added to cement in a wellbore. The non-radioactive tagging material can emit radiation at a specific energy level when irradiated with radiation. A logging tool containing a radiation source can be introduced into a wellbore and activated to emit radiation. The logging tool can detect the radiation emitted from the non-radioactive tags within the wellbore. Accordingly, integrity of cement, particularly low density cements that have a density close to that of fluid provided to or contained within a hydrocarbon-bearing formation, can be determined from the detected radiation.

    摘要： Design optimization methods can be used to design concrete mixtures having optimized properties, including desired strength and slump at minimal cost. The design optimization methods use a computer-implemented process that is able to design and virtually “test” millions of hypothetical concrete compositions using mathematical algorithms that interrelate a number of variables that affect strength, slump, cost and other desired features. The design optimization procedure utilizes a constant K (or K factor) within Feret's strength equation that varies (e.g., logarithmically) with concrete strength for any given set of raw material inputs and processing equipment. That means that the binding efficiency or effectiveness of hydraulic cement increases with increasing concentration so long as the concrete remains optimized. The knowledge of how the K factor varies with binding efficiency and strength is a powerful tool that can be applied in multiple circumstances. A concrete manufacturing process may include accurately measuring the raw materials to minimize variation between predicted and actual strength, as well as carefully controlling water content throughout the manufacturing and delivery process.
