    Abstract: Methods may include pumping a cement composition containing one or more conductive fillers into an annular region of a wellbore created between a casing and a surface of the wellbore, allowing the cement composition to cure, emplacing a tool for measuring at least one electromagnetic property into the wellbore, and measuring at least one of the cemented casing and the formation. In another aspect, methods may include preparing a cement composition containing one or more conductive fillers, allowing the cement composition to set, and measuring at least one electromagnetic property of the set cement. In yet another aspect, cement compositions may contain a cement, one or more conductive fillers, and a surfactant, wherein the resistivity of the cement composition is less than 10 Ω*m.

    Abstract translation: 方法可以包括将含有一种或多种导电填料的水泥组合物泵入在井筒和壳体的表面之间产生的井筒的环形区域中,从而允许水泥组合物固化,将用于测量至少一种电磁特性的工具放置在 井筒,并测量胶结套管和地层中的至少一个。 在另一方面,方法可以包括制备含有一种或多种导电填料的水泥组合物,允许水泥组合物凝固,并测量凝固水泥的至少一种电磁特性。 在另一方面,水泥组合物可以含有水泥,一种或多种导电填料和表面活性剂,其中水泥组合物的电阻率小于10Ωm。
