Piezoresistive cement nanocomposites

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 t...

Beschreibung
Zusammenfassung:	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.
