Abstract
A system of translatable electro acoustic technology (EAT) modules for deployment along an oil or gas wellbore casing includes: a wireline/slickline optical distributed acoustic sensing (DAS) cable deployed from the surface into the casing and connected to a surface interrogator; a tractor attached to the downhole end of the wireline/slickline optical distributed acoustic sensing (DAS) cable; and one or more EAT sensing modules that can be coupled to or decoupled from the wireline/slickline optical distributed acoustic sensing (DAS) cable at pre-selected locations and can either be coupled to or decoupled from the casing of the wellbore or be allowed to reposition along the wellborn casing, wherein the one or more EAT sensing modules can conduct multiple measurements and communicate the results via the wireline/slickline optical distributed acoustic sensing (DAS) cable to the surface interrogator.
