Patent ID: 10704343

Abstract:
A system for launching or retrieving wireline electro acoustic technology (EAT) sensor assemblies in a downhole wellbore comprises an EAT launcher/retriever section and an EAT sensor assembly for placement in the EAT launcher/retriever section. The EAT launcher/retriever section comprises an external high pressure housing, attachment means at each end of the external high pressure housing, and a wedge shaped internal retractable launcher plate with an opening on one side to allow a fiber based wireline cable to pass through the EAT launcher section. The EAT sensor assembly comprises a center section comprising sensors and two end sections, each end section with a set of extendable grippers to grip a fiber based wireline cable, wherein the center section and both end sections comprise a V groove that allows the EAT sensor assembly to be centered on the fiber based wireline cable.
