Title
(EN) TIME-DOMAIN BROADBAND DIELECTRIC LOGGING
(FR) DIAGRAPHIE DIÉLECTRIQUE À LARGE BANDE DANS LE DOMAINE TEMPOREL
Abstract
(EN)
Described are tools, systems, and methods for dielectric logging using transient waveforms. In some embodiments, one or more microstrip antennas are employed for the measurements. In various embodiments, the waveforms are processed in the time-domain to determine the dielectric properties of a formation, from which geophysical formation properties can then be derived. Further embodiments are disclosed.

L'invention concerne des outils, des systèmes et des procédés de diagraphie diélectrique à l'aide de formes d'onde transitoires. Dans certains modes de réalisation, une ou plusieurs antennes microruban sont utilisées pour les mesures. Dans divers modes de réalisation, les formes d'onde sont traitées dans le domaine temporel pour déterminer les propriétés diélectriques d'une formation, à partir desquelles des propriétés de formations géophysiques peuvent alors être déduites. D'autres modes de réalisation sont décrits.
