Title
(EN) TERAHERTZ ANALYSIS OF A FLUID FROM AN EARTH FORMATION USING A DOWNHOLE TOOL
(FR) ANALYSE TÉRAHERTZ D'UN FLUIDE D'UNE FORMATION TERRESTRE À L'AIDE D'UN OUTIL DE FOND
Abstract
(EN)
Method and apparatus of analyzing a fluid from an earth formation using a downhole tool. In the method, the downhole tool is conveyed down a borehole in the earth formation, and a fluid drawn into a measurement portion of the downhole tool, where a spectroscopic measurement of the fluid is made in a terahertz radiation domain. The method may be part of a method of producing a mineral hydrocarbon material from an earth formation.
(FR)
Procédé et appareil d'analyse d'un fluide d'une formation terrestre à l'aide d'un outil de fond. Dans le procédé, l'outil de fond est dirigé le long d'un trou de forage dans la formation terrestre et un fluide est tiré dans une partie de mesure de l'outil de fond, où une mesure spectroscopique du fluide est réalisée dans un domaine de rayonnement térahertz. Le procédé peut faire partie d'un procédé de production d'un matériau d'hydrocarbure minéral d'une formation terrestre.
