Title
(EN) FORMATION EVALUATION INSTRUMENT AND METHOD
(FR) INSTRUMENT ET PROCÉDÉ D’ÉVALUATION DE FORMATIONS
Abstract
(EN)
Subsurface formation evaluation comprising, for example, sealing a portion of a wall of a wellbore penetrating the formation, forming a hole through the sealed portion of the wellbore wall, injecting an injection fluid into the formation through the hole, and determining a saturation of the injection fluid in the formation by measuring a property of the formation proximate the hole while maintaining the sealed portion of the wellbore wall.
(FR)
L'invention concerne un procédé d’évaluation de formations souterraines comportant les étapes consistant, par exemple, à isoler une partie de la paroi d’un puits de forage pénétrant dans la formation, à pratiquer un trou à travers la partie isolée de la paroi du puits de forage, à injecter un fluide d’injection dans la formation à travers le trou et à déterminer une saturation du fluide d’injection dans la formation en mesurant une propriété de la formation à proximité du trou tout en maintenant isolée la partie considérée de la paroi du puits de forage.
