Title
(EN) DOWNHOLE SEGREGATION FOR WIRELINE FORMATION FLUID SAMPLING
(FR) ISOLEMENT DE FOND DE TROU POUR ÉCHANTILLONNAGE DE FLUIDE DE FORMATION PAR CÂBLE
Abstract
(EN)
The disclosure provides for a method for sampling fluid from a subterranean formation that is intersected by a wellbore. The method includes performing an initial draw-down at a target interval in the wellbore to pump fluid from the subterranean formation with a 3D radial probe. The method includes isolating the target interval of the wellbore with a packer and providing a residence time within a dead volume of the packer to allow fluid therein to separate into hydrocarbon and water phases. The method includes pumping a sample of the hydrocarbon into a sample chamber while pumping a remainder of the fluid into the wellbore, and testing the sample to determine a hydrocarbon content of the sample.

L'invention concerne un procédé d'échantillonnage de fluide dans une formation souterraine qui est coupée par un puits de forage. Le procédé comprend la réalisation d'un tirage initial à un intervalle cible dans le puits de forage pour pomper un fluide de la formation souterraine avec une sonde radiale 3D. Le procédé comprend l'isolation de l'intervalle cible du puits de forage avec un packer et la fourniture d'un temps de séjour à l'intérieur d'un volume mort du packer pour permettre à un fluide situé à l'intérieur de ce dernier de se séparer en phases d'hydrocarbure et d'eau. Le procédé comprend le pompage d'un échantillon de l'hydrocarbure dans une chambre d'échantillon tout en pompant un reste du fluide dans le puits de forage, et le test de l'échantillon pour déterminer une teneur en hydrocarbure de l'échantillon.
