Title (EN) FORMATION TESTING
(FR) ESSAI DES COUCHES
Abstract: front page image
(EN)Formation testing which may involve circulating mud in a pipe string from a mud pit through a port in the pipe string to a downhole diverter sub, wherein the pipe string is suspended in a wellbore extending into a subterranean formation, operating a downhole pump to pump formation fluid from the formation, wherein the formation fluid comprises gas, and mixing the pumped formation fluid with circulated mud such that a proportion of the pumped formation gas in the circulated mud is maintained below a threshold value.
(FR)L'invention concerne l'essai des couches qui consiste à faire circuler la boue dans un train de tiges, depuis un bassin à boue par un orifice du train de tiges jusqu'à une réduction de déflecteur de fond de trou, le train de tiges étant suspendu dans un puits de forage s'étendant dans une formation souterraine, activer une pompe de fond de trou afin de pomper le fluide de la formation, le fluide de la formation comprenant du gaz, et mélanger le fluide de la formation pompé avec la boue en circulation de façon à maintenir dans la boue en circulation un volume de gaz pompé au-dessous d'une valeur seuil.
