Title (EN) SYSTEM AND METHOD OF PERFORATING A WELL AND PREPARING A PERFORATING FLUID FOR THE SAME
(FR) SYSTÈME ET PROCÉDÉ DE PERFORATION D'UN PUITS ET PRÉPARATION D'UN FLUIDE DE PERFORATION POUR CEUX-CI
Abstract: front page image
(EN)A perforation fluid is prepared having a solid material suspended in a liquid. The solid material includes particles having particle sizes that correspond to the pore throat sizes of one or more geological formations through which a well to be perforated runs. The solid material is self-degrading. Perforation of a well-casing of the well in the perforation fluid causes the solid material to instantaneously (or substantially so) form a self-degrading filter cake that facilitates setting of the final completions of the well.
(FR)L'invention porte sur un fluide de perforation, lequel fluide a un matériau solide en suspension dans un liquide. Le matériau solide comprend des particules ayant des tailles de particules qui correspondent à des tailles de gorge de pore d'une ou plusieurs formations géologiques à travers lesquelles s'étend un puits devant être perforé. Le matériau solide est à auto-dégradation. La perforation d'un tubage de puits du puits dans le fluide de perforation provoque la formation instantanée (ou sensiblement instantanée) par le matériau solide d'un gâteau de filtre à auto-dégradation, qui facilite la réalisation des étapes d'achèvement finales du puits.
