A method of and product for use in cementing the annulus of a hydrocarbon well having a casing centered within a hole bored from a surface. The method comprises the steps of introducing an effective amount of colouring agent contained in a water-soluble bag into a portion of spacer or scavenging fluid, pumping the spacer or scavenger and a then cementing slurry down the casing to the bottom of the hole to displace drilling mud upwardly through the annulus to the surface, until the colouring agent becomes visible at the surface, displacing the casing volume and then stopping the pumping and allowing the pumped cement slurry to harden.
Procédé et produit à utiliser dans la cimentation de l'espace annulaire d'un puits d'hydrocarbures ayant un tubage centré dans un trou foré à partir d'une surface. Le procédé comprend les étapes consistant à introduire une quantité efficace d'agent colorant contenu dans un sac hydrosoluble dans une portion de fluide de séparation ou de récupération, pomper le séparateur ou le récupérateur, puis faire descendre une suspension épaisse de cimentation dans le tubage jusqu'au fond du trou pour déplacer la boue de forage vers le haut à travers l'espace annulaire vers la surface, jusqu'à ce que l'agent colorant devienne visible à la surface, déplacer le volume de tubage, puis arrêter le pompage et laisser la suspension épaisse de ciment pompée durcir.
