IN SITU GENERATION OF NANO-CLAY DRILLING FLUID

A method includes adding a clay to water to form a suspension of clay in water, the clay including pieces of clay having an average diameter of at least 2 µm; adding a dispersant to the suspension of clay in water to form a drilling fluid; and injecting the drilling fluid into a well. In the drillin...

Zusammenfassung:	A method includes adding a clay to water to form a suspension of clay in water, the clay including pieces of clay having an average diameter of at least 2 µm; adding a dispersant to the suspension of clay in water to form a drilling fluid; and injecting the drilling fluid into a well. In the drilling fluid, the dispersant interacts with the clay to form nanoscale particles of clay having an average diameter of less than 500 nm. La présente invention concerne un procédé comprenant l'ajout d'une argile à de l'eau pour former une suspension d'argile dans l'eau, l'argile comprenant des morceaux d'argile ayant un diamètre moyen d'au moins 2 µm; l'ajout d'un dispersant à la suspension d'argile dans l'eau pour former un fluide de forage; et l'injection du fluide de forage dans un puits. Dans le fluide de forage, le dispersant interagit avec l'argile pour former des particules nanométriques d'argile ayant un diamètre moyen inférieur à 500 nm.
