Title
(EN) REAL-TIME MONITOR AND CONTROL OF ACTIVE CLAY IN WATER-BASED DRILLING FLUIDS
(FR) SURVEILLANCE ET RÉGULATION EN TEMPS RÉEL D'ARGILE ACTIVE DANS DES FLUIDES DE FORAGE À BASE D'EAU
Abstract
(EN)
Systems and methods for this disclosure describe systems and methods that are directed to monitoring active clay in water-based drilling fluid may be provided. A method for monitoring active clay concentration while drilling may be provided. The method may include providing a sample of water-based drilling fluid. The method may further include adding methylene blue to the sample in a methylene blue titration. The method may further include performing an impedance measurement on the sample during the methylene blue titration. The method may further include determining an endpoint of the methylene blue titration using a phase angle measurement from the impedance measurement. The method may further include correlating the endpoint to the active clay concentration of the sample. The method may further include determining a treatment for the water-based drilling fluid based on the active clay concentration.

La présente invention concerne des systèmes et des procédés qui sont conçus pour surveiller une argile active dans un fluide de forage à base d'eau. L'invention concerne également un procédé de surveillance de la concentration en argile active pendant le forage. Le procédé peut comprendre la fourniture d'un échantillon de fluide de forage à base d'eau. Le procédé peut en outre comprendre l'ajout de bleu de méthylène à l'échantillon dans un essai au bleu de méthylène. Le procédé peut en outre comprendre la réalisation d'une mesure d'impédance sur l'échantillon pendant l'essai au bleu de méthylène. Le procédé peut en outre comprendre la détermination d'un point d'extrémité de l'essai au bleu de méthylène à l'aide d'une mesure d'angle de phase à partir de la mesure d'impédance. Le procédé peut en outre comprendre la corrélation du point d'extrémité avec la concentration en argile active de l'échantillon. Le procédé peut en outre comprendre la détermination d'un traitement pour le fluide de forage à base d'eau sur la base de la concentration en argile active.
