Title
(EN) SYSTEM AND METHOD FOR DE-WATERING WASTE DRILLING FLUIDS
(FR) SYSTÈME ET PROCÉDÉ DE DÉSHYDRATATION DE FLUIDES RÉSIDUAIRES DE FORAGE
Abstract
(EN) Systems and methods for de-watering waste drilling fluid. In some embodiments, the de-watering system includes a drilling fluid reclamation system receiving the waste drilling fluid from a wellbore and removing at least some solids from the waste drilling fluid, a manifold combining the waste drilling fluid from the drilling fluid reclamation system and organic polymers, whereby an aggregated mixture of solids in the waste drilling fluid and water are formed, and a centrifuge receiving the aggregated mixture and separating the solids from the water in the aggregated mixture, whereby solid drilling fluid waste and substantially colloidal-free water are formed.
(FR) L'invention concerne un système et un procédé de déshydratation de fluide résiduaire de forage. Dans certains modes de réalisation, le système de déshydratation comprend un système de récupération de fluide de forage qui reçoit le fluide résiduaire de forage provenant d'un puits de forage et élimine au moins une partie des solides du fluide résiduaire de forage, un collecteur qui combine le fluide résiduaire de forage provenant du système de récupération de fluide de forage à des polymères organiques, formant ainsi un mélange agrégé de solides dans le fluide résiduaire de forage et d'eau, et une centrifugeuse qui reçoit le mélange agrégé et sépare les solides de l'eau dans le mélange agrégé, donnant ainsi des déchets solides de fluide de forage et une eau sensiblement exempte de substances colloïdales.
