SYSTEM AND METHOD FOR DE-WATERING WASTE DRILLING FLUIDS

摘要

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.
