Abstract
Systems and methods for separating sand and other solids from oil and other fluids produced from a well. The present systems and methods introduce the fluids at relatively high speed into a generally cylindrical separation chamber. The fluids flow in a generally circular path within the chamber, causing the solids and higher density fluid/media to be urged outward from the axis of the chamber as the fluids flow from the upper portion of the chamber. Because the solids become concentrated at the outer wall of the chamber, the fluid in a central portion of the chamber is substantially free of the solids, and can be removed from the chamber via a fluid outlet. The solids concentrated at the outer wall of the chamber continue to move downward into an accumulation chamber in which the fluid speed is reduced, allowing the solids to settle out of the fluid.
