Patent ID: 7377336

Claim:
An apparatus for controlling operating pressure in and managing waste from a subterranean borehole, said apparatus comprising: a pressure control section in fluid communication with the borehole and controlling an operating pressure of a fluid in the borehole, wherein the fluid also includes solids and entrained gas; a gas separator in fluid communication with the pressure control section, wherein the gas separator removes entrained gas from the fluid; a vibratory separator in fluid communication with the gas separator, wherein the vibratory separator removes solids having a size greater than a predetermined size from the fluid; a collection tank having a plurality of pits therein, wherein a first pit receives the separated fluid from the vibratory separator; wherein the separated fluid is returned to the borehole from the collection tank; a trough receiving the separated solids; an auger within the trough for conveying the separated solids through and from the trough; a pair of solids collection containers positioned to receive the separated solids discharged from the trough; and wherein the auger is reversible to selectively convey the separated solids to either the first solids collection container or the second solids collection container.
