A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings generated during the well drilling process. A generally cylindrical wire-wrapped screen having a bore therethrough rotates about its longitudinal axis. Suction pressure is applied through the inner bore of the cylindrical wire-wrapped screen. As fluid-laden drill cuttings are deposited on the outer surface of the cylindrical wire-wrapped screen, fluids are drawn off of the cuttings and evacuated from the inner bore of the cylindrical wire-wrapped screen. Solid components of the cuttings remain on the outer surface of the cylindrical wire-wrapped screen and eventually roll off the screen. A scraping member is provided to agitate cuttings deposited on the outer surface of the cylindrical wire-wrapped screen.

FIG. 1 is a schematic view of a mud system of drilling rig, including the present invention.
FIG. 2 is a perspective view of the apparatus of the present invention.
FIG. 3 is an exploded perspective view of the components of the present invention depicted in FIG. 2.
Referring to the drawings, FIG. 1 depicts a schematic overview representation of the mud system of a typical drilling rig. The flow of drilling mud within this mud system in FIG. 1 is in the direction of the arrows.
Still referring to FIG. 1, derrick 1 extends vertically over wellbore 2. Tubular work string 3 is inserted into wellbore 2, and extends from the earth's surface to a desired depth within said wellbore 2. Flow line 4a is connected to said tubular work string 3. Flow line 4b is connected to annular space 5 formed between the outer surface of tubular work string 3 and the inner surface of wellbore 2.
Still referring to FIG. 1, the bulk of the drilling mud for the depicted mud system is in mud pit 6. Mud from said mud pit 6 is circulated through the overall mud system depicted schematically in FIG. 1 via mud pump 7. The mud is pumped into tubular work string 3 through flow line 4a, circulated out the end 3a of tubing 3 up the annulus 5 of wellbore 2, and out of said wellbore annulus via flow line 4b.
