2-12/4T4 Mud Cleaner


The M-I SWACO 2-12/4T4™ MUD CLEANER is comprised of one 1,000-gpm (3,785-Lpm) 2-12 D-SANDER™, one 900-gpm (3,407-Lpm) 6T4 D-SILTER® and one 2-12/4T4 ADJUSTABLE LINEAR Shaker. The D-SANDER and D-SILTER hydroclones are mounted over the screening surface of the 2-12/4T4 Shaker to create a high volume 2-12/4T4 MUD CLEANER.

The 2-12 D-SANDER includes two 12" (305-mm) diameter polyurethane hydroclones slant mounted over the shaker. Each D-SANDER clone includes four replaceable wear resistant polyurethane sections that are joined together with quick release stainless steel clamps. The D-SANDER is furnished with an 8" (203-mm) diameter feed manifold and a 10" (254-mm) diameter discharge manifold and a 0-60 psi (4.1-bar) pressure gauge. The D-SANDER also includes a solids discharge trough to distribute the hydroclone underflow evenly onto the screening surface.

The 4T4 D-SILTER includes eight 4" (102-mm) polyurethane hydroclones mounted over the 2-12/4T4 Shaker. The D-SILTER is furnished complete with twin-cone replaceable polyurethane feed and apex sections. The D- SILTER also includes a 6" (152-mm) diameter feed manifold, an 8" (203-mm) diameter discharge manifold, a 0-60 psi (4.1-bar) pressure gauge and a discharge trough to distribute the hydroclone underflow evenly onto the screening surface.

The 2-12/4T4 Shaker is a single deck full view shaker design with two 4' x 4' (1,219-mm x 1,219-mm) screen panels to provide 32 square feet (2.97 square meters) of screening area. Screen tensioning is provided by quick release tensioning on each side. The deck angle is adjustable from +3 degrees to -3 degrees with a positive jacking device. The vibrating assembly consists of two explosion-proof, eccentric motors and starters. The vibration angle is adjustable from 25 degrees to 65 degrees in 10-degree increments to change amplitude and set the "g" force to a maximum of 6.25 "g's". The 2-12/4T4 Shaker is provided with adjustable diverter vanes with a louvered flow weir/dam to control the distribution of drilling fluid onto the screening surface. The fluid collection tank (possum belly) includes a 10" (254-mm) diameter pipe for connection to the fluid feed line (flow line).

Features & Benefits

  • Environmentally Efficient – The 2-12/4T4 MUD CLEANER provides efficient removal of sand and silt particles larger than 20 microns, and some as small as 15 microns. Removing and drying drilled solids helps meet environmental regulations by minimizing waste generated and reducing disposal cost.
  • High Performance – Processing capacity of 1,000 gpm with the 2-12 D-SANDER and 900 gpm with the 4T4 D-SILTER concentrates solids onto a classification shaker.
  • Versatile – The 2-12/4T4 MUD CLEANER can be operated with the 2-12 D-SANDER, 4T4 D-SILTER or both to process weighted or unweighted fluid systems.
  • Extends Equipment Life – The 2-12/4T4 MUD CLEANER helps minimize maintenance, repair and replacement of downstream equipment.
  • Reduces Operating Cost – The 2-12/4T4 MUD CLEANER reduces sand and silt-size particles and saves liquid, thus reducing mud cost, chances of stuck pipe and lost circulation and improving rate of penetration.
  • Reduces Disposal Cost – The 2-12/4T4 MUD CLEANER minimizes waste generated thus reducing disposal cost.
