For some project of oil, workover drilling and geothermal drilling, which needs the drilling mud overflow to the shale shaker buffer box directly, sometimes the well head height is not so high, GN provide low-profile shale shaker to meet the special requirement. The minimum weir height of GNZS703 shale shaker can reach 500mm, with 6.5 ~7.0 G, screen area 28sq.ft.We already shipped a complete mud system to New Zealand with such low-profile shale shaker.

Solids Control is one of the most important process of drilling. The reason for using mechanical solids control equipment is to remove detrimental drilled solids from the mud system. Effectively removing unwanted solids from the drilling fluid on the first pass through the solids control equipment is an important factor in maintaining drilling fluid properties and reducing drilling fluid cost. 

Mechanical solids control equipment including: shale shaker(separated by wire mesh), mud cleaner, desander, desilter( by accelerated G-force) and decanter centrifuge.

GN produced decanter centrifuge for drilling fluids, bowl assy is the main body of the decanter centrifuge. Bowl assy including collection box, bowl, inner tube, screw propeller, gear box, hydraulic coupler, pulleys, bearings, etc.

Bowl is the most important component, in includes taper piece and straight piece, previous production procedure is to make them separately and connected by bolts, GN produced centrifuge bowl is one piece bowl, the connection is welding, such centrifuge bowl is more steadily in performance and working time.

We take a 200gpm HDD mud system to Australia for Drill 2012 exhibition, Drill 2012 is organized by Australian Drilling Industry Association (ADIA) for drilling machines including drilling rig, mud pump, drilling tools, mud recycling system, etc.

This 200gpmHDD mud system also can be used for water well drilling, 150~600meters, the required treating capacity is 150~200gallons per minute.

Since you may do not want to pay more money to recycle the water well drilling mud, it is different with oilfield drilling mud which is consist of expensive mud material, you only want to recycle it and to meet environment protection regulation, GN 200gpm mud system will be your best choice for low cost and high performance-cost-ratio.

Submersible slurry pump can be used for drilling application, mainly to pump the slurry from the mud pit to shale shaker, second to pump the mud to decanter centrifuge( there is another type screw pump to feed for centrifuge, but submersible slurry pump can save place in the tank for compact footprint).

Especially for small drilling applications, such as HDD, they are not closed loop mud tank system, their drilling mud flow to a mud pit first, then use a submersible slurry pump to pump it to the mud system for cleaning.
