The client is local drilling client for HDD project. The client is providing water well drilling contract to government companies, government oil drilling companies etc. Last year in Feb, 2015, the client bought two sets mud cleaning system. Each set mud system only with one mud recycling tank, mounting with one set shale shaker & one set mud cleaner.

Recently, the client is requiring one more compact mud system for water well drilling, 500gpm system with two tanks. One shaker tank is with shale shaker and mud cleaner, one mud mixing tank with agitators or centrifugal pumps.

Simple introduction of GN 500gpm mud system as below.

One shale shaker mud tank system including: one set shale shaker, one set mud cleaner, two sets centrifugal pumps. The shale shaker is GN patent 3 panel shale shaker, which have over 5 years jobsite experience. The shaker can work well in different hard conditions. The mud cleaner is GN 3 panel mud cleaner with GN compact design, down deck shaker and desilter cones. Another tank is mud mixing tank with mud agitators, mud guns and mud hopper for chemical mixing.

Except for this mud system, GN drilling waste management equipment is also very popular in the world.

Waste management centrifuge: GN decanter centrifuge is working after replacing USA brand centrifuges. The centrifuge can work for solids control, waste management, waste water treatment ect.  In solids control application, 2500rpm is generally used for mud weight cutting, and 1800rpm to 2000rpm is generally used for barite recovery.  In drilling waste management, 2500rpm to 3000rpm is generally used for removal the fine solids. In waste water treatment, higher speed centrifuge is required after chemical enhancement.

Vertical cuttings dryer is also called VG dryer, VG dryer can treat the drilling cuttings discharged from shale shaker, the OOC after VG dryer can reduce to about 3% to 5%, and the dry solids can be collected by cuttings skips and transport by trucks to a cuttings center for final treatment.
